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.
This is probably the #1 reason why people go to dual extruders.
I would go about the supports on those a little differently (like normal instead of tree) but that's just personal preference. If you increase the floor distance then an interface can be a lot easier to remove. It will look kind of sloppy, but so what - it's all getting thrown away anyway. Try setting the Floor Distance to .4mm.
Another thing you can do is make the support weaker by decreasing the flow. You are at overall 95% flow so try dropping the Support Flow and Support Interface Flow to 87% or something. If it's too low it won't lay down correctly.
I've been running the Support Line Layer Thickness at 2X layer height so they only go down every other layer. In Cura 5.0 the high flow rate of doing that will cause a speed slow-down so you would need to adjust the Flow Equalization Ratio to 0%.
I've noticed that the top interface comes away from the print a lot better if it was cool when the initial skin went down on top of it. I haven't done it yet - but for small prints I'm considering adding a pause at height just to allow the interface to cool. Large prints was how I noticed the difference as the support always seems to come away easier.
A decent set of pics, a set of micro files, an Exacto hobby knife, a narrow sharpened screwdriver, and a pair of needle-nose pliers are necessary evils when dealing with support removal.
