The proportion of these structures, known as 'infill density', is a key parameter that can be adjusted in the slicer. Support structure (in blue) generated by Cura software. Supports: Since most 3D printing processes build objects layer by layer, from the bottom up, each new layer is deposited directly on top of the previous one. Consequently ...
3D printing filament is the thermoplastic feedstock for fused deposition modeling 3D printers. There are many types of filament available with different properties. There are many types of filament available with different properties.
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.
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.
Robocasting (also known as robotic material extrusion [1]) is an additive manufacturing technique analogous to Direct Ink Writing and other extrusion-based 3D-printing techniques in which a filament of a paste-like material is extruded from a small nozzle while the nozzle is moved across a platform. [2]
The infill wall is the supported wall that closes the perimeter of a building constructed with a three-dimensional framework structure (generally made of steel or reinforced concrete). Therefore, the structural frame ensures the bearing function, whereas the infill wall serves to separate inner and outer space, filling up the boxes of the outer ...
Solid modeling software creates a virtual 3D representation of components for machine design and analysis. [11] A typical graphical user interface includes programmable macros, keyboard shortcuts and dynamic model manipulation. The ability to dynamically re-orient the model, in real-time shaded 3-D, is emphasized and helps the designer maintain ...
Its amorphous density at 25 °C is 1.27 g/cm 3 (.046 lb/in³). It is prone to stress cracking in chlorinated solvents . Polyetherimide is able to resist high temperatures while maintaining stable electrical properties over a wide range of frequencies.
