I am impressed about the reusable desiccant for my #3dprinting filament.

You put it into the microwave oven at 600W for 5min and it is good to go again.

But there are some cave-ats:

• Don't do it in a porcelain container as it will get incredibly hot and take a long time to cool down.
• Don't get hasty because it takes so long to cool down. Don't put it too early in your 3D-printed container as it will melt through it.
• When it melts through, don't try to catch it with the (still incredibly hot) porcelain container which you grab with your bare hands.

So many valuable lessons this hobby has 😄.

Hmm, no love for either company, not sure how I'd like this one to go. :/

+1 for brims! Helps stick the part down, and very easy to pull off. Helpful to have a de-burring tool, but that's optional.

I don't like the amount of play (out-of-plane rotation) in the homemade bearing, but it'll be fine until it's not. It does feel like it'll still be able to turn under weight, which is what it needs to do. #robotics #3dPrinting

Creality introduces the K3, a next-gen multi-nozzle 3D printer

The K3 uses Creality’s KliTek system to physically swap nozzles in around 4.8 seconds, enabling faster multicolor and multi-material printing with virtually no purge waste. Different nozzle sizes can also be used for detail vs. speed.

Any of you #3dprinters out there have a Sovol Zero? I have one that is gathering dust because I can't get it to stick to the plate. I even picked up another plate and cut it down. Same issue.

Yes I am using dish soap and warm water to clean. I ran calibrations etc. glue stick, no glue stick. Fresh PLA.

Any one else rub into this issue or have other tweaks they would suggest?

They use #OpenStreetMap to create printable 3D models of an area, for people with no/bad vision to literally get a feel for the place.

Discoverable Terrain in TTRPGs

During the Covid-19 phase, my group went online. We used Roll20 to continue playing.

Some aspects of this transformation were bad, other aspects were good.

Among the things that worked better was the easy handling of discoverable terrain.

You (the GM) had the complete map, but revealed only what the players could see. One could easily have "hidden" points-of-interest that awaited their discovery on a second layer.

I have been looking into how I could preserve this discoverability when going onprem again.

For dungeons I was using "Dungeon Blocks" with self-printed blocks.

But for the maps of the region, I was still missing an option until I discovers Masters of the Realm.

This allows me to design a region at the PC and then create 3d-printed hex tiles to make it "physical".

As my printer (Bambulabs P2S) allows color changed per layer, I was able to reduce the "hand painting" of the tiles to a minimum.

Below you see images of the first map I used in an adventure today.

With a 3D printer you can print all the tools you need for #3dprinting 🤪

But it can't do something like a slingshot in 10 seconds and that's the speed that I want

@Timpostma @rl_dane

#3Dprinting #speed

What is the price range of such a 3D printer?

What is your opinion about the printing speed of 3D printers in general in comparison to a couple of years ago

One mean thing which prevents me from even looking at them is the fact that these things print extremely slow

Even basic shapes 3Dprint as slow as molasses

The progress in printing speed hasn't been as spectacular as I had envisioned

@rl_dane @Timpostma

Just remembered the Z-Hop* setting in #Cura. Now my C64 keyboard dust cover should hopefully print without incident. :D

* Causes the print head to jump up whenever moving over a printed layer to prevent the print head from snagging the part being printed and yanking it off the build surface (print/print head collision)

Apparently Creality are not great for Linux compatibility. Are there functional printer manufacturers and ranges that are better?

What kind of mask, preferably with changeable filters, should I wear when working with plastic? Cutting, heating and glueing it. And 3d printing.

New York & California now require 3D printers to "block" gun files.

Problem: a printer can't tell a gun part from a pipe fitting.

Open-source firmware can't be locked down either.

California AB 2047: The End of Open Source 3D Printing

California just introduced a bill that doesn't just regulate "ghost guns", it mandates a digital kill switch for every 3D printer sold. California AB 2047 requires "blocking technology" that connects your printer to a government-approved database before every single print. If the system goes down, or your file is flagged, your hardware becomes a paperweight.

This isn't just about firearms. This is the death of Open Source. If this bill passes, it effectively bans Marlin, Klipper, and Orca Slicer, forcing every manufacturer to lock down their firmware. It turns general-purpose computing into a walled garden where you only rent permission to use the hardware you own.
