Best Practices: Cleaning the Machine

A Clean Machine is a Happy Machine! Dedicate at least one hour a week to clean the machine and

surrounding area Cleaning the service station Cleaning the spreader roller Cleaning and lubrication Cleaning the sensor window When changing print heads clean the electrical contacts Cleaning the Debris Separator Emptying the Solid Waste

Presenter

Presentation Notes

”A clean machine is a happy machine!”. This is the single most important rule to follow. A clean machine is reliable, and it will produce the best quality parts. It will be easier to maintain and require fewer service visits from your servicing dealer. And if any problems do arise from either machine function or output quality, it will be much easier and quicker to troubleshoot if the machine is maintained in a clean state. We are all very busy and it can be a challenge sometimes to keep the machine and the surrounding area clean, but you should try to find at last 1 hour each week to clean the machine and the surrounding area. Many of these practices can be incorporated into the daily preparation of the machine for each job. Some operations are monitored by the 3DPrint software of which the operator is reminded of as needed. [Read some bullets from the slide…]

Best Practices: Clean the Service Station

Remove debris from the Service Station

Push down the lever to expose the rubber flaps and wash with distilled water

Presenter

Presentation Notes

After each build, the service station should be cleaned of any debris that may collect in the service station during the build. Use a small brush or a ‘pick’ to loosen and break up any material that may have clumped up in the service station. Rinse the debris down the drain hole with distilled water and the squeeze bottle supplied with the 3D Printer Use the same bottle to wash any debris from the rubber flaps. You can expose these flaps by pressing down on the small lever on the left side of the service station.

Best Practices: Clean the Parking Caps

Wash the pads with distilled water

Older ZPrinter 450 and 250 models only

Dry with clean paper towels

Presenter

Presentation Notes

The parking caps for the ZPrinter of older 450 and 250 models are located to the left and rear of the build chamber at the “parked” position of the print head carriage. These pads should be cleaned following each build by placing a folded paper towel under the caps and rinsing with distilled water from the squeeze bottle before drying the caps with a clean paper towel.

Best Practices: Cleaning the Squirt Holes & Spittoon

For Projet 660 & 860 models For ZPrinter 650 and 850 models

Clean the print head squeegee with distilled water making sure it is free of debris

Use the cleaning tool to clean the squirt holes on the before every print job

Cleaning the spittoon regularly will also help ensure that the print heads are kept clean when the machine is idle

Presenter

Presentation Notes

The service station for the ZPrinter 650 and 850 and ProJet 660 and 860 squirts the cleaning solution on the print heads and is squeegeed off. The cleaning tool supplied with the printer should be used to keep the squirt holes clean and free from any clogging. Rinse the squeegee with distilled water and wipe clean with a paper towel. Clean the spittoon regularly by lifting it from the housing; being careful not to spill any residual solution from the tray. Have a paper towel handy. Rinse the tray using distilled water then clean and dry with paper towels.

Best Practices: Part Orientation

Part orientation in the build chamber is critical to producing consistently great parts

Proper orientation will improve: Print Speed Part Green Strength Squash Reduction Accuracy (ex: for Mating Parts) Surface Finish Depowdering / Part Removal

Presenter

Presentation Notes

Part orientation in the build chamber is critical to producing consistently great parts. Part orientation can… Reduce the time it takes to print your part Increase the green strength of printed parts Reduce the “squash” effect on hollow, cylindrical parts and parts with overhangs Improve part accuracy Improve the surface finish Improve the ease of depowdering and removing parts from the build chamber

Best Practices: Part Orientation for Speed

Minimize the layers for shorter print times

3 hours, 37 minutes 8 hours

Presenter

Presentation Notes

The ZPrint Software automatically positions parts in the Build Chamber for maximum build speed by placing parts with the smallest dimension in the Z-Axis. By minimizing the number of layers in the Z-axis overall print time will decrease. The default justified position of a single part in the build chamber is to the right, to the back, and to the bottom. This default position is the best position for print speed.

Best Practices: Part Orientation for Strength

X-Axis / “Fast” Axis Strongest

Y-Axis / “Slow” Axis Strong

Z-Axis Less Strong

Presenter

Presentation Notes

The strength of an uninfiltrated part, otherwise known as the green strength, will be affected by its orientation within the Build Chamber. Parts that lie in the X-Y plane will be stronger than those aligned on the Z-Axis. If a part has a particularly delicate feature, such as a thin rod, align that feature in the X-Y plane for the greatest green strength. Once a part is infiltrated, it uniformly takes on the strength characteristics of the infiltrating product.

