Differentiated Materials Target End-Use Component Production

The Xtreme 8K is the next step in the Additive Manufacturing 2.0 revolution, bringing proprietary, top-down DLP technology to production scale. Unprecedented speeds, power density, and materials properties make the 3D printer a high-powered manufacturing system that can produce a variety of parts without traditional tooling. The production capacity of each Xtreme 8K allows customers to manufacture thousands of large parts, like cushions, or over 5 million small parts, like earbuds, per year in custom geometries not possible with traditionally manufactured goods. 

And to get customers to production, we’ve tailored a resin portfolio for the Xtreme 8K with differentiated photopolymers that serve the material requirements of end-use products. Targeting some of the best property sets available, these premium materials are available on the Xtreme 8K, the largest DLP build volume on the market. We target materials that make parts less dense without a strength drop-off; thus, they are best partnered with optimization for de-densification to add value through lightweighting. 

Stress-Strain curve evaluations traditionally factor out the design to evaluate how a material will perform. However, in the world of additive manufacturing, 3D architectures change the game. Designers can now look at materials in a more toughness-per-density way to optimize the strength-to-weight ratio (proportional to performance-to-cost ratio) of their component. 

Our technical support team consists of synthetic organic chemists, materials engineers, mechanical engineers, and applications engineers who aim to help manufacturers evaluate, design, or optimize applications for production in Xtreme 8K work cells. Whereas lowerpart density in traditional manufacturing means a material can handle less stress, our customer service team uses design and simulation expertise, including topology optimization and parametric modeling, to sustain target stress values while dramatically reducing weight and thereby materials usage and cost. 

Read on for an overview of the industry-leading materials available on the Xtreme 8K:

Tough, Rigid Plastics

Henkel LOCTITE® IND 147

Have an application that requires a unique geometry with service temperatures over 120° C? LOCTITE IND147 has the highest heat deflection temperature (HDT 291° C at 0.455MPa) in the industry. It’s the Xtreme 8K go-to material for aerospace, industrial tooling, and molding applications due to its outstanding temperature resistance and high dimensional stability.

Evonik INFINAM® ST6100L

With a high dimensional stability and temperature resistance, Evonik INFINAM ST6100L is an excellent choice that allows designs to be optimized with lightweighting to less material to reduce cost per part. With a leading Tensile Stress at Break (89 MPa), it’s a great choice for industrial fixtures, tooling, and molding applications. 

Henkel LOCTITE® 3843

For semi-flexible, engineered end-use parts that don’t have as high of a heat requirement, the Xtreme 8K works with LOCTITE 3843 for its high IZOD Impact Strength with high elongation at break. This high strength and strain combination is well suited for housings and enclosures.

Henkel LOCTITE®  IND 405

LOCTITE IND 405 is the choice for tough, durable goods like consumer products due to its toughness, impact resistance and elongation at break of more than 100%​. This higher strain tolerance to bend, bows, and provide more flexibility is ideal for end-use applications like bike helmets or other sporting equipment.

Elastomers and Foams

DuraChain™ Elastic ToughRubber™ 90 

With the highest tear strength on the market, ETR 90 is the ideal choice to 3D print rubber components that are flexible and tough. It’s elastomeric in its entire thermal range (between -62°C and 86°C) with Shore A 90. Due to its high-strength combined with high elongation resistance with high dimensional stability, ETR 90 is best suited for flexible, end-use parts and tough, elastic components, even those operating at extreme service temperatures. 

DuraChain™ Elastic ToughRubber™ 70

For applications with demanding elongation, ETR 70 is the Xtreme 8K’s rubber of choice due to its high elongation resistance with high toughness​. Highly-elastic with a 400% elongation, it’s best suited for flexible, end-use parts like gaskets or tough, elastic components that operate in a range of temperatures like housings with vibrational damping. 

DuraChain™ Soft ToughRubber™ 

Tougher than other 3D printed options on the market below 40 Shore A hardness, STR is the Xtreme 8K rubber of choice for soft, flexible, functional parts with a silicone-like feel with toughness and strain tolerance. Its softness combined with high elongation resistance and high printing resolution make it ideal for end-use parts like earbuds or wearable devices. 

DuraChain™ FreeFoam™

A new family of photopolymer resins containing a heat-activated foaming agent, after printing FreeFoam parts are expanded during foaming in an oven, creating a closed-cell foam with tight dimensional accuracy. Producing parts in lattice structures instead of solid foam blocks allows foam manufacturers to dramatically reduce the amount of material used and waste generated while producing foam with less waste.
