Protolabs expands 3D printing options with hybrid PhotoSynthesis technology

Protolabs has expanded its 3D printing capabilities with the introduction of advanced PhotoSynthesis technology. Axtra3D Hybrid PhotoSynthesis (HPS) offers highly repeatable and finely detailed 3D printed parts at accelerated speeds. HPS uses both a precision laser and a digital light processing (DLP) system to simultaneously image the internal and external structures of the part – a dual 3D printing approach that overcomes traditional limitations.

HPS complements Protolabs’ existing range of carbon digital light synthesis (DLS) printers, which are used for projects with higher mechanical requirements. Both systems offer near-isotropic parts and smooth surfaces, but HPS is characterised by exceptionally high resolution compared to other 3D printing processes. This new technology allows Protolabs to address an even broader customer base and penetrate more production applications.

Typical applications for HPS include the manufacture of production-quality parts at high throughput rates, components with extremely accurate features for testing and validation, and cosmetic prototypes with crystal-clear surfaces.

“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 resin with high strength and good impact resistance, and ceramic-filled BASF 3280, which is often used for tools and moulds due to its high stiffness. These materials expand Protolabs’ existing photopolymer portfolio and offer customers even more flexibility in their choice of 3D printing applications.
