In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!
The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
So what’s new?
The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
The UltiMaker S7 also includes quality of life improvements:
Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more
Curious to see the S7 in action?
We’re hosting a free tech demo on February 7.
It will be live and you can ask any questions to our CTO, Miguel Calvo.

Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
If you have Cura 4.13.1 there is a printer definition file for the A20M. I don't know how many versions back it was included.
As for a Settings Profile I think you will need to build your own. As I recall that is a 2-in-1-out hot end. In the Cura Marketplace (button at the top right) there is a plugin "Printer Settings". Install it and after restarting Cura it will show up at the very bottom of the settings list. Within Printer Settings are "Extruders Share Heater" and "Extruders Share Nozzle". You will need to select both of those.
Next to the Settings Search box is the Visibility icon. Click on it and set it to "All".
I would practice with Extruder 2 disabled and print a couple of test cubes. When those start to look good then re-enable extruder 2 and disable extruder 1 and slice and print again. Get them both dialed in.
I don't own a multi-extruder machine but I've played with virtual ones in Cura. The retraction distances when switching from one extruder to another, the size of the purge tower, how much material you actually need too purge to switch colors (white is tough) need to be practiced.
There are settings within the Dual Extrusion section of Cura you will need to become familiar with. In addition, each extruder can have separate starting Gcode that would be added at each tool change.
You're right - it isn't simple and there is no "Easy" button. Maybe someone over on Reddit has a profile you can start with. There haven't been many A20M owners who have shown up here. Good Luck.
