In 3D printing, the bulk of each printed layer, regardless of complexity, is deposited by the same, rapid spreading process. [9] As with other powder-bed technologies, support structures are generally not required because loose powder supports overhanging features and stacked or suspended objects.
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
Import 3D models (oftentimes STL files from Thingiverse or user created in apps like Autodesk Fusion 360). The user can rotate and scale the 3D model to fit the virtual print bed. They can then convert the 3D model into G-Code that the printrbot can understand.
Computer-aided design (CAD) model used for 3D printing. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.
A slicer is a toolpath generation software used in 3D printing. It facilitates the conversion of a 3D object model to specific instructions for the printer. The slicer converts a model in STL (stereolithography) format into printer commands in G-code format. This is particularly usable in fused filament fabrication and other related 3D printing ...
Ultimaker is a 3D printer manufacturing company based in the Netherlands, with offices and assembly lines in the US. [1] They make fused filament fabrication 3D printers, develop 3D printing software, and sell branded 3D printing materials. [2]

The polyamic acid precursor to Kapton is mixed with an acrylate cross linker and photoinitiator that can form a gel when exposed to ultraviolet light during 3D printing. Subsequent heating of the 3D printed part up to 400 °C removes the sacrificial crosslinks and imidizes the part forming Kapton with a 3D printed geometry.
