Abstract
In some embodiments, the techniques described herein relate to photoreactive 3D printing systems and methods. The 3D printing system can include: a moveable print platform; a resin tub with a membrane; resin contained within the resin tub; an illumination system; a force sensor, and a print recipe including information for layers in a 3D printed part to be built on the print platform. The photoreactive 3D printing system can be configured to: project an image through the membrane into the volume of resin using the illumination system; move the print platform in a z-direction; measure a force on the print platform using the force sensor, and update a print platform movement in the print recipe during a printing run based on the force on the print platform.
