Material
PA-GF
PA-GF blends polyamide powder and glass beads to offer all the advantages of regular polyamide, but with a much higher thermal resistance (up to 110°C). This material is ideal for functional prototypes and end-use parts that need high rigidity and tensile strength, and for demanding environments where temperature performance or wear resistance is key.

Finishing degrees
The right finish can transform your print into a product. Explore the post-production finishes we offer for this material. If you have any questions or special requests, get in touch with us.
Normal
- Loose powder removed
- Sandblasted
Sealing, standard
- Loose powder removed
- Sandblasted
- Treated with sealant that fills small pores
- Results in airtight/watertight parts
Color dyed
- Loose powder removed
- Sandblasted
- Parts are color dyed by being submerged in a bath containing color pigment
- Due to the unique nature of the laser sintering process, e.g. in terms of parameters, build position, and light deflection, color intensity may vary
- This finish is only possible for parts with maximum dimensions of 400 x 330 x 360 mm (black) or 150 x 150 x 150 mm (other colors: brown, purple, blue, petrol, green, bordeaux, red, orange, yellow)
Smooth
- Loose powder removed
- Sandblasted
- Parts are mechanically polished by being placed in a tumbler, together with pebbles, which then vibrates at a high frequency (for PA-GF this finish is only recommended for sturdy parts due to the brittleness of the material)
- This process only smooths the outside of your part; it is not possible to completely polish the inside
- As the polishing process removes 0.1 mm of material from your part, you should add extra wall thickness to avoid problems
- Small details and thin walls could be worn away and may even disappear
- Edges will be rounded and your part will become less ‘crisp’ once tumbled
- This finish is only possible for parts ranging from ±30 mm to 200 mm
Smooth + color dyed
- Loose powder removed
- Sandblasted
- Parts are mechanically polished by being placed in a tumbler, together with pebbles, which then vibrates at a high frequency
- (for PA-GF this finish is only recommended for sturdy parts due to the brittleness of the material)
- This process only smooths the outside of your part; it is not possible to completely polish the inside
- As the polishing process removes 0.1 mm of material from your part, you should add extra wall thickness to avoid problems
- Small details and thin walls could be worn away and may even disappear
- Edges will be rounded and your part will become less ‘crisp’ once tumbled
- Parts are color dyed by being submerged in a bath containing color pigment
- Due to the unique nature of the laser sintering process, e.g. in terms of parameters, build position, and light deflection, color intensity may vary between parts
- Colors will appear lighter than on parts that have not been tumbled
- Differences in smoothness (e.g. inside and inside of corners) may lead to some color variation
- This finish is only possible for parts ranging from ±30 mm to 200 mm
