Some Common Plastic Materials Used in CNC and 3D Printing Process
In both plastic CNC machining and 3D printing, different plastic materials are used to meet different requirements, including strength, durability, flexibility, and heat resistance.
Common Plastic Materials Used in CNC Machining:
Acrylonitrile Butadiene Styrene (ABS):
Widely used for its impact resistance and toughness. Often used in automotive parts, electronic housings, and consumer goods.

Has excellent chemical resistance and low friction. Used in applications such as containers, packaging, and parts in the food industry.
Common plastic materials used in 3D printing (FDM/FFF, SLA, SLS):
Polylactic acid (PLA):
Biodegradable and easy to print. Often used for prototypes, hobby projects, and consumer goods.
Acrylonitrile butadiene styrene (ABS):
Excellent strength and heat resistance. Used for functional prototypes, automotive parts, and electronics housings.
Polyethylene terephthalate glycol (PETG):
Combines the benefits of PET and ABS with excellent strength, chemical resistance, and ease of printing. Good for mechanical parts and containers.
Resins (SLA/DLP):
SLA and DLP printing use different types of resins for high-definition, high-resolution printing with different properties such as flexibility, toughness, and transparency.
Polyamide (nylon):
Used in selective laser sintering (SLS) due to its strength, durability, and abrasion resistance. Ideal for functional prototypes and end-use parts.
These are just a few examples of common plastic materials used in CNC machining and 3D printing processes. The choice of material depends on the specific requirements of the part, including mechanical properties, surface finish and application.
