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.
Have you replaced the bowden tube recently? You can experience wear and tear with it over time, or have debris like ground up filament work it's way into it, causing the filament not to move smoothly.
The first place to look at if all the hardware is good would be your settings in Cura to determine your volumetric extrusion rate. You calculate this by using your nozzle width X layer height X print speed to get your extrusion rate in mm^3/second.
8mm^3/s running PLA at 230 C is considered a pretty healthy extrusion rate for this test. You can download the gcode here, which will automatically set the temperature 230 for this print: https://www.youmagine.com/designs/test-print-for-ultimaker--2
This should give a baseline for how much under extrusion you're seeing, or whether the issue may be related to the gcode.
If you're towards the end of a filament reel and it's very tightly wound, you might also start to see some under extrusion because the printer is having to work harder to unwind it and get it through the bowden tube.
You mentioned replacing parts of the hot end--is your fan shroud touching the nozzle? If it is, it will act as a heat sink, and can cause under extrusion.
