¿Por qué utilizar gases industriales en la Fa-bricación aditiva?

Independientementedel procedimiento [Fu-sión selectiva por láser(SLM, por sus siglas eninglés) o haz de elec-trones (EBM, por sus si-glas en inglés),deposición de materiaen forma de polvo o hilo

(DMD, Direct Metal Deposition)], la fabricaciónaditiva o impresión 3D permite diseñar nuevaspiezas con formas geométricas complejas o connuevas funcionalidades mediante la adición decapas sucesivas de materiales.

Aunque solo representan una pequeña parte dela estructura de costes de las piezas metálicas,los gases son, sin embargo, indispensables parael funcionamiento de las máquinas, y, en conse-cuencia, requieren que se garantice la continui-dad del suministro.

El principal gas empleado para la fabricación depiezas metálicas es el argón pero, según los ma-teriales, también pueden utilizarse el nitrógeno oel helio.Naturalmente, estos gases deben utilizarse encondiciones de seguridad controladas (por ejem-plo: riesgo de anoxia).

Air Liquide suministra con fiabilidad nitrógeno(N2), argón (Ar) y helio (He), que intervienen entoda la cadena de valor:• La fabricación del polvo, el reciclaje y el alma-cenamiento: inertización, plasma,• La construcción de piezas: inertización la cá-mara de construcción, lecho de polvo, proyec-ción...• El postratamiento: tratamientos térmicos, lim-pieza con CO2Los gases industriales evitan cualquier deforma-ción o combustión de la pieza durante su impre-sión a alta temperatura.

SELECTIVE LASER SINTERING (SLS)

Selective laser sintering (SLS) is a rapid prototy-ping process that uses a CO2 laser to first heat apolyamide-based powder on a preheated benchand then builds it up in layers into a solid body.The material is only melted until the particles par-tially combine. As a result, the surface can bemore porous than in SLA and Polyjet processes.Thanks to innovative mirror technology, evencomplex geometries with undercuts can be pro-duced in the SLS process. conventional produc-tion processes are quickly reaching their limitshere. The basic material polyamide is providedboth raw and as a composite material with glassand carbon fibre components. You can also useour individual aftertreatment options

SELECTIVE LASER MELTING (SLM)

Selective laser melting (SLM), selective laser-melting) is only suitable for the production of 3Dproducts made of metals. The basic material isavailable in powder form and is built up additively(= in layers).In difference to the SLS process, the powder ma-


terial is not sintered, but melted by the energy ofthe YAC laser in a chamber filled with protectivegas.

With this process, almost all complex and func-tional prototypes can be produced in record time.The result is characterized by high stability andtemperature resistance. Suitable materials for theSLM process are aluminum, stainless steel andtool steel. Please also inquire about our individualaftertreatment options.

STEREOLITHOGRAPHY (SLA)

In stereolithography (SLA), the printing object isplaced on a platform wetted with polymer resin ina liquid bath. A UV laser hardens the processingpoints layer by layer by lowering the mould to

form an high-resolution 3D object with fine struc-tures and smooth surfaces. This rapid prototypingprocess is ideal for the fast and cost-effective pro-duction of design and functional models. The pro-ducts can be used in a wide range of applicationsin marketing and product validation. Within thescope of our vacuum casting process we use theSLA process for the fast and safe production ofthe master model. You can also use our indivi-dual aftertreatment optionsPOLYJET / MULTIJET

The Polyjet process is very similar to the classicinkjet printer, and can be described here as a 3Dprinter in particular. Multiple print heads with finenozzles spray an acrylic resin-based photopoly-mer onto a platform and harden the processingpoints with downstream UV lamps.

Multijet technology is based on the same princi-ple and its hybrid process allows simultaneousprocessing of different materials.Thus, different degrees of hardness from elasticto hard can be realized.

Both technologies are ideally suited for functio-nal and complex geometries with high demandson levels of detail and surface quality.

