3D printing is the process of creating three-dimensional objects from a digital design.
This is done through the process of additive manufacturing which creates three-dimensional objects one layer at a time. Using an extruder, the 3D printer will heat up a material (filament) and melt it. Each layer then bonds to the previous layer slowly forming an object. Watch the short video below to learn more about 3D printing:
Common parts of 3D printers:
Build Plate: Foundation on which prints are built. Also known as, print bed or heated build plate.
Extruder: Heated unit that melts filament. Also known as, print core or hot end.
Filament: Material that is melted, then bonded to create a 3D object.
Control panel: A user interface to select machine options. Also known as, display unit.
Guide tubes: Tubes that house filament and direct it from a spool and into the extruder. Also known as, Bowden tubes, direct drive (if none)
Nozzle: The part of the extruder that deposits the filament on the build plate.

There are a variety of different filaments that 3D printers can use. Below are just a few common filament types, their properties, and pros and cons.
PLA (Polylactic Acid)
PLA is probably the most popular type of filament used in 3D printing as it is easy to print with and is more environmentally friendly than other types of filament.

Tough PLA (Polylactic Acid)
Tough PLA’s impact strength is closer to ABS than regular PLA. This means your 3D printed parts can be used for more functional applications, such as jigs, fixtures, and tools.

Pros
- Intricate curves, fine details, and overhangs |
Cons
|
TPU 95A (thermoplastic polyurethane)
TPU 95A (thermoplastic polyurethane) is a flexible material, making it ideal for applications that demand chemical resistance and the qualities of rubber and plastic.

Breakaway
Breakaway support is easy and quick to remove. It leaves behind a smoother quality finish than other support materials, with no further post-processing needed.
