Three-dimensional printing, commonly called 3D printing, is a form of additive manufacturing in which physical objects are built layer by layer from digital files. The term "additi...
The most common 3D printing material is PLA, or Polylactic Acid, a biodegradable thermoplastic derived from corn starch or sugarcane that is prized for being easy to print, typical...
The flat surface where an object is built is called the bed, and how well the first layer sticks to this build plate, known as bed adhesion, is one of the most critical factors in...
Many of the variables a user can tune control the trade-off between speed, strength, and surface quality. Layer height sets the thickness of each printed layer, with 0.1 to 0.3 mm...
Before a 3D model can be printed it must be sliced, meaning converted by software into printer instructions written in G-code, the instruction language shared by CNC machines and 3...
Even with a good profile, tuning a printer to its environment is often necessary, and this process is called calibration. Flow rate calibration, which tunes how much filament is ex...
3D printing involves heat, moving parts, and chemicals, so safety deserves real attention. FDM printing melts plastic at high temperatures, and the resulting emissions of ultrafine...
Beyond hobbyist use, 3D printing has become an industrial tool for prototyping, jigs, fixtures, and end-use parts in fields as varied as aerospace, where lightweight components and...