MIM-Master Neo (Next Generation MIM)

The MIM-Master Neo continuous walking beamsintering furnace and the corresponding opera-tion procedure for the new furnace represent thenewest development for continuous furnaces forthe production of metal injection molding ferrousand non-ferrous products. The MIM-Master Neofurnaces are the next generation of continuousfurnaces for the production of MIM components.

The MIM-Master Neo is built based on our well-established state of the art technology which en-ables a coupling of continuous residual debindingand sintering processes, the MIM-Master series.

The new design scrupulously combines the low-vibration ultra-smooth charge tray movement onthe MIM-Master walking beam with an increasedproduction capacity, which is more than 120%greater than the last generation MIM-Master. Fur-thermore, this is achieved with a smaller furnacefootprint, thereby reducing the gas & energyconsumption by about 40% and the investmentcosts by approx. 35%, relative to the last gene-ration design, taking an example of a MIM-Mas-ter 10XL.

Additional advantages of MIM-Master Neo are its

availability with the new and improved 3rd gene-ration Continuous Catalytic Debinding unit. A newmulti-level integrated temperature control (CQI-9TUS/SAT compatible) is supplied as a standard.In addition, recent developments such as thetwo-stage torch ensure that gases that leave thefurnace are odorless and environment friendly.

Novel complimentary modules could, moreover,be coupled with the MIM-Master Neo: e.g. theICS Iso-Cool System. This ensures controlledcooling rates of up to 180 K/min uniformlythrough all product layers, or the Hydrogen Ge-nerator (HG), for H2 generation inside the equip-ment with no additional tank and H2-pipingrequired from the customer side.

For the production of CIM products our productrange now also includes an innovative “Next Ge-neration” continuous debinding and sintering fur-nace for CIM.

Surface treatment - an essential step in addi-tive manufacturing operations

In recent years printing methods, printers and thematerials for additive manufacturing have under-gone a rapid development.

Today 3D printing is no longer just a method forprototyping but has firmly established itself as atechnology for volume production.


However, components made by additive manu-facturing require extensive post processing, achallenge that is frequently underestimated andnot taken seriously.

Already during the design phase for a new pro-duct AM users must take into account and re-solve issues regarding suitable, cost-efficientpost processing including surface refinement.This ensures that the expected work piece cha-racteristics can be achieved. Today the post pro-cessing of 3D printed components is still donewith costly and highly erratic manual operations,which make a cost-effective, industrial productionpractically impossible. The right know-how andsuitable equipment are key factors for an econo-mically viable and successful use of additive ma-nufacturing

State-of-the-art post processing of 3D printedcomponents offers many benefits:

Increased productivity due to shorter proces-sing times

Higher cost-efficiency due to automated postprocessing operations

Improved component performance due to animproved surface finish

Creation of new business opportunities due tolower costs per piece

New fields of application due to improved com-ponent performance

Faster implementation of the 3D printing tech-nology thanks to cost savings during the post pro-cessing phase

Powder particlesize for every re-quest

The BLUE POWERa t o m i s a t i o nplants have beenparticularly des-igned for the flexi-ble and economicproduction ofsmall-scale metal

powder batches. Traditional large-scale produc-tion plants cannot provide this economic advan-tage. Frequently changing alloys in productionrequire high cleaning efforts to avoid cross conta-mination. Particularly in R&D or precious metalpowder applications small amounts of variouskinds of powder are frequently required, oftenalso new types of alloy powder not available onthe market. Especially fast developing applica-tions like SLM and MIM require more and morespecialised metal powder.

High quality metal powders

Our atomisers produce spherical, flowable metalpowders with mean particle sizes between ~1and 200 µm for e.g. additive manufacturing, sol-dering or foam sintering processes, as well asMIM and other powder metallurgy procedures. Toobtain specific metal powder characteristics, the


AU machines work with different easy-to-changenozzle systems: free fall and close coupled ato-misation nozzles. Flow optimisation in the spraychamber ensures an increased powder quality(avoidance of satellites).

