Beschreibung
Zusammenfassung:	In some embodiments, a photoreactive 3D printing system includes: a moveable print platform; a resin tub comprising a membrane; a tension apparatus; a volume of resin contained within the resin tub; an illumination system; a print platform force sensor; and a print recipe comprising information for layers in a 3D printed part to be built on the print platform. In some embodiments, the photoreactive 3D printing system is configured to: project an image through the membrane at a polymer interface using the illumination system; moving the print platform in a z-direction; apply a tensioning force using the tension apparatus to induce a membrane tension on the membrane; measure an amount of print platform force using the print platform force sensor; and update the print platform movement in the print recipe during a printing run based on the amount of print platform force measured by the print platform force sensor.
