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.
Often it's because the acceleration / jerk is not setup correctly in Cura. It's an issue that people run into more often. See https://3dprinting.stackexchange.com/questions/4066/estimating-printing-time-from-cura
We don't make the profiles for third party printers (they are contributed to us by community members) so we can't guarantee that the numbers they contain are actually correct.

This is not the same as seeing the "correct" time in the Cura window, but maybe it's something you can use.
I made a request for a plugin about a year ago and one of the contributors to Cura adapted an existing one and came up with "ShowProgress.py" that I'll attach as a zip file. I like it because it has a "speed factor" in it for the print time. If Cura tells you a print will take 1 hr and you know from experience that it will take 1.25 hours then the fudge factor would be 1/1.25 = 0.8.
If your firmware supports M117 then "1/240 | ET 4H03M" will appear on the LCD at layer changes. The Cura "TIME:" line is not affected and will always show the print time that Cura calculated in total seconds.
(I run Windows so adjust accordingly for Linux or Mac) Unzip the file and copy it to:
"...\Ultimaker Cura 4.x.x\plugins\PostProcessingPlugin\scripts. It will show up as a Post Processing Script the next time you start Cura. I found that for my printer a Fudge Factor of 1.1 works well. I don't see it when I slice, but it shows up on the LCD during a print and counts down to the finish while the layers count up.
