the minimum thickness of a wall depends on your nozzle diameter (usually 0.4), so you can print walls with a minimum thickness of 0.4mm. (There are some options and tricks to print even thinner walls, but that's another story).
Or do you mean something else with your first question?
Regarding lampholder, no haven't done it personally, but why not? Depending on your lamp temperature you have to use the correct material, maybe something more heat resistant than normal PLA.
There are a lot of possibilities to import files into Fusion, but I think you mean not Fusion but Cura? In Cura you usually import STL files and these files can be scaled before printing.
You can always make a model solid if you select 100% infill, or if you make the walls thicker than the model itself. Except that solid is not perfectly solid: there will always be tiny gaps inbetween the extruded saugages. Printing slow minimises them, but does not eliminate them.
To make a wall print reliably, I always make all walls minimum 0.5mm wide in the CAD-design, for my 0.4mm fixed size nozzles (old UM2). When the file is exported to STL, smooth corners are cut into straight segments. So, in some spots a 0.40mm wall might become 0.41mm, and in others it might be 0.39mm, which in older slicer versions lead to that part not being printed because it was too thin (less than 0.4mm). So now I just stay on the safe side, and 0.5mm also works well on a design grid. (I don't know how newer slicer versions handle this, I haven't tried.)
Yes, I did make a lamp shade, but printed it in PET for better temperature resistance, and for translucency. There is a LED lamp inside now. Do not use PLA, even not for LED-lamps, CFL- or TL-lamps: they still go higher than 50°C. And even with PET (or any other higher temp material), allow air flow and some distance. All lamps are designed with some free airflow around them in mind. And even then, some of my LED spots still get to ca. 100°C (so I wonder how long they will live, definitely not the advertised 25000...50000 hours).
Never use 3D-printed parts for incandescent lamps: at best the plastic leaks away, at worst it could catch fire and burn down your whole house. These need heat resistant bakelite, porcelain, or similar.
🚀 Help Shape the Future of Cura and Digital Factory – Join Our Power User Research Program!
We’re looking for active users of Cura and Digital Factory — across professional and educational use cases — to help us improve the next generation of our tools.
Our Power User Research Program kicks off with a quick 15-minute interview to learn about your setup and workflows. If selected, you’ll be invited into a small group of users who get early access to features and help us shape the future of 3D printing software.
🧪 What to Expect:
A short 15-minute kickoff interview to help us get to know you If selected, bi-monthly research sessions (15–30 minutes) where we’ll test features, review workflows, or gather feedback Occasional invites to try out early prototypes or vote on upcoming improvements
🎁 What You’ll Get:
Selected participants receive a free 1-year Studio or Classroom license Early access to new features and tools A direct voice in what we build next
👉 Interested? Please fill out this quick form
Your feedback helps us make Cura Cloud more powerful, more intuitive, and more aligned with how you actually print and manage your workflow.
Thanks for being part of the community,
The full stable release of Cura 5.10 has arrived, and it brings support for the new Ultimaker S8, as well as new materials and profiles for previously supported UltiMaker printers. Additionally, you can now control your models in Cura using a 3D SpaceMouse and more!