Tantalum and Niobiumcontaining powders for AM

While 3D printing enlarges the scope of manu-facturing possibilities, the intrinsic properties ofmaterials applied can limit the range of accessi-ble applications. In this context Ta and Nb as wellas new Ta and Nb-based alloy powders canserve special fields of application.

Due to their unique properties such as high mel-ting points, high corrosion resistance, excellentchemical resistance as well as high thermal andelectrical conductivity Ta/Nb or alloys containing

those elements are suitable for a wide range ofhigh-tech applications e.g. chemical processing,superconductors, energy, or high temperatureenvironments. Moreover, additively manufactu-red Ta/Nb containing alloys are a promising al-ternative for optimization of mechanical andbiological performance parameters in medical im-plants.

Multinary alloy compositions or high-entropy al-loys containing Ta/Nb are thereby especially ofinterest to design completely new intrinsic mate-rial properties that can provide superior solutionsin challenging applications especially when com-bined with the freedom to build complex struc-tures in AM processes.

Customized Materials for customized parts

3D printing allows for the creation of customerspecific parts. This aspect is especially crucial forapplications such as e.g. medical implants as thebody structure of each patient is unique. Toachieve optimized healing adjusted implants areof utmost importance.

Besides the ability to create customized partseven down to batch-size one production custo-mized material composition can allow the des-igner of parts to take unique requirements intoaccount.

We develop and produce alloys containing Ta/Nbin customer specific composition allowing ourcustomers to design a material that is perfectlyadjusted to the specific needs of their customersand the respective applications.

target of producing green hydrogen at USD1.5 per kilo* by 2025, to outcompete fossil al-ternatives.

Cost reductions through scale-up of productionto multi-GW scale, growing the organization toadd capacities and capabilities, and investing intechnology for the near- and long-term are cru-cial components in ensuring that Nel continues tobe the global leader in the hydrogen industry.

"Green renewable hydrogen is set to outcompetefossil alternatives, and Nel is placed in the centreof this transition. We’re today launching our targetwhich should enable our customers in certainmarkets to produce green renewable hydrogenfrom a large-scale Nel facility at 1.5 USD/kg fromlow cost renewable power, already within 2025.Achieving this would allow green hydrogen tostart to reach fossil parity, representing one of themost significant achievement for zero-emissionsolutions and a carbon neutral planet,” says JonAndré Løkke, Chief Executive Officer of Nel.

Nel’s Capital Markets Day 2021 (CMD) outlinesthe strategy and ambitions towards 2025, ad-dressing the current hydrogen market of 70 mil-lion tons, which, by the Hydrogen Council, isexpected to grow by 8-times by 2050, largelybased on green hydrogen.

“The hydrogen market is already large, but withonly a fraction served by electrolysis, there aresignificant opportunities to turn the existing mar-ket green. In addition, we see a regulatory lands-lide across the globe, with the EU and the USpledging hundreds of billions of dollars into theirzero-emission programs where hydrogen servesa vital part as the energy carrier of choice. Thegrowth will not only come from industrial applica-

tions, but also from transforming the current die-sel-based heavy-duty transportation to run onzero-emission and cost-efficient green hydrogen.These developments require low-cost electroly-sis and ultra-fast fueling, both areas where Nel isthe global leader,” Løkke adds.

Taking electrolysis to GW-scale

Nel is expanding the electrolysis production to ac-commodate large-scale projects by constructinga fully automated manufacturing facility at He-røya, Norway. Test production of the first 500 MWproduction line will commence in the secondquarter of 2021 with start of commercial ramp-upin the third quarter 2021. Based on the securedfacility at Herøya, Nel today outlines the potentialto expand the production capacity at this facilitybeyond 2 GW annually.

