Atomstack Cambrian 3D Printer Review

July 4, 2022

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.

Why Choose ATOMSTACK Laser Engraver ?
We are the official authorized distributor of ATOMSTACK. We have a professional technology team. We consider your needs, we spend a lot of time testing various Laser Engraver, just to show the best products. Hurry up and customize something unique for your family and lover!
Laser engraving is a popular option that provides a permanent and legible marking on an object through etching, ablation, or deep laser engraving. It is similar to laser marking, but the resulting appearance differs due to the depth of laser penetration.
Laser engraving is commonly used to create permanent serial markings on substrates made of: Metal, Wood, Plastic, Leather.
Benefits Of Laser Engraving Over Traditional Processes
Compared to manual engraving:
Minimally Invasive: Laser engraving can be performed at a range of depths without any direct contact at all. Surface marks can even be done on stainless steel with no depth. Overall, lasers are less damaging than manual engraving and keep the substrate material’s physical integrity intact.
Precise: Lasers provide a level of control that’s impossible to achieve manually. Compared to hand-engraving, the process is swift, clean, and highly repeatable, with little room for human error.
Versatile: A single laser engraving machine can be used to create a host of different designs with only minimal calibration. They can also produce exceptionally complex patterns. Affordable: On average, laser devices last longer than other engraving machines and require less maintenance, resulting in savings that can be passed along to the consumer.
Fast: Lasers can be programmed to render virtually any design in a matter of moments. Because the process is automated, it’s easy to scale production runs as needed according to demand.
Long-Lasting: Laser-engraved designs are permanent but can wear over time, depending on the substrate material that’s used. Soft metals, for example, may experience more signs of wear than hardwood. In general, however, laser-engraved designs tend to have a longer lifespan compared to other engraving methods.
