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.
The Maximum Accel for Creality printers is usually 500 and the Jerk 8. I generally print PETG at 35 with the outer walls at 30. Keeping the outer wall speed lower helps abate the bouncing around corners.
In that photo you can see on the right edge that the printer bounced going around that corner as well. If you lower the Accel too much you might have problems going into a corner as the extrusion will stop farther from the corner. Maybe a small chamfer on the holes would help.
Part of this is the printer (any printer) as the belt tension and any slop in the mechanicals always show up in a print. As I recall, the belts on the Ender 5 are pretty long. It doesn't take much stretch on starts and stops to cause a little bump like that.
On another note - you might have some under-extrusion going on. I print a lot of PETG on my Ender 3Pro as most of my stuff is functional prints and the finish looks a lot different than that one.
Here is a PETG print and you can see a bit of ringing as it came around the corner on the right, and then again after the left hole. In my case I know it's the printer. That's about as good as I can tune it. (The rough edge on the top radius was where the support was.) The print speed was 35, outer walls at 30, 0.4 nozzle, 0.2 layer and 0.4 line width, 240 hot end, 80 bed.