“Herøya represents the first industrial-scale pro-duction of the most efficient electrolysers on themarket, at a game-changing low cost. The Nelteam is continuously working to drive down thecost of hydrogen, where scale-up is key, and willcontinue to assess the exact timing for the nextexpansion step. A 2 GW production capacity ofelectrolysers would represent a potential of four-to-five million tons of CO2 reductions for our cus-tomers, or ten percent of the annual CO2emissions in Norway,“ says Jon André Løkke,and continues:

“Nel uniquely covers both PEM and alkaline tech-nologies, each with their respective advantages,and we will continue give them our full supportand equal priority. The technology roadmap high-lights our priority on large-scale products, conti-nuous improvements, and lowest total cost ofownership for our customers. The hydrogen in-dustry will become increasingly competitive andNel therefore needs to continue to invest in orga-nization, technology, and equipment to remain inthe forefront of the industry.“

Price and ultra-fast fueling is key to outcom-pete diesel

Nel has delivered more than 110 hydrogen fue-ling stations (HRS), H2Stations™, in 13 differentcountries. The global HRS market is expected togrow by 30 percent annually towards 2030, with11,000 installed fueling stations, in addition to so-


lutions for fueling of private trailer parks, trains,ferries, etc.

“The only way to transform heavy-duty trans-portation is to beat diesel at the pump. In addi-tion to green hydrogen reaching fossil parity atproduction, we have to enable fast fueling of hy-drogen in a reliable and cost-efficient manner tobe able to beat fossil alternatives. Nel has atechnology roadmap enabling fueling in 10-15minutes of a heavy duty truck to achieve a rangeof 1,000 km, and we are in a good position tocontinue to lead the hydrogen fueling industry,“Jon André Løkke says.

Reiterates strong market outlook

Nel reiterates the confidence in the long-termpotential for the industry, supported by the“green recovery” outlined by various govern-mental initiatives. The company aims to capita-lize on the opportunities by leveraging on theposition as a technology front-runner, continuedhigh focus on safety, global presence, scalabi-lity, cost leadership, strong financing, and pre-ferred-partner status for industry participants.

“Large opportunities also represent major chal-lenges for Nel going forward, as maintaining aleadership position requires large investments,rapid expansion of the organization, and execu-tion of large-scale projects across the globe inan increasingly competitive environment. In2021 alone, we will add more than 100 new col-leagues, deploy over 25% of the capital raised in2020 in plant, equipment, and technology deve-lopment projects, and add more capacity as re-quired by the market. The Capital Markets Daywill unveil how Nel will address these chal-lenges, as an emission-free future depends ongreen hydrogen,“ Løkke concludes.

Efficient Product Design is Not an AlienConcept - 3 Reasons to 3D Print Prototypes

By Jordi Drieman, 3D application specialist,Mimaki

Developing a product or part can be a long pro-cess for even the most experienced or creativedesign team. Unless they can 3D print their pro-totypes.

In many cases, using 3D print technology can bea game changer when it comes to a morestreamlined, cost-efficient, and creative designprocess. Here is why…

1. Quality – The first reason to chose to 3Dprint a prototype is the quality compared to moretraditional methods of prototype production. Thecolours and textures achievable with 3D printing- especially with Mimaki’s 3DUJ-553 and 3DUJ-2207 systems, that have been designed for ac-curate reproduction of over 10 million colours -make the prototype virtually indistinguishablefrom the actual product the team foresees. Evenif the product has complex, interlocking parts, 3Dprinters can produce prototypes with numerous

pieces fully and correctly assembled, ready forapproval.

Being able to visualise a product design in sucha realistic and precise way, enables the designteam to clearly communicate their vision, spee-ding up more constructive feedback to quicklyprogress the design process.

2. Efficiency – Not only can the quality of a3D printed prototype speed up approvals of adesign concept, but often the speed of 3D prin-ting increases the efficiency of the design to pro-duction workflow too. In addition, once thefeedback on an initial concept has been received,design iterations can be made by simply adjus-ting the 3D file and therefore, implemented morequickly and cost-effectively. The time saved atthis stage not only enables a smoother, less chal-lenging route to product approvals, but couldeven enable a quicker go-to-market strategy –crucial for many brands needing to react to mar-ket demands as fast as possible.

