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.
First of all don't do 100% infill. It wastes time and filament and doesn't increase strength. Well it doesn't affect bending strength or pulling strength but it does help crushing strength (if you stand on the print - infill will help).
wall-not-adhering is always an underextrusion issue. Because you had the problem the most with 100% infill then I'm guessing your infill printing speed is higher than your wall speed and the infill speed is too high where it's underextruding.
But there are easily 20 possible causes for underextrusion. they are all "fixed" by slowing down. a lot. Try 4X or 8X slower. Just to see what happens. You should be able to adjust print speed on the fly. But even if that fixes it you may have a desire to print faster and there may be something you can do about that. I don't know.
Yes you should absolutely get a cooling fan. Quality will increase. Particularly for overhangs. You want to cool the part without cooling the nozzle if possible. If you use a fan you have to worry about back pressure - most fan shrouds block flow too much and the fan is useless. Blowers don't mind back pressure.

Thank you for your advice. Will try to slow it down. It seems some areas of the part can deal with the speed. I have to figure out how to slice certain parts faster. I have zero issues with overhangs without a fan so far. But will probably use one.