Best Practices: Part Orientation for Squash Effect

Size of the bead of powder in front of the roller decreases

Overflow side of build

chamber

Feeder side of build

chamber

Presenter

Presentation Notes

Squash effect results from an overhang being supported with only unprinted powder. For example, if a part is a hollow round cylinder, such as a scope, the weight of the powder above the cylinder will cause it to "squash” to something less than round, if there is no support underneath. When a new layer of powder is spread, powder closest to the feeder will be more compact than powder near the overflow side of the Build Chamber. The more compact un-printed powder will better support the weight of the powder above.

Best Practices: Part Orientation for Squash Effect

Presenter

Presentation Notes

To reduce squash, place cylindrical, hollow, and unsupported features, such as overhangs, towards the feeder side of the build chamber.

Orientation for Reducing Squash

Orientation of this part is incorrect • A bulky overhang has been placed high in the build chanmber

towards the front overflow (Powder is least dense here)

Overhang may sink into loose

powder

Orientation for Reducing Squash

Orientation of this part is correct • The part has been flipped so that the overhanging part in

now close to the bottom of the build chamber

Best Practices: Using Fixtures

Support over-hangs and cylinders Support complex and delicate parts

Support parts for transportation and display

Presenter

Presentation Notes

Using a fixture helps support delicate features for print removal and transportation and makes it possible to depowder areas where weaker geometry exists and infiltrate them locally to enhance strength and survivability. There are many situations where Fixtures are useful: Helping prevent "squash" effects for hollow cylindrical parts, or parts with overhangs Supporting delicate, thin parts and complex assemblies for easy removal from the printer and handling during post-processing Supporting parts during the automatic powder removal cycle. (Z450, Z650 and Z850 only) Increasing accuracy in the Z-Axis for parts with large overhangs Keeping multiple parts from bumping into each other, or into the Build Chamber walls during automatic powder removal. (Z450, Z650 and Z850 only) Fixtures can be post-processed to increase strength in order to use the fixture for transporting certain parts. They can even be colored and used to display the part it supported during the 3D printing.

Best Practices: Using Fixtures

Making a fixture Parts of a fixture

Presenter

Presentation Notes

When creating fixtures, we recommend starting with the default settings. After the fixture is created, use the Collision Detection feature in the View pull-down menu to ensure that the fixture in not colliding with the cradled part. Although, rare, if a collision is detected, minor changes to the settings will modify parts of the fixture to eliminate the collision.

Best Practices: Using a Witness Part

Make a witness part

No witness part

Witness part

Presenter

Presentation Notes

In most instances, the ZPrinter produces very even color. However, in cases where color consistency across a part is critical, the Make Witness Part command under the Edit menu can be a useful tool. The Witness Part is placed very close to, but not quite touching, the part and will pre-fire the Print Heads before they reach the model. This pre-firing of the print heads assures optimal jetting of the color binder through the print head jets, for optimal and more consistent color over the entire part.

Best Practices: Using Bleed Compensation

Enable Bleed Compensation to: Improve the overall

dimensional accuracy Improve the surface

alignment of mating and threaded parts

Presenter

Presentation Notes

Binder printed on powder will tend to overspray slightly, causing surfaces of a part to migrate outward. This is known as “bleed”. The Bleed Compensation check box can be found in the 3D Print Setup screen which can be opened from the File pull-down menu. Use Bleed Compensation when printing parts that need to be joined to ensure that the mating surfaces align properly or is a threaded component needs to be screwed into another part. Bleed Compensation should be enabled to achieve high accuracy. The bleed compensation values can be fine-tuned for your printer’s environment to achieve optimal accuracy by using the Bleed Compensation Gauge tool which can be found on the 3DS Central website. Use this tool to adjust the default bleed compensation values to dial in the highest achievable accuracy for your ZPrinter.

Best Practices: Depowdering

Gross depowdering

Fine depowdering

Brush / Lightly sand the

part to enhance color

Presenter

Presentation Notes

There are two types of depowdering: Gross Depowdering and Fine Depowdering Gross depowdering is the removal of the unprinted powder from the build chamber to extract the printed parts from the ZPrinter. This primarily involves use of the vacuum attachments. A long, soft bristled brush can be used as well to aid in the removal of the bulk of powder from the surface of the parts. the vacuum system will recover the unprinted powder and retrun it to the feeder to be used for the next print job. Fine Depowdering is the removal of residual powder from the surface of the printed model to prepare the part for infiltration. Compressed air from an air-wand, such as the wand in the Post-Processing Unit of the ZPrinter 350, 450, and 650, is very effective for removing residual powder from the surface of the parts that remains from gross depowdering. You can attach a small, flexible tube, such as a piece of surgical tubing, over the needle of the air-wand for fine depowdering of hard to reach areas. Always start with a low pressure air-flow to minimize the likelihood of damaging delicate geometries. Other tools such as a stiff, nylon brush or some 220 - 300 grit sandpaper are effective to improve the part's surface finish and color. Minor color variations on a part surface can be easily removed by brushing or sanding the affected area. Use compressed air to remove any of the brushed or sanded powder from the part, but do not blow any brushed or sanded powder into the powder recovery of the ZPrinter. Powder that has already been treated with binder has been chemically changed and should not be mixed with the unprinted powder in the feeder. To maintain optimum powder properties, be sure to occasionally add new powder into your recycled powder. It is recommended to keep the powder level in the feeder above 5”.

