This machine promises the user an incredible TPU, or not I mean TPR, which are soft rubber filaments. It sounds like a cool app, but it's probably not the first thing most of us look for when buying a 3D printer.

Atomstack takes this into consideration and offers a 1.75mm extruder for regular FDM filament! So you get 2 extruders, a 1.75mm FDM extruder and a 2.85mm TPR extruder. Interesting, let's see what they promise.

Outstanding Features of the Cambrain Pro 3D Printer

The whole selling point of this 3D printer is its rubber TPR (thermoplastic rubber), which seems to be a version of TPU that is better in terms of elasticity, meaning you have more rubber drops than regular TPU.

Extrusion of soft filaments has traditionally been difficult because they wanted to avoid every opening in the machine. Since the material bends, it is difficult to control the motion and you have to know its material properties to create a profile that will print as expected.

Atomstack Cambrian tried to solve this problem by making a dedicated TPR extruder that handles soft materials in the best possible way, making it easier for you as a user.

Of course, you don't want to be limited to soft materials, which is why the Atomstack Cambrian also comes with a 1.75mm standard FDM extruder for your normal filament, which is a great solution to that problem!

Although the Atomstack Cambrain 3D printer appears to be a generic frame construction that we've seen in many printers around, it does promise some easy assembly and added functionality.

For example, the LCD touch screen looks beautiful and the Z axis of the dual screws/motors feel important!

The bed is also lattice glass and of course can be heated.

I must point out that the flat cable running on the machine is not something I trust. I have a bunch of these wires that break or fray quickly.

Why choose soft TPR filament?
Creativity is of course the only limit to printing soft materials. Atomstack seems to think you'll use its TPR filament to print shoe designs, footwear, medical shoe implants, and other products.

I guess it's a debate about what you're actually printing. Let me know below if you have any ideas!

One really cool thing is that the Atomstack Cambrain promises great lattice 3D printing, and the superior control of the TPR filament might actually deliver just that.
