Machine clamp

As we have seen before, 3D printing can be used in many production companies to create machine clamps. By using the right filament (and printer) it is easier, faster and cheaper than ever to optimize a production line so it suits your needs. Whereas 3D printing already has proven itself to shorten the prototype stage during product development, in production it can also bring down time to market and costs, while also adding more flexibility in the process.

This machine clamp was designed by our colorFabb team as a demonstrator during the recent Brabantse Metaaldagen, a tradeshow for the metal industry where we had a stand to demonstrate the added value of FDM/FFF 3D printing for various industries.

The clamp was printed on the Ultimaker 2+ using our PA-CF Low Warp with 100% infill. Print settings:

  • Printing temperature: 260C
  • Print speed: 35mm/s
  • Heated bed: –

We printed with a 0.2mm layer height.

About PA-CF Low Warp

PA-CF Low Warp was launched a little over a year ago. It is a one of a kind polyamide formulation with the ability to print nearly warp free on non heated buildplatforms. PA-CF Low Warp excels in tensile and impact strength and allows continues use at 120°C while retaining sufficient mechanical properties.

The material can be printed on desktop FFF 3D printers, which have a temperature range of at least 260°C on the hot-end and the ability to mount an abrasive resistant nozzle. The formulation has been modified to reduce uptake of moisture and it also takes about 4 times longer to reach the saturation point compared to unmodified PA6. This makes PA-CF Low Warp less affected by moisture then most other nylon filaments available in the market.



The material shows good results when printed at ambient temperature, or cold bed. The advised processing temperature for this material is set between 260C and 280C. You can find more information about the printability of PA-CF Low Warp on our dedicated landing page.

A special point of attention is the abrasive nature of the carbon fibers. In general these fibers will accelerate the nozzle-wear of brass nozzles, much faster than unfilled filaments. ColorFabb recommends to using wear resistant nozzles, such as E3D hardened steel nozzle or Olsson Ruby nozzle.

PA-CF Low Warp is available now and ships on spools containing either 700gr of 2kg of filament. Click here to go directly to our webshop.

“The Visitor” in copperFill

The Ultimaker forums are a great place to find cool prints and sometimes we come across a fantastic print made with one of our materials. This week we found Frederiek Pascal’s print of “The Visitor” printed with copperFill on an Ultimaker Extended 2+ and post processed. Post-processing happened manually with steelwool and copper cleaner, which resulted in a perfect result!


The settings used were:

Nozzle diameter: 0.40 mm

Layer resolution: 201-250 micron

Print time: 8-12 hours

Temperature: 205˚ C

Speed: 40 mm/s

Shell thickness: 1.6 mm

Height: 250 mm

B/T thickness: 1.2 mm

Fill density: 20 %

Frederiek updates his Instagram account regularly with his latest prints:

copperFill is one of the metal based filaments colorFabb has released. Presented to the world in the fall of 2014 we have seen stunning results with copperFill, with Frederiek’s print being one of them. You can find out more about working with copperFill and post-processing other metal filaments here:

copperFill is available in both 1.75mm and 2.85mm and in two weight varieties: 750 grams and 1500 grams.