Best Practices: Depowdering

ProJet 160 / 260 / 360 ZPrinter 150 / 250 / 350

ProJet 460 / 660 / 860 ZPrinter 450 /650 / 850

Place the hollow side facing down Powder evacuates through the bottom Use fixtures with to protect delicate parts Fixture

Presenter

Presentation Notes

Part orientation should be considered for depowdering certain part geometries. For ZPrinters that are not equipped with the automatic gross depowdering system, such as the ZPrinter 151, 250 and 350; if the part is concave or has an opening or is hollow, place the hollow side facing up in the Build Chamber to allow for the removal of powder during the depowdering process. Uniformly remove the powder from the inside and outside of the part to prevent any damage to the part due to avalanching powder. If the part is delicate, create a Fixture to give it extra support and additional protection during powder removal. For ZPrinters that are equipped with the automatic gross depowdering system, such as the ZPrinter 450, 650 and 850; place the hollow side of a part facing down in the Build Chamber to allow powder to evacuate during powder removal. Build parts that are delicate with a Fixture, to give them extra support and additional protection during powder removal. Enable the Make Bumper option for added protection and for multiple parts in the chamber.

Best Practices: Drying the Part

Thoroughly dry the parts! ColorBond™ (formerly Z-Bond™) is

activated by moisture Removal of all moisture in the part

is crucial for great part-making: Deeper penetration of infiltrant Minimize off-gassing Eliminate bloom

Fixture with bumper

ZPrinter 650 Post-Processing Unit

Presenter

Presentation Notes

Moisture is used to bond each layer of binded powder to the previous layer by jetting binder onto successive layers of powder. Removing the moisture completely as a precursor to infiltration is crucial for several reasons: Deeper penetration of Z-Bond / Z-Max - Z-Bond is activated by moisture. If there is moisture present, the penetration of Z-Bond will be arrested resulting in a weaker part. Also, moisture from the part can contaminate the remaining Z-Bond in the dip tank or catch container. This will cause the Z-Bond to thicken; decreasing its performance for future infiltration applications. Minimize off-gassing - Moisture that is present in the core of thicker geometries can slow down and retard the curing process of Z-Bond. The evaporation of the moisture can cause off-gassing of the Z-Bond that can result in staining of surfaces that the parts and models are displayed on. Eliminate bloom - the phenomenon known as bloom is the outward expansion of the part geometry. Thoroughly drying the part will eliminate the likelyhood of bloom occuring. (An exaggerated example of bloom would be a dry sponge absorbing water.) Oven-drying ZPrinter parts, although not required, is preferred over air drying. An oven with heated horizontal airflow is recommended over an oven with radiant heat. Parts that are closer to the heating element can warp or discolor. Most parts can be thoroughly dried with an oven at 110° - 120° F in 2 – 3 hours; while air drying parts at room temperature requires a minimum of 24 hours. The ZPrinter® 650 is equipped with a heater in the Post Processing Unit (PPU) that will meet the needs of most users. If you do not have a Z650 model, or you are part of a high volume rapid-prototyping and model shop, you may benefit with a separate oven for drying multiple parts simultaneously. Commercial grade warm food holding cabinets are an excellent addition to the shop.

Best Practices: Infiltration

How far an infiltrate wicks into the part is based on its viscosity and gel time

Moisture reacts with infiltrants

2-7mm penetration is typical

Presenter

Presentation Notes

The deeper the infiltrant wicks into the part, the stronger the part How far an infiltrate wicks into the part is based on its viscosity and gel time Moisture reacts with our resins; for example Z-Bond is moisture activated, so the dryer the part, the deeper the infiltrant will penetrate into the part A 2- 7 mm penetration is typical; full penetration is possible if you have access to a vacuum chamber

Presentation Notes

Which infiltrant to use? For concept parts that do not require high strength or tooling; such as drilling, tapping or metal inserts, Z-Bond is the recommended infiltrant. It is a one-part resin with a 15 – 30 minute cure time that provides very good strength to ZPrinted parts. The preferred method of application is to dip the parts into the Z-Bond, or the drizzle method for delicate geometries. Epsom salt / water mixture is chemical free and can be applied with a light mist from a spray bottle or the dip method. Drying times vary with part geometry, and the part strength is low. Epsom salt / water may be preferred for classroom environments or for design reviews when higher strength is not necessary. A paraplast wax is available from 3D Systems for sealing parts and improving the surface finish. It can be used in combination with Z-Bond to give color parts a more vibrant look and a smoother surface, or as a stand-alone infiltrant that is stronger than the Epsom salt/water cure.

