This thread is dedicated to 3D printing and other small-scale manufacturing processes such as CNC machines, miniature foundries, resin casting, and many others.
The major types of 3D printers available on the average Anon's budget include:
Fused Deposition Printers:
These printers print layer by layer using plastic filament (usually ABS, PETG, or PLA). If these plastics are reinforced with fibers (usually glass, carbon fibers, or wood) these prints can be quite strong. However there is an issue of accuracy with fused deposition printers because the plastics used tend to shrink as the cool so high precision parts are out of the question. Ender and Anet make great and affordable printers for beginners.
Resin printers:
Resin printers can print using a variety of resins that can have plastic, wax-like, or even rubbery characteristics. These printers are much more accurate than fused deposition printers and good for producing high precision parts or molds to produce high precision parts. They are a little more pricey than fused deposition but they are still very affordable.
Clay printers:
These can print using ceramic clays or even metal clay. These are best used for producing sturdy parts that do not need a high degree of accuracy as metal clay and ceramics will shrink in the kiln.

A secret technique to improve the strength of your plastic prints is to electroplate your prints. You can just about double the strength of a 3d print by electroplating it.
If electroplating isn't enough you could always use the print as a mold for a stronger material such as resin or metal. The Devil's forge on Amazon is a great product for back yard casting.
If 3D printing isn't your style there are plenty of CNC machines that are very affordable that can machine plastic, wood, or even small aluminum parts.
