FreeFoam resins are 3D printed similar to other photopolymer resins using DLP. After 3D printing, FreeFoam parts can be expanded on-demand during a brief heating cycle in an oven at approximately 160-170°C (320-340°F). The printed parts contain dispersed heat-activated foaming agents that create closed cell pores inside the material. This highly controllable process causes FreeFoam resins to consistently expand 2 to 7 times their as-printed sizes depending on the grade of resin, ach