Best Practices – Infiltration: Prep

Before applying any infiltrant (ColorBond, StrengthMax, Wax, Water-cure) Read the product instructions carefully Wear gloves, safety glasses protective clothing during application. Always work in a well ventilated area Use sheets of teflon, freezer paper or wax paper to cover your work

area surface When working with ColorBond, have a good supply of paper towels

at hand for absorbing excess infiltrant

Presenter

Presentation Notes

Some preparative steps should be taken before applying Z-Bond™ to your parts Always read instructions carefully before using Z-Bond. There are instructions and MSDS available on ZCentral Wear gloves, safety glasses, and protective clothing during application. Always wear gloves We recommend using Rollpruf® 0716-513 gloves by MAPA® Adventech (fitted gloves which prevent sticking to resins). Always work in a well ventilated area – a fume hood is recommended Use sheets of teflon, freezer paper or wax paper to cover your work area surface and to rest your parts on for curing and for easy clean-up Have a good supply of paper towels at hand for absorbing excess Z-Bond

ColorBond Dip Pour ColorBond into plastic

container Gently dip your part for a few

seconds Drain excess liquid Promptly blot excess infiltrant

that has pooled on the part using paper towels

Lay your part on the glossy side of the protective sheet and allow to cure for ~15 minutes


Presenter

Presentation Notes

Pour enough ColorBond into a container, to completely submerge your part. Gently dip your part into the container with Z-Bond. Look for bubbles rising. If you don’t see any bubbles, let the part sit submerged for ~10 seconds, and then remove your part. If you see bubbles rising, wait until you no longer see bubbles, and then remove your part.�Once the part is removed, keep the part moving in your hands, while excess liquid drains back into the container. This will help prevent the part from sticking to your gloves. Note: Parts may become warm and may emit visible vapor. This is normal. Quickly and thoroughly wipe away any excess Z-Bond that may have pooled on the surface of the part using paper towels, and place your part on the protective, non-stick material. If you see liquid pool under your part after placing it on the non-stick material, move the part so it will not adhere to the surface.�Let your part cure and cool down before handling. Cure and cool time depends on your part’s geometry, but most parts are safe to handle within ~15 minutes.

After each use Using the funnel, return

any unused ColorBond back into the bottles

Store in a cool area, away from heat and moisture

Do not store ColorBond in refrigerator


Presenter

Presentation Notes

While the part cures, return any unused Z-Bond back into the bottles using the funnel, for future use. Be sure to cap the bottles tightly, and store them in a cool area, away from heat and moisture. Refrigeration of Z-Bond can lead to condensation in the container. Condensation will contaminate your Z-Bond.


Drizzle ColorBond Drizzle Z-Bond over part, moving part

around regularly until whole surface has been treated

Quickly wipe any excess Z-Bond off part with paper towels

Place part on a clean, non-stick surface and let cure and cool down before handling ~15 min.

While part cures, clean up any drips that have fallen into catch container using paper towels

Presenter

Presentation Notes

Although you will likely find that the Dipping method is the most preferred and efficient way to infiltrate your parts, the Drizzle method can be used for models with very delicate features; features which may be too thin to withstand the dipping process. In fact, often times, the drizzle method can be used in combination with the dipping method to produce great results. To use in combination with the dipping method, first drizzle delicate/fine part features with Z-Bond. After the delicate features have had a few minutes to strengthen, submerge the entire part in Z-Bond, following the instructions for the dipping method that we just reviewed. To use the Drizzle Method: Place a protective sheet, or preferably a catch container, on your working area. This will help contain any drips of Z-Bond. Use a 100g bottle of Z-Bond 101, or attach a spout to your 1-lb bottle of Z-Bond. Place your part inside your catch container and start drizzling Z-Bond over your part, moving your part around regularly until the whole surface has been treated. Quickly and thoroughly wipe off any excess Z-Bond off the part with paper towels as you go. When done, place your part on a clean, non-stick surface and let cure and cool down before handling. While the part cures, clean up any drips that may have fallen into your catch container using paper towels. Place infiltrated parts on protective, non-stick material (Teflon, freezer paper or wax paper). Let your part cure and cool down before handling. Cure and cool time depends on your part’s geometry, but most parts are safe to handle within ~15 minutes.


