SLA (VIPER) The new generation of SLA equipment, offers the combination of either standard (0.127mm),or high-resolution (0.05mm) part building on the same system. The platform size of the VIPER is 250mm x250mm x 250mm, and offers both 'ABS' and 'PP' type material.

RIM (REACTIVE INJECTION MOULDING) A two part polyeurethene resin is injected under low pressureinto either a RESIN, SILICONE or ALUMINIUM tool, giving accurate, fast components of low to mediumquantities. This method produces runs of 50 to 1000 units per annum, which are achievable quickly and arecost effectively compared to metal injection mould tooling.

SLA parts are ideal for; presentation models, tooling masters, foundry / sacrificial patterns for standard

investment casting, and to test fit/form/function.

CAD (COMPUTER AIDED DESIGN) Experienced detailing/analysis CAD operators are able to withcustomers CAD files, or produce CAD data to their customers needs. The preferred file format for RapidPrototyping is an STL.

RESINS FOR SLA PARTS AME use 2 different types of resins in our machines:

- FLEXIBLE: PP like, and is ideal for flexible parts such as clip features etc- WATERCLEAR / WATERSHED: ABS like, clear and waterproof. Ideal for bottles, lenses etc.

SLA (3500) The larger SLA facility allows larger components to be produced in a single piece, quickly andcost effectively. The material available has 'ABS' properties.

VACUUM CASTING Usually cast from a silicone tool, a 2 part polyeurethene resin is applied under vacuuminto the cavity. This method usually produces 20 - 25 units, depending on material. This makes vacuumcasting ideal for low volume production runs or 'first of' production quality samples.

SILICONE RUBBER TOOLING Liquid silicone rubber is poured over a master pattern (usually SLA) andallowed to cure under vacuum.

SLS (SELECTIVE LASER SINTERING) Allows flexible components to be produced in either Duraform(nylon), GF nylon (30% Glass filled nylon) for functional prototype models.

THERMOJET A 3 dimensional wax printer which produces fast, accurate modelling for concept validation,patterns for tooling or lost wax investment casting patterns.

DATA SHEET: frequently asked questionsHOW DOES RAPID PROTOTYPING WORK? Rapid Prototyping is neatly described in simple terms as3D Printing. The increasing pace of innovation now gives the designer massive opportunity to reduce risks,costs and time scales in their projects by efficient use of RP technology. Rapid prototyping quickly delivers prototypes that are constructed in an additive, layer-by-layer process that isdriven by 3D CAD data. Rapid Prototyping delivers physical representations of your complex designs in aslittle as one day.

It is important to note that rapid prototyping has become a very loosely used term to define any process thatreduces the time to receive a prototype. Machining, casting and molding techniques have all been looselygrouped under the rapid prototyping umbrella.But, the true definition of rapid prototyping is those technologies that additively "grow" a design.Stereolithography and selective laser sintering are two of the leading technologies.

WHAT IS RAPID PROTOTYPING? Although individual rapid prototyping technologies vary substantially,there are common elements within each process.

- Generate an STL file from 3D CAD data.- Starting with the bottom most layer, begin to solidify the part.- A laser or ink-jet head solidifies the first cross-section of geometry.- The solidification process is repeated for subsequent layers.- Upon build completion, the prototype is postprocessed (benched).- Remove unwanted, residual material.- Sand, grind and polish the part to desired surface finish.

Since the laser has complete access to all geometry on any single layer, extremely complex parts can be builtin rapid prototyping without impact on construction time.

HOW LONG DOES IT TAKE? Although there are no typical parts, AME has found that the process has

typical time spans of:

- File preparation: 0.5 to 2.0 hours- Build time: 0.5 to 15 hours- Postprocessing time: 0.25 hours to 6 hours

AME's average delivery is just two to four days. For some projects, the delivery can be as fast as just a singleday.

HOW MUCH DOES IT COST? For a prototype that is moderate in size and highly complex, rapid

prototyping can be less expensive than traditional prototyping methods. A bureau provider will typically beable to provide quotations in minutes of receiving a copy of the STL file. Using the example of the ubiquitousmobile phone the casings for that product would typically cost less than 750.

WHY USE RAPID PROTOTYPING? The "real", physical prototype quickly and clearly communicates allaspects of a design. Eliminating ambiguity, rapid prototyping facilitates the early detection and correction of design flaws.Rapid prototyping has proven beneficial in numerous ways. Some of the more common applications include: - Form, function & fit evaluation- Ergonomic studies- CAD database verification- Customer samples- Pattern development for metal castings or tooling- Trade show samples- Product photography

BENEFITS OF RAPID PROTOTYPING? On a corporate level, the benefit of rapid prototyping is that it isinstrumental in slashing time-to-market while protecting product quality. The bottom line is increased marketshare and revenue.

HOW CAN I GET A QUOTE? The best way to get a quote is to supply 3D CAD data via email [email protected] with all of your requirements such as materials,quantities and colours.. We will advise the best route for your project and often will give more than one option.In the majority of cases, quotations can be supplied by return email within 4 hours from one of our BusinessDevelopment Team. If CAD is unavailable, faxed drawings to 01909 550888 can be used to give anindication of costs which can be confirmed on receipt of 3D CAD data.

WHAT FILE TYPES ARE ACCEPTABLE? Many 3D file types are available. The most suitable file typefor Rapid Prototyping are STL, although we can taken many types. Native Pro Engineer and Solidworks files,

along with STEP, IGES, SAT and 3D DXF are also ideal file transfers. We can advise on the best file transfer type for your individual 3D CAD packages.
