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.
First of all be very careful when rotating these parts now as brass is not nearly as strong as steel.
Only rotate these parts when the heater block is heated to around 180C so that any plastic in there will not act as "loctite". No need to go hotter than 180C as that can turn PLA and ABS into a kind of caramelized glue if you leave it hot for hours but 180C is pretty safe.
Teflon tape is fine. It has a glass temp of around 250C but it should be fine up to even 300C as a thread lock so the answer is "yes".
It may be that you didn't quite assemble it correctly. Your nozzle should not be touching the aluminum - there should be a very tiny gap - maybe 1/2mm such that you know for sure that the brass nozzle is touching the brass threaded pipe.
Years ago (more than 2 years ago), Ultimaker used to supply about 1 meter of ABS filament with the kit. The idea as to initially print with ABS such that the ABS would leak out through the heaterblock and nozzle. This would help clog up any leaks. Then I'm guessing you follow that with some PLA at "low" temperatures - no hotter than 220C I would think. After printing 40 hours of PLA like that the ABS should turn into a kind of glue. But I never had to do this.
If the leak is slow enough, eventually the PLA will cook into a glue and the leak will stop. After 5 or 10 hours of printing.
