Systems and methods for an improved peel operation during additive fabrication

According to some aspects, a method of additive fabrication wherein a plurality of layers of material are formed on a build platform is provided. The method may comprise forming a layer of material in contact with a container, and subsequent to the forming of the layer of material, rotating the container relative to the build platform and moving the build platform relative to the container, thereby creating an effective fulcrum about an axis, wherein the rotating of the container and moving of the build platform causes the layer of material to separate from the container. ... Formlabs Inc

Multi-material separation layers for additive fabrication

According to some aspects, a container is provided for use in an additive fabrication device configured to fabricate parts by curing a liquid photopolymer to form layers of cured photopolymer. The container may comprise a laminated multi-material layer having an elastic first layer that aids in separation of cured photopolymer from the container in addition to a barrier layer on an upper surface that protects the first layer from exposure to substances in the liquid photopolymer that may not be compatible with the material of the first layer.. ... Formlabs Inc

Techniques for metallic material deposition in additive fabrication and related systems and methods

According to some aspects, a method is provided of forming a metallic object via additive fabrication, the method comprising obtaining a geometric description of a first object with an exterior surface, generating a geometric description of a second object, the second object bounded by the exterior surface of the first object and having one or more voids, fabricating said second object via additive fabrication based on said geometric description of the second object, and depositing a metallic material onto said second object, wherein the metallic material is deposited into said voids of second object.. . ... Formlabs Inc

Techniques for reducing differential cure artifacts for additive fabrication and related systems and methods

According to some aspects, techniques for reducing time-dependent fabrication artifacts in additive fabrication are provided. By selectively activating and deactivating an element of an additive fabrication device that forms solid material, adjacent regions of material may be formed sequentially, thereby reducing time-dependent fabrication artifacts at the cost of increasing the time taken to fabricate an object. ... Formlabs Inc

Position detection techniques for additive fabrication and related systems and methods

According to some aspects, techniques for determining a position of a build platform in an additive fabrication device are provided. According to some embodiments, forces resisting separation of the build platform from an opposing surface are measured and a position of the build platform with respect to the opposing surface is determined. ... Formlabs Inc

Systems and methods of flexible substrates for additive fabrication

According to some aspects, a method of additive fabrication is provided wherein a plurality of layers of material are formed on a build platform, the method comprising forming a layer of material in contact with a substrate and further in contact with either a previously formed layer of material or the build platform, the substrate being an actinically transparent, flexible, composite material, and subsequent to the forming of the layer of the material, actively separating the layer of material from the substrate.. . ... Formlabs Inc

Techniques for additive fabrication process optimization and related systems and methods

According to some aspects, a method of additive fabrication is provided wherein a plurality of layers of material are formed on a surface of a build platform, each layer of material being formed so as to contact a container in addition to the surface of the build platform and/or a previously formed layer of material. The method comprises forming a layer of material in contact with the container and in contact with a previously formed layer of material, and subsequent to the forming of the layer of the material, separating the layer of material from the container by simultaneously applying a first force to the layer of the material in a direction perpendicular to the surface of the build platform, and a second force to the layer of the material in a direction parallel to the surface of the build platform.. ... Formlabs Inc

Techniques for surface preparation during additive fabrication and related systems and methods

According to some aspects, an additive fabrication device is provided configured to form layers of material on a build platform, each layer of material being formed so as to contact a container in addition to the build platform and/or a previously formed layer of material. The additive fabrication device may comprise a container and a wiper, wherein the wiper comprises a wiper arm and a wiper blade coupled to said wiper arm using a pivoting coupling.. ... Formlabs Inc

Techniques for fluid sensing during additive fabrication and related systems and methods

According to some aspects, an additive fabrication device is provided comprising a container removably attached to the additive fabrication device, and a detector configured to sense a fluid level of photopolymer resin within the container, wherein said detector does not contact said container.. . ... Formlabs Inc

Techniques of additive fabrication using an aspheric lens and related systems and methods

According to some aspects, an additive fabrication device for forming solid objects within a build region is provided, the device comprising a laser source, an aspheric lens configured to receive light emitted by the laser source and to produce a light beam having a circular cross section at at least one position inside the build region, and at least one mirror configured to be actuated to reflect the light beam toward a selected position within the build region.. . ...