Epsom Salt Water cure Use spray bottle provided with kit Mix measure and mix water Epsom

salt until all crystals are dissolved Adjust spray to fine mist Spray a light coat of the salt water

over all sides of part Use fan, hair dryer or oven to dry

part faster

Presenter

Presentation Notes

The Epsom Salt Water cure method is preferred in some environments where part strength is not crucial or the environment is not conducive to using Z-Bond or Z-Max. Follow the instructions for mixing the Epsom salt with water being sure to dissolve all crystals. Use a fine mist to spray a light coat of water over the entire surface of the part – even the bottom For faster drying, use a blow-dryer, a fan, or an oven.


StrengthMax (formerly Z-Max 90) High strength two part epoxy Low viscosity for deep

infiltration: up to 10 mm Improved resistance to humidity

and water Excellent high-temperature

performance Create functional parts Clear appearance

Presenter

Presentation Notes

Z-Max is a high strength two part epoxy Z-Max has low viscosity for deep infiltration of parts up to 10 mm Improved resistance to humidity and water Excellent resistance to high temperatures: up to 200F Use Z-Max to create functional parts – infiltrated parts can be drilled, tapped and surface machined and attached to assemblies for testing Clear appearance for use with multiple color parts


Paraplast Wax Low cost infiltrate Low temperature melting point Easily achieve 100% infiltration Produces a smooth surface Enhances the appearance of color parts Use with ZW4 Waxer Can be used with parts infiltrated with

ColorBond

Presenter

Presentation Notes

If strength is not a key property, paraplast wax can be used as a low cost infiltrant The wax has a low temperature melting point; ~110° F When using wax, you can easily achieve 100% infiltration The wax produces a smooth surface and enhances the appearance of color parts Intended for use with ZW4 Waxer; but home-grown solutions are quite common and easy to produce Can be used in combination with parts infiltrated with Z-Bond to give parts a smooth finish and to enhance color.

Best Practices: Multi-part assemblies

To join multi-part assemblies, infiltrate each part normally

Sand the seams for test fit Drip ColorBond on mating

surfaces, hold together Apply CA accelerator for an

instant bond.

Presenter

Presentation Notes

If a particular part is too large for the build box, you can easily section the part into multiple pieces using Z-Edit Pro, print the individual pieces separately, and bond them together. Z-Edit Pro also allows you to add pins and holes so that the pieces join together correctly. Sand the seams and test fit until edges fit tightly together Drip Z-Bond on one mating surface and apply moisture to the other; I usually use a wet cotton swab. Hold the sections together; and apply CA accelerator to the seam for an instant bond. CA accelerator can be obtained in any hobby store. In-house we use BLAST 6000 from Cyberbond Use the same practices to join Z-Max infiltrated parts; sand the mating surfaces; apply Z-Bond to one surface and moisten the other; hold together and apply CA accelerator

Orient parts for maximum speed and strength

Keep depowdering in mind when setting up the build

Use fixtures, witness parts and bleed-comp when appropriate

Use the 3D view in the software to identify part placement and orientation in the build chamber

When gross depowdering use vacuum attachments to avoid damaging your part

Start with low air pressure when fine depowdering – gradually increase as needed

Oven dry parts prior to infiltration - or air dry

Mix recycled powder with fresh powder to maintain optimum powder properties

Share and benefit from user tips and tricks, posted regularly on the 3D Systems Message Board

Best Practices: Review

Presenter

Presentation Notes

Let’s review the best practices discussed today: You should always try to orient your parts for maximum speed by positioning your part to the RIGHT, BOTTOM - BACK. The shorter a build is in the Z-axis, the faster your print job will complete. 2) For gross depowdering leave room around your part to make removing it from the printer easier. 3) use fixtures for thin, delicate or overhanging features for successful part removal. Fixtures also help reduce squash. 4) When you are ready to depowder and remove your part from the printer, refer to the part location in the ZPrint software. 5) When gross depowdering, be sure to use your vacuum attachments to significantly reduce the chance of damaging your part. 6) You should always start with lower pressure when fine depowdering. Gradually increase the PSI as you go. 7) It is best to oven dry your parts before infiltration. Parts need to be dry for the best infiltration results. If you don’t have an oven, air-drying after depowdering will produce the same results, but will take longer. 8) To maintain optimum powder properties, be sure to occasionally add new powder into your recycled powder.
