Andy,

Listening to this weeks podcast I really would like to share with you a way to do high quality coloring inside prusaslicer.

If you look at my Printables Article: https://www.printables.com/article/kurt-as-non-obvious-to-him-at-least-prusa-slicer-s-YNYgb2d I updated section 5.2 with pictures for you.

In this article I color a circle in the center of a face of a cube. It's a simple process.

In the case of a more organic shape you can take the shape into a tool like tinkercad, cut it so that you have just the portion you wish to be a modifier for the base shape and then import that as a modifier.

How about California AB 2047? - requires 3D printers sold in the state to be DOJ‑approved and equipped with firearm‑blocking technology. It also criminalizes disabling or bypassing the blocking software. Maybe another bill, but it makes all open-source for 3D printers illegal.

California AB 2607? Requires firearm‑detection/blocking modules in all 3D printers sold in the state.

Colorado HB26‑1144? Bans manufacturing firearm components via 3D printing; bans digital instructions.

Washington HB 2321? - requires 3D printers to include blocking features that cannot be bypassed even by technically skilled users. Prohibits using 3D printers/CNC to manufacture certain firearm components; restricts digital firearm manufacturing code.

Just like in the firearm community, the problem is not the objects (firearms, bullets, 3d printed parts) it is politicians who are grossly uneducated, technophobic, and ignorant.

Andy - I was just listening to the "Impact Printing" - and you mentioned the video was uploaded to the forum here. But, I don't see it - at least - I don't see it within the podcast notes here - which is where I thought it would be. Will admit - this sounds VERY Intersting - so - I was really looking forward to seeing the video!!!

Wow - a VERY Interesting Video! Thanks Christof for sharing!!!

That being said...

It sure looks WEIRD! It's like a machine that is Pooping! Seriously - VERY similar to the Biological action of living beings. And, the exterior surface has a VERY Strange look to it!

Now - they did show Slicing of a printed wall - so, lower layers - and middle layers (middle between outer & inner walls) DID indeed show what looked to be inner viable solid and potential strength.

But, I gotta say - they look a long way from something truly acceptable - IMHO - as they exterior esthetics are Weird - and they really need to show Proof of full Walls being built - and a viable Home/Building - and not just a bunch of Test structures...
