3D printing

Creating a physical object from a 3D model. 3D Printing technologies include many different methods of creating objects with FFF (Fused Filament Fabrication) currently being the most popular for residential hobbyists and consumers.

Open Source

A development model promoting universal access to a product's design, production, software and other aspects. Redistribution of the product's design is encouraged. This model allows anyone to use and contribute to the product with the expectation that any improvements will be redistributed with the project. Many different licenses exist for Open Source software to protect the model of redistribution, availability and usage in commercial products.


When printing an object a raft is sometimes used to improve the adhsion of the object to the printer bed. Rafts can also be used to compensate for uneven print surfaces. When printing with supports a raft can be useful to stabilize the model and supports.

A servo is an electric motor with a feedback mechanism (usually a potentiometer) that can be used to position the motor. Hobby style servo motors are prone to having their plastic gears slip as well as developing jitter over time. Servos need to be occasionally recalibrated for the best results.

A resistor that reduces in resistance when heated. The properties of thermistors aid in controlling the heat in the heat block of an FFF printer by providing a feedback loop to the electronics of the printer which controls the heater cartridge.
