RF-Plasma Spheroidization

In 2014, at the completion of a four year celebrity project in Platinum, research began for the development of Additive Manufacturing systems for Platinum Group Metal Powders and focus on Iridium.

When atomizing micron powders at higher melting temperatures, the ceramic materials used in the melting crucible and nozzle can potentially break down and become inclusions in the metal supply.

Tekna Plasma Systems, which specializes in inductive plasma, developed a Spheroidization process used for Refractory Group Metals which showed a potential for purity in our application 

A collaboration with A3DM for research configuring a small laboratory size reactor system suitable for Platinum Group Metal experiments  in 2015.

For potential PGM catalysis applications, purity of our feeding stock was to be a high priority which ruled out most of these traditional technologies in use

In June of 2015, A3DM and Tekna Plasma Systems entered into an exclusive agency agreement to facilitate the sales of the Tek15 plasma systems for precious metal applications.

A3DM provides plasma research campaigns for US government laboratories and industrial clients interested in process development and equipment purchases

Plasma research campaigns have been considered for Bulk Metallic Glass Alloys, Rare Earth Elements, and Carbide, Oxide, and Nitride materials  ( Boron,Tungsten, Silicon, etc )

Precious Metal DMLS

PRESS RELEASE 

Birmingham, England –March 1, 2014 –Cooksongold, worldwide supplier for precious metals in the jewelry and watch industries has announced a strategic alliance with A3DM Technologies, a consultancy firm with deep roots in 3D printing technologies.

 

In partnership with EOS, the worldwide market leader in Additive Manufacturing equipment for powdered metals, A3DM and Cooksongold are launching the new M 080 DMLS machine and its associated precious metal powders.

 

Says Adler, “ The Cooksongold – EOS development of a turn-key solution for direct printing of precious metals will enable designers to produce unique luxury products unconstrained by conventional production techniques”.

A3DM collaborative work with EOS and Cooksongold focused on the development of DfAM principles for luxury products in Gold and Silver alloys.

 

A3DM also organized an international design competition with the support of Gemvision, the premier CAD software for jewelry design

 

Entry cost and productivity concerns in the luxury sector would however limit implementation in North America       

DfAM opportunities in the industrial and technology sectors have been developed

 

The nobility of precious metals and thermal characteristics have opened opportunities in applications for aerospace and nuclear R&D 

Light weight precious metal hollowware has shown some success in DMLS as well design methods that provide labor savings in articulating designs used in fine jewelry 

Silver and Gold parameter development has continued simultaneously on additional LPBF platforms for a variety of luxury alloys  

This project celebrates our work for the contemporary artist Jeff Koons and his iconic sculpture "Rabbit" c 1986.

 

In May of 2019, "Rabbit" was sold at auction for a record breaking $91.1M, currently the highest price ever paid for a work by a living artist 

 

A3DM digitally engineered and produced an edition series of platinum "Rabbit" sculptures in collaboration with Jeff Koons and LVMH designer Stella McCartney    

DfAM Expertise

Design for Additive Manufacturing ( DfAM ) as an engineering concept was driven by the 3D photo-polymerization process and practices of support generation. For any single material AM process this would become the critical guide in product engineering   

As an early Bureau Service ,A3DM was plagued by the repair and pre-processing of Stereolithography files ... many from CAD engineers with little experience in Additive Manufacturing .

Over 20 years of expertise and training MagicsRP....  

The transition of optical connectivity for telecommunication technologies typically requires significant investments in hard tooling.

DLP

Digital Light Processing

In 2003 A3DM was the first Envisiontec Perfactory development site placed in North America.

 The Texas Instruments DLP process was differentiated from the legacy laser based systems by potential increases productivity with a significant reduction in cost  

3D Voxel Printing

The DLP layer mask process adapted for photo-polymerization required significant ongoing research in collaboration with Materialise and Envisiontec in both processes and material science 

Unlike 3D Systems process systems, patterns inverted are pulled from a shallow vat requiring new support strategies to overcome stresses in peeling each layer from a surface. 

With increased adaptation by the jewelry industry, methods of gating for investment casting were incorporated as part of the DfAM criteria 

For more than a decade, A3DM has provided direct OEM support for the development of new Envisiontec photopolymer resins and process parameters for the investment casting process.

As an early adopter and contributor to the Wohlers Report, Steven is published and has been a speaker at numerous events on Additive Manufacturing for precious metals

The RapidToolmaker

Founded in 1996, A3DM pioneered design of "Rapid Prototyping" systems and processes for precision applications. Our mission statement to focus on the development of advanced piezo-electric multi-material additive process for investment casting patterns

Platinum / Ruthenium Casting 

Funded by a NASA research grant and founder of Sanders Associates, the RapidToolmaker launched A3DM as one of the first Bureau Services for precision casting patterns by "Rapid Prototyping" 

The unique precision capabilities of the A3DM "RapidToolmakers were supported by our development of proprietary thermal materials. A3DM patterns could be dissolved or pyrolyzed cleanly, mitigating challenges in the investment casting of other Rapid Prototyping materials .

Stereo-Lithography 

The Bleeding Edge of Technology

Computer Aided Design ( CAD ) provided SAENT product development with a precise surface area forecast of a design from which we could tailor precious metal content to meet client cost requirements

Digital design also provided a mirroring capability to create identical left and right earrings at a significantly reduced cost over "by hand" sculptors

Stereolithography ( SLA ) patterns for our geometries were well suitable as masters for wax injection molds. The waxes were then used as sacrificial mandrels in the karat gold electro-forming or metal investment casting processes

The Early Additive Years 

SAENT  E-FORMING  

A serial entrepreneur from an early age, Steven began a career path in additive manufacturing by ionic deposition of precious metals. Having made prior investments in the development of electrolytic processes for precious metal refining, applications for karat gold electro-forming was an opportunity to be explored  

SAENT research in digitally pulsed electrolytic processing at specific current densities was used to target individual elemental deposition on the surface of a sacrificial mandrel. Algorithms were established in order maintain consistent legal alloy content for gold on assay  

The thickness of deposits is sufficient to establish a self supporting hollow structure after dissolution of the sacrificial mandrel. Resulting karat gold electro-forms were found to be significantly harder than die-struck products and retain a shape memory.       

The World Gold Council supported development and promotion of our work at SAENT in North America in collaboration with Oxy Metal Industries in Geneva and Degussa Galvanotechnik GmbH in Germany. 

SAENT E-Forming developed products for several renowned jewelry brands including Charles Garnier, Harry Winston, and Tiffany & Co in the launch of a new technology and category of manufacture for fine jewelry

From a design perspective, the karat gold electro-forming process allowed young designers to create bold asymmetrical hollowware earrings that were lightweight and thus comfortable to wear.
