According to some aspects, an additive fabrication device and a build platform suitable for use within an additive fabrication device are provided. The build platform may include a build surface on which material may be formed by the additive fabrication device when the build platform is installed within the additive fabrication device. According to some embodiments, the build platform may include a flexible build layer and at least one removal mechanism configured to be actuated to apply a force to the flexible build layer. Such actuation may cause the flexible build layer to deform, thereby enabling separation of material adhered to the build surface from the build platform. According to some embodiments, the build platform may comprise a restorative mechanism that acts to return the flexible build layer to a flat state so that subsequent additive fabrication may form material on a flat build surface.

Techniques for build platform part release in additive fabrication and related systems and methods

Washing apparatus and methods used to process additively fabricated (e.g., 3D printed) parts are described herein. The apparatus and methods may be used to wash uncured liquid resin from the parts. The washing apparatus may include two or more containers for storing respective solvents and may be fluidly connected to a vessel in which the additively fabricated parts are placed. One or more pumps and one or more valves may be controlled to introduce a first solvent from one of the containers into the vessel to wash the part in a first wash cycle and then the valve(s) may be re-configured to introduce a second solvent from another container into the vessel to wash the part in a second wash cycle. Advantageously, the parts may remain in the same vessel while being washed with both solvents in succession.
