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.
Pretty good. I'd be happy with that. But there are a few things you can improve. The thing that bothers me the most about this print is those horizontal lines.
That could be temperature fluctuations but if so it should be obvious by watching the temp while it prints it would have to fluctuate 10C. More likely it is the Z axis.
What kind of printer is this? Does it have one z screw? two? If the printer is less than a month old then you probably have a crappy z screw, or z nut, or bearings. If it's older than a month then hopefully the z screw is just dirty and needs cleaning.
What is happening is that Z movement is inconsistent. You sliced for .15mm layer height but the Z is moving too far sometimes and other times not far enough. On times when it doesn't move far enough you get overextrusion because there isn't enough room to put all that filament in a layer that is say .05mm thick but enough filament for .15mm thick. So you get a layer that sticks out. When the Z moves too far you get underextrusion but it doesn't look as bad. It's still there though.
If this is a new printer and it's not an ultimaker you might need to replace some or all of linear bearings, z screw, z nut to some higher quality parts. These are not expensive parts.
