PLA

Biodegradable and non-toxic, PLA is the filament of choice for most people. Extruding at temperatures between ~190-230C, PLA does not require a heated print bed to successfully adhere to the build plate. If you choose to use a heated print bed, PLA adhere best at temperatures between 60C and 80C.

The best thing about PLA is how versatile it is. PLA is used to make wood, metal, glow-in-the-dark, and many other hybrid filaments.

Properties

Medium strength and durability
Fairly brittle
Easy to work with
Non-toxic with a pleasant smell

ABS

ABS is often used when printing working prototypes or functional parts. That’s because it’s a bit more flexible and durable than PLA, and can better withstand sunlight and moisture exposure. ABS prints at pretty high temperatures around 210-250C, and requires a heated print bed at around 60-110C.

Properties

Highly durable and impact resistant
More flexible than PLA
Can sometimes be tricky to print with
Strong chemical odor

Properties

More flexible than either ABS or PLA
Good durability
Easy to print with
Recyclable

Nylon

Nylon is a high-temperature filament that results in a highly durable and flexible models. In fact, it would be the perfect filament if not for its tricky print conditions. Most nylon prints at temperatures between 240-260C, and requires a controlled environment with a heated print bed set around 50-100C.

Properties

- Extremely strong, durable, and flexible
- Great filament for outdoor objects
- Tricky to print with

TPU

TPU is a flexible filament that is easier to print with than most other flexible filaments due to its firmer consistency. TPU produces durable, rugged prints that are still flexible and bendable. For best results, print with this filament at slower speeds below 30mm/s. Set the extruder between 220-240C and the print bed around 60C.

Properties

- - Produces rubbery, flexible prints
  - High durability and heat resistance
  - Uses for both industry and consumer prints
  - Relatively easy to print with
