Materials » Polyamide

Models in polyamide are constructed from a white, very fine, granular powder. The result is a strong, somewhat flexible material that can take small impacts and resist some pressure while being bent. The surface has a sandy, granular look, and is slightly porous.

Pricing info

  • All designs that fit within a bounding box of 125 cm3 and have a maximum dimension of 200 mm comes at 12,5€ a piece.
  • If your design fits within a bounding box of 27 cm3 (for example 30 x 30 x 30 mm) and has a maximum dimension of 100 mm, you’ll only pay 5€ per copy of that same design (for example you’ll pay 32,5€ for 5 copies as 12,5+5+5+5+5 = 32,5)
  • For copies of any other design that still fits within the 125 cm3 and have a maximum dimension of 200 mm, you will pay 10€ per copy (for example, you’ll pay 52,5€ for 5 copies as 12,5+10+10+10+10 = 52,5)

Typical use

Polyamide can be used for complex models, concept models, small series of models (several copies of a model), lamps, and functional models. This technique allows the greatest freedom of design of all 3D printing techniques.

Technology

Selective laser sintering is used to build your design with this material. The models are printed layer by layer by a laser that draws thin lines in the powder, which melts and bonds it together in order to form a thin layer of the model. After a layer is printed, a new layer of fresh powder is spread over the surface by a roller. The printer has a print chamber that is heated to just below the melting point of the powder; the laser beam adds the extra energy to melt the powder, forming a solid model. After a print job is finished, the result is a big block of heated powder with the printed models contained inside.

Additional information

  • Polyamide is a material that is perfect for beginning-designers who want a well-priced model, a maximum freedom of creation, and who don’t want to be bothered with the limitations of the printing process.
  • Polyamide models are not suited for outdoor use as they absorb moisture. However, in some cases the material can be treated to make it watertight.
  • Be careful for models with large, flat surfaces or plates (<25 cm). When such a model cools down, it can deform. The deformation process is known as warping.
