Programmable PhotoPolymerization P3™
Advantages of parts built with a Stratasys Origin One P3 Machine
Injection Molding Quality
Programmable PhotoPolymerization P3™ technology, an evolution of digital light processing (DLP) is ushering in a new era in 3D printing: the mass production of functional end-use parts.
P3 software precisely orchestrates light, temperature, pull forces and pneumatics to optimize prints for the best possible results.
With P3, injection molding part quality can be achieved, and a surface finish with incredible accuracy. P3 has a diverse and continuously growing range of high-performance materials.
End-use Part Production
P3 is a combination of several tightly controlled, programmable steps in the printing process. P3 extends DLP printing’s capabilities and supports the next generation of production applications made with photopolymers.
This powerful combination of production-grade technology and performance materials unlocks functional end-use applications in 3D printing with competitive throughput and part cost.
Strong Parts, Fast
P3 orchestrated print process, coupled with advanced light control, maximizes green strength and production speed.
Consistent part quality for parts with large or tiny features with exceptionally smooth surfaces every time.
P3 is built from the ground up, to enable the next generation of photopolymers to withstand the harshest conditions.
