FDM
3D printing

FDM is the most widely available 3D printing process, mainly used for low-cost prototyping and design verification with very fast turn around times.

Benefits and Limitations

Low-cost
Fast turnaround times

Limited dimensional accuracy
Print layers are likely to be visible

FDM PLA Materials

High stiffness, good detail, affordable.

Standard PLA

PLA (FDM) is used for low-cost, non-functional prototyping. Offers greater detail than ABS, but is more brittle. Unsuitable for high temperature applications.
