3D Printing Filament

3D Printed Parts are Widely used for:

  • Prototypes
  • Concept models
  • Master patterns
  • Jigs and fixtures
  • Low volume production parts

Characteristics of 3D Printed Parts:

  • Complex geometries with no tooling costs
  • Wide range of materials and colors
  • FDM (fused deposition modeling) printed parts tend to be more durable compared with parts manufactured using other 3D printing technologies

Common Brands:

  • Toner Plastics



3D Printing Filament

Individually wrapped 1kg spools of 1.75 mm and 2.88 mm diameter 3D filaments for durable plastic parts

FDM (fused deposition modeling) 3D printing involves feeding a spool of plastic filament into a heated die, where it is melted and extruded onto a build platform. Successive layers of plastic material are deposited onto previously created layers to manufacture a three dimensional part. The part is then removed from the build platform and it can be sanded and painted as required.

3D printing is used to manufacture prototypes, jigs, assembly fixtures, and other durable plastic parts. It is a particularly useful process for making low volume parts when design flexibility is desired and/or the part geometry does not lend itself to injection molding or machining.

Curbell Plastics supplies a number of different types of 3D filaments. They are all manufactured to tight dimensional tolerances and they are engineered to have consistent processing characteristics when run through 3D printing machinery. All of our 3D filament materials are available in 1kg spools, which are individually wrapped to protect them from moisture and contamination. Filaments are available in 1.75 mm and 2.88 mm diameters in a number of different colors. Each type of filament has certain advantages. Compare material properties on the Typical Properties of 3D Printing Filament chart below.

3D PRINTING FILAMENT OPTIONS

ABS (Acrylonitrile Butadiene Styrene)– ABS is a low cost, durable material with exceptional toughness and impact strength. ABS is easy to paint and it is easy to assemble with adhesives and solvent cements. The surfaces of 3D printed ABS parts can be “smoothed” by exposing them to certain solvents. ABS has exceptional 3D printing characteristics and it is easy to process through many types of 3D printing machinery.

ASA (Acrylonitrile Styrene Acrylate)– ASA is different from many other polymers in that it has exceptional UV stability. It is often specified for models and prototypes that are intended for outdoor use.

HIPS (High Impact Polystyrene)– HIPS is a durable polymer material that is often used to create dissolvable support structures during 3D printing. In this application HIPS serves as a three dimensional support for other 3D printed materials. After the part is manufactured, the HIPS supports are dissolved using a solvent (typically Limonene) that does not attack the polymer that was used to print the finished part.

PETG (Polyethylene Terephthalate, Glycol-Modified)– PETG is a transparent polymer with outstanding 3D printing characteristics. It is often used for applications where fine detail, dimensional accuracy, and outstanding layer adhesion are required. Although PETG is naturally transparent, 3D printed PETG parts will not appear transparent since visible light will be diffracted and diffused at the interface between printed segments.

PLA (Polylactic Acid)– PLA is a low cost material with exceptional strength and stiffness. It is among the easiest materials to process on 3D machinery. PLA is preferred by many users because it tends to have a milder smell during 3D printing compared with many other types of plastic filaments. PLA is somewhat brittle so it should not be used for applications where parts may be subjected to impact. PLA is generally used for room temperature applications. It should not be used for applications where parts are exposed to elevated temperatures.

TPU (Thermoplastic Polyurethane)– Thermoplastic polyurethane is a tough, elastic material that is used when 3D printed parts need to be flexible and durable. TPU parts are used for a wide range of applications such as prototype cell phone cases and footwear when some degree of flexibility is required.

The properties chart above shows typical properties for each polymer that Curbell offers as an FDM 3D printing filament.

*Mechanical property values not in parentheses were generated using test specimens manufactured via FDM printing. Mechanical property values in parentheses were generated using test specimens manufactured via injection molding.

It is important to note that the actual property values for an FDM 3D printed plastic part may vary significantly depending on the machine settings and the direction (X, Y, or Z axis) in which the test specimen is manufactured.
