3D printing involves a variety of thermoplastic and resin materials that are used in the various 3D printing technologies. Each material has its own unique properties and characteristics that make them suitable for different applications. Here are some of the most popular 3D printing materials:
PLA (Polylactic Acid):
PLA is a biodegradable material made from plant sources such as corn kernels or sugar cane.
It is easy to print and does not require a heated printing platform.
It has low toxicity and a pleasant sweet aroma during printing.
It is suitable for prototyping and decorative products.
ABS (Acrylonitrile Butadiene Styrene):
ABS is an extremely durable and impact resistant material.
Requires a heated print bed as it tends to warp on cooling.
It is ideal for functional prototypes and parts such as covers, electronics housings and more.
PETG (Polyethylene Terephthalate Glycol-Modified):
PETG offers a combination of strength and impact resistance combined with an easy-to-print material.
It is moisture resistant and suitable for parts that will be used outdoors.
It is suitable for making functional prototypes and objects for the home.
TPU (Thermoplastic Polyurethane):
TPU is an extremely flexible and elastic material.
It is suitable for making flexible springs, rubber seals, accessories, etc.
It requires special print settings as it is more difficult to work with than solid materials.
UV Resins (Polymer Resins):
UV resins provide high detail and a smooth finish to models.
They are used in resin printer technologies (SLA, DLP, LCD).
They are suitable for printing precise and complex models, such as prototypes, art models, dental and medical applications.
ASA (Acrylonitrile Styrene Acrylate):
ASA is a similar material to ABS, but offers better resistance to weathering and UV rays.
It is suitable for making objects that will be exposed to sunlight and external conditions.
Nylon (polyamide):
Nylon filament provides great strength, impact resistance and flexibility.
It is suitable for making mechanical parts, springs and parts with complex shapes.
These are just some of the materials used for 3D printing. There are others such as HIPS, PC (polycarbonate), PVA (water soluble material) and more. Each material has its own advantages and limitations that must be considered when choosing the most appropriate one for the particular task.
