PLA is the safest material to use in your 3D Printer. It is made from entirely natural substances such as maize and sugarcane.
When it is heated, PLA gives off a non-toxic chemical called Lactid.
Natural PLA is made from corn and is generally considered safe to use with food.
Acrylonitrile Butadiene Styrene
3D printing with ABS filament, a heated printing surface is recommended, as ABS plastic will contract when cooled leading to warped parts
Thermoplastic polyurethane
The material appears rubber-like, which means it can be extremely flexible, durable and smooth to the touch.
it has many important properties such as elasticity, transparency, and resistance to grease, oil, and abrasion.
It is unique due to its extremely flexible nature. Technically TPUs are made up of thermoplastic elastomers
Copper
Copper Fill is made of real copper particles and PLA so it works with desktop 3D printers. copper filament is perfect for a rustic finish.
Wood
It’s a mix of recycled wood fibers and polymer binders that can be melted and extruded just like any other 3D printer filament.
Parts printed with Laywood have about the same properties as partsprinted with PLA filament
Wood-based filaments are typically a composite that combines a PLA base material with wood dust, cork, and other powdered wood derivatives
This filament is also less abrasive compared to other composite filaments such as carbon-fiber filled and metal filled, since wood particles are much softer.
Carbon Fiber
Carbon fiber filaments is the stronger, sturdier, and more dimensionally stable versions of their base material.
It is an exciting filament to work with as it is perfect for making parts for prototypes and other applications. 1 How Carbon Fiber Is Used In 3D Printing
