Protolabs Debuts Hybrid PhotoSynthesis Technology

Protolabs expanded its 3D printing capabilities by launching an advanced photopolymers technology. Axtra3D Hybrid PhotoSynthesis (HPS) offers repeatable and detailed 3D printed parts at higher speeds, the company reports. HPS uses a precision laser and digital light processing (DLP) system to image internal and external part structures—a dual 3D printing approach.

HPS complements Protolabs’ current Carbon digital light synthesis (DLS) printers for 3D printing projects that require stronger mechanical properties. Carbon DLS and HPS feature near-isotropic parts and smooth surface finishes, but HPS technology also offers high resolution when compared to other 3D printing processes, Protolabs reports.

Common HPS applications include production-grade parts with excellent throughput, parts requiring high-accuracy features for testing and validation, and cosmetic prototypes requiring glass-like surface finishes.

“We are committed to establishing additive manufacturing as a technology that can take companies from prototyping to production,” said Ryan Kees, Protolabs 3D printing global product director. “To help product developers, designers, and engineers do that, Hybrid PhotoSynthesis is another vital production option in our growing toolbox of 3D printing capabilities.”

Currently available HPS materials include Tough Black (Loctite Henkel 3843), an engineering-grade resin with high strength, impact resistance, and surface finish, and ceramic-filled (BASF 3280), a material often used for tooling and molding due to its high stiffness. Both materials expand Protolabs’ advanced photopolymer library, adding to the materials already offered for Carbon DLS.
