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.
Consider a basic calibration cube. It has 12 edges where one face meets an adjacent face. There should be no gaps in those edges. If there was a gap then if you tried too fill the cube with water it would run out onto the floor. The model isn't watertight (also called non-manifold).
When a slicer goes through the model it needs to know where the inside is and where the outside is. That gap in a seam allows the slicer to move along the wall on the outside and keep going through the gap instead of onto the outside of the adjacent face. Now the slicer is on the inside but doesn't know it. That's when all the confusion jumps up and the slicing goes wrong. That's why the warning comes up.
Even a "Respected Designer" is at the mercy of the software utility that converts a CAD model into an STL/OBJ/3mf file for use in the slicer. Designers themselves can put a model together incorrectly and cause problems during the export to STL.
Cura has some basic STL repair functions (if the Mesh Tools plugin is loaded from the MarketPlace). MS 3D Builder (in Windows) and Fusion 360 have decent repair tools as do some on-line sites (I've been using THIS ONE and it's pretty good. I like the report it generates on what was wrong with the model.)
A pretty fair percentage of the problems attributed to Cura both here and on the Ultimaker Github site are actually problems with the models. Of those problem models only a tiny percentage cannot be repaired without going back and fixing them in the CAD software. That FormWare site I mentioned fixed one model that had 36,000 errors. In that particular case I think magic was involved.
