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.
Not sure what material you are using (different materials have different shrinkage characteristics), so some general things that helped me a lot getting dimensions right (all line widths that I use are the default widths, except for top/bottom which I 'upped' to .4mm:
- print outer wall before inner walls
- print infill before walls
- inset for outer wall .025mm
- get temperature of the nozzle right (too high will introduce minor discrepancies, when dimensions are critical, I use as low temperatures as I can to increase viscosity of the plastic when it's laid down on previous layer. But you have to be careful with lowering the temp since it can have a negative impact on layer bonding. So you will need to experiment with your type of filament to find that sweet spot.
One final thing: please realize that the printer is not printing a pure mathematical circle; instead it mimics a circle by using small lines connecting points on the circle. This also slightly reduces ID's. All things combined can indeed lead to a situation where you have to count these things in while doing the design (make ID's a little larger to obtain the ID you want).
Some more ideas that can help improve dimensional accuracy:
- use slower print speeds, especially the speeds on outer walls (don't ruin this by using high inner wall speeds though )
- lower print jerkEdited by Guest
