Stacker S4 head storage rail

Updated: scroll down for the version in XT-CF20

The Stacker S4 is a fantastic printer. Tough, reliable and industrial grade. We are the distributor of this US made machine in Europe and have printed many hours on it. One of the big advantages of the Stacker printer is its versatility: You can print 4 prints at the same time or print one big print. But what to do with the other print heads if you don’t need them?

Simple: store them!


We printed this part, obviously, on the Stacker S4 with colorFabb_XT Light Gray. We used a 0.12mm layer height which resulted in a 16 hour print.

The head storage allows the use of the maximum print volume with the remaining print heads.

Stacker recently launched the Stacker S2 on Kickstarter. You can read more about this printer here. It is the smaller sibling of the S4 with a smaller build volume and two, instead of four, print heads. The technology is the same as the S4, which has already been tested and tried by the market for almost a year.

For functional materials in such an application, we do not look any further than our colorFabb_XT.

colorFabb_XT is made with Eastman Amphora™ 3D polymer AM1800. Launched in September 2014, it is a fantastic functional engineering material. With colorFabb_XT we achieved to produce a filament that provides good strength and toughness, as well as certain FDA food contact compliances. It has found a wide audience amongst users looking for extra functionality. With a temperature resistance of 75+ degrees, this filament offers (aside from its high strength and very high toughness) odor neutral processing, a styrene free formulation, FDA food contact compliance and BPA (Bisphenol A ) free formulation.

colorFabb_XT is available in various colors. We have released it in Light Gray (RAL 7035) and Dark Gray (RAL 7043) as well for the more functional looking prints.

Update: April 6th 2017

We made another version, but now in XT-CF20:

Of course this one was printed on the Stacker S4 at a 0.2mm layer height. The matte surface quality is just plain awesome as you can see and the look fits the industrial grade build of the printer perfectly.

XT-CF20 is our first Amphora based special filament, launched nearly two years ago, made with colorFabb_XT and 20% carbon fibres. More information can be found here. XT-CF20 has received some really good reviews on our website. It may not be the easiest filament to print with, but the results can be stunning. The functionality, stiffness and the matte finish are true selling points of this material.

XT-CF20 is available online.
