With dual nozzle printers come great possibilities. Two colors, two different materials even. And what if we had a great support material? And what if we already happen to have such a material in our current portfolio? In between moving our entire company our print lab team started testing with using nGen as a support material for colorFabb_XT. A first test resulted in easy break away support with minimal scarring on the model.

For this test we used the GrabCAD’s Drill Case, which was originally designed for injection molding.

We used the dual nozzle Ultimaker 3 with 0.2mm layer height for this print. The surface finish of the colorFabb_XT is fantastic.

Printing a part designed for injection molding is challenging. But with the right settings and some material experimentation we got a great result. To all designers and engineers modeling for injection molding: checkout what you can do with an Ultimaker 3 and colorFabb materials. These results give much more freedom for designing for 3D printing and using functional materials for the best results.

We launched colorFabb_XT over 2 years ago at the London 3D Print Show together with Eastman Chemical Company. Eastman is our material partner for co-polyesters. colorFabb_XT is made with Amphora AM1800 and has a unique formulation for 3D Printing that features excellent properties : High strength and very high toughness, Odor Neutral processing, High Tg / improved temp. resistance, Styrene free formulation, FDA food contact compliance, BPA (Bisphenol A ) free formulation. It will allow the user to produce 3D printed functional products in a safe way.

nGen has proven itself to be a very versatile material that can be used for a lot of applications and now being a support material is one of them!

nGen is an all-round filament which has many advantages over PLA. The temperature resistance is over 80 degrees C and it works on most printers with a heated build plate.  nGen is a low-odor, styrene-free material uniquely suited for 3D printing enthusiasts, particularly those who need the flexibility to print within a wide processing temperature range. With nGen you will have good flow properties through the printer nozzle—even at lower temperatures than some other polymers require. These properties make nGen more workable at a wider breadth of temperatures, producing reliable results and resulting in less waste. You can find more information on our dedicated landing page.

Both colorFabb_XT and nGen are made with Eastman Amphora™ 3D polymer. With Amphora, items can be created that are more functional, more durable, more efficient, and attractive.


Both nGen and colorFabb_XT are available in our webshop. You can find more information about co-polyesters in general in last year’s blog. Below is a handy chart which explains the differences between the rigid co-polyesters in our current portfolio:

  1. Did you use standard break-away support structures for the nGen or the contact support structure type as you would use it for e.g. water soluble support materials?

    • Standard brake-away support.
      Not sure about the exact settings but we generally prefer a zig-zag pattern support as it’s quite easy to remove.

  2. How was the nGen used as support material? Was it dissolved?

    • The nGen support broke away fairly easily, all we did is break it away with some pliers.

  3. This is nice piece of information. I just wanted to know the process of removing the support material. Does nGen makes the breakaway support or do we need some process to remove it?

    • The nGen support broke away fairly easily, all we did is break it away with some pliers.