3. Creativity – With time and cost restraintsat a minimum when 3D printing prototypes, des-igners can also enjoy more creative freedom.They can fully explore and experiment with diffe-rent concept ideas or create multiple versions ofone product prototype with even minor changesto the design. The freedom to visualise moreconcepts than resources would usually allowcould lead to a more innovative end product. Anexciting prospect for any brand!

How to avoid contamination during debinding

In the polymer degradation step, the evaporated bin-der can condense as a liquid or as a powder.

For this reason TAV VACUUM FURNACES designedand installed containers able to collect the degradationproducts of the debinding.The collection, located in specific storage systems, al-lowsaspecific removalof thestearateexcludingconta-mination of the thermal chamber and the samplesthemselves.

The ideal solution is to install a storage tank and a trapin series, all supported by an efficient cooling system.

The storage tank is used for the collection of stearatewhich condenses on the cold walls in the liquid phase.In case of excessive accumulation of post process bin-der in the tank, the tankcanbedisassembledandclea-ned.

The degradation products in solid form are insteadconcentrated in one special trap. The trap consists ofwater-cooled copper coils surrounded by metal straw.In addition, there are steel grids with gradually finermeshes from bottom to top able to filter the decompo-sed binder with increasing efficiency.

The cooling system of the furnace is equipped withan impeller present in the area below the system.Thecooling impellerhas thepurposeofsuckingair fromthe outside and transferring it to the furnace avoiding to

Cómoevitar lacontaminacióndu-rante la desaglomeraciónEn laetapadedegradacióndelpolímero,elaglutinanteevaporado se puede condensar como líquido o comopolvo.

Por este motivo TAV VACUUM HURNACES diseñó einstaló contenedores capaces de recoger los produc-tos de degradación del desaglomerado.La recogida, ubicada en sistemas de almacenamientoespecíficos, permite una extracción específica del es-tearato excluyendo la contaminación de la cámara tér-mica y las propias muestras.

La solución ideal es instalar un tanque de almacena-miento y una trampa en serie, todo ello respaldado porun sistema de refrigeración eficiente.

El tanque de almacenamiento se utiliza para la re-colección de estearato que se condensa en las pa-redes frías en la fase líquida. En caso de acumulaciónexcesiva de aglutinante posterior al proceso en eltanque, el tanque se puede desmontar y limpiar.

En cambio, los productos de degradación en forma

sólida se concentran en una trampa especial. Latrampa consta de bobinas de cobre refrigeradas poragua rodeadas de paja de metal.Además, hay rejillasde acero con mallas gradualmente más finas de abajohacia arriba capaces de filtrar el aglomerante descom-puesto con mayor eficiencia.

El sistema de enfriamiento del horno está equipadocon un impulsor presente en el área debajo del sis-tema.El impulsor de refrigeración tiene como finalidad aspi-rar aire del exterior y trasladarlo al horno evitando queentre en contacto con la cámara térmica.

La creciente omnipresencia de la fabricación aditivatanto a nivel tecnológico como comercial, ha llevado aTAV VACUUM HURNACES a afrontar y apoyar estatecnología con sistemas cada vez más específicos dedesaglomerado y sinterizado.

Binder-Jet 3DPrinting

Conventional sub-tractive metalwor-king processesgenerate a lot ofwasteandare time-consuming. Theseprocess routes arealso very restrictiveon product designfreedom. On the

other hand, Binder-Jet 3D printing process is a form ofthe additive manufacturing process that results in mini-mum OR no wastage and offers almost 360-degreefreedom on the design of the components.

Also called as Metal Jet 3D printing, the Binder-Jet 3D

printing process is an evolution of another decade +older AM process called Direct Metal Laser Sintering(DMLS). Binder-jet 3D printing enables the productionof proto-samples within days, involves no upfront too-ling costs. The process allows infinite design changesduringproductdevelopmentwithout timedelayhelpingthe design engineers to get to their optimum designquickly and at the lowest cost.
