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 have to enable supports, then Cura builds a kind of support structure below those areas. Normally the support can be removed easily after the print and you just have to do some cleanup on the surface.
To enable the support, just click the checkbox on the recommended settings page.

Enable the standard supports as Smithy says, or design your own custom supports into the model. Sometimes custom supports may be desirable in special circumstances: for example to make the support stiffer so you can more easily grab and pull it out with pliers, or to make it extend so you can grab it, or to make special holes in it to insert hooks.
Usually I prefer to design custom supports into my models, so I have full control. Except for large and easy to reach areas, where the standard supports do a very good job.
For example, the red and orange blocks below here are custom supports, to prevent the bridges of the yellow part from sagging too much, since the blue spoon has to slide through that yellow part. This part is too small to get in with a knife, so I need the supports to extend, so I can grab them. The supports also need a little bit of extra brim for stability. For reference: text caps-height is 3.5mm, text legs are 0.5mm. So, all this is very small.
Tha same one plus a few other types of supports I tested or used through the years:
Another one, if you don't want the support to go all the way down and damage the part below it.
Same, now also on the center bridge: the bottom of the support-bridge will sag and produce some "spaghetti", but the real bridge will be reasonably okay after some cleaning up.
The above one printed. Keep in mind the small dimensions: the "plates" are 1mm thick, the text is 3.5mm caps-height. Nozzle-diameter is 0.4mm.
And another one that could be usefull for springs or cylinders. The red support needs to be cut out later.
