I was looking at some end high 3D printers (drooling just a little bit) when I found this.enter image description here

Now, this was a 3500 \$ printer when new back in 2016. I'm relatively to the 3D printing (well... kind of) and have not seen this type of design before. What is it? Cartesian? CoreXY? This style, from my limited knowledge, looks like a best of both worlds kind of scenario because if you look at it - it has that traditional simple Cartesian design, but with a light head of a CoreXY type printer (Exclude the circuitry behind the stepper, that is something else). This was designed to be used in a mechanical application, so it has to be precise. Is this a good configuration and does Marlin support it?

I'm can't say for sure, since this is my first time seeing this type of 3D printer configuration too, but I think this is a cartesian style printer. If you think about it, it is similar to a Prusa-style printer, but instead of an x-gantry being raised and lowered by a leadscrew, the heated bed is being lowered and raised with two leadscrews. Software-wise, the printer you mentioned should be configured exactly like a Prusa-style printer, but with a reversed Z-axis, since to make the heated bed move closer to the hotend, it must be raised instead of lowered.

I personally do not think this printer is a CoreXY configuration since a CoreXY printer relies on two motors that work simultaneously to move the X and Y axis, while the printer you showed has the X and Y-axis moving independently of each other (as can be seen by the belt under the heated bed and the belt that moves the hotend left and right). At least, in my opinion, the way the X and Y-axis operate on a CoreXY is what makes the CoreXY unique, instead of the raising and lowering of the heated bed.

You can read about the variations of Cartesian 3D printers here. If you are interested in other styles of 3D printers, you can check the Delta and Polar style printer section of this article.

Hope I piqued your interest in 3D printing :D

Feel free to comment on this if you have more things to ask, and I'll get back to you as soon as I can :)

  • $\begingroup$ This is correct. From the pic it's clearly cartesian. $\endgroup$ – R.. GitHub STOP HELPING ICE Jul 9 at 19:57
  • $\begingroup$ IMO this is a much better version of the traditional Cartesian. It has a lighter x-gantry which will reduce ghosting and speed up print time. Do you agree? $\endgroup$ – Faraz Ahmed Jul 9 at 20:24
  • $\begingroup$ and YES! is just like the Prusa! $\endgroup$ – Faraz Ahmed Jul 9 at 20:43
  • $\begingroup$ Do you mean carriage? The gantry doesn't move. But it's got a stepper on it (direct drive) so it won't be terribly light... $\endgroup$ – R.. GitHub STOP HELPING ICE Jul 10 at 0:17
  • $\begingroup$ Generally, to reduce vibrations of an operating printer, one should focus on reducing the mass of suspended moving parts. In the case of a Prusa printer, it has an X-carriage that moves around, but in the case of the printer you mentioned, it's more like it has a Z-carriage. Since a heated bed weighs more than a hotend, the vibrations will be more apparent on prints. (At least, this is how I imagine the design to function). As for print times, it is more heavily dependant on motor quality and the max extrusion rate of the hotend than the actual design of the printer. $\endgroup$ – Kiro Jul 10 at 0:37
