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.
You should never print something if it doesn't look right in layer view. That would have saved you a lot of time and it will save you lots of time in the future. ALWAYS look at the part in layer view before printing it.
The basic problem is that this part isn't manifold. A manifold parts has a connected 3d surface and a clear "inside" and "outside" where the "inside" is where you print filament and the "outside" is where you don't. This part is not manifold or possibly some of the wall normals are backwards which tell each triangle in the stl which side of the triangle is "air" and which side of the triangle is "solid". Examples of non-manifold are confusing (to cura) extra walls/triangles *inside* the print or missing walls.
The simplest thing to do is to just run it through the free netfabb repair service here:
To learn a little more about manifold you could try looking at the part in xray view. Anything that appears in red needs to be fixed.
Another option is to go into cura expert options and look at the 4 "fix horrible" checkboxes and play with those. There are 16 ways to check those and one of those 16 ways (or a few of them) are likely to fix this print.
If this is your own design (I'm pretty sure it isn't) and it was created in sketchup I can point you to a sketchup guide that has a few simple tricks to make sure your parts are manifold.
