I want to build some LED decorations for my room by illuminating

Not really no. Unless you're happy with it looking like shit of course.

>engraving by hand, without any tools whatsoever
yes if u have fingernails

>sharp
also yes

Well, I don't plan on making complex figures, so precision is not key here. That's why I would like to know whether it can be done with a screwdriver or so. Sounds stupid, but I don't know why it shouldn't work.

the patterns are usually just points on the acrylic that diffuse the light, so rough surfaces stand out, or deeper cuts or sharp changes in the angle of the surface are noticeable. so just scratching the surface works really well.

Alright, thank you! Might as well just try it since those sheets cost next to nothing.

Acrylic is laser engraved.

Also sorry for spamming (I would sage if I could) but how would you .. "isolate" the edges in the most efficient way?
I see that if I illuminate the sheet from the bottom with LED, light will also diffract from the sides and create annoying glares. Gluing something onto the sides would probably look horrendous. What do to prevent this?

Paint. White will reflect a bit more like internally (but only a bit, since most of it will be specular and diffuse out of the acrylic quickly), but be more visible. Black will be less visible but absorb essentially all light that hits it, meaning there's less available for the etchings.

Or you can polish the edges. This will allow the light to escape more-or-less parallel to the pane, eliminating glare except from very low angles.

There won't be a huge difference between the three in terms of how the etching itself looks.

aluminium tape might be able to stick to thin sides and you'll have to cut the exces

>>1065357

Sounds interesting. I will buy two sheets and test your tip with the extra one.

This would require really precise cutting which I probably can't do. The most narrow tapes here are 50mm and the acryl sheets are around 6mm. I might try it anyways.

Thanks for the answers!

nope, you just let it hang over the edge and slice off the excess using the plastic as a guide. a razor blade and a little practice will make it perfect.

In the end I followed your advice. Pic related is the final product. I am satisfied, although it has many things that could have been done better. Thanks for the advice!

Sucks ass by hand even with a dremel. Maybe trace with a file and hard pressure? Shouldnt need to be very deep. Not mine but pic related. Filling in by hand sucks. 1.5 trillion dots looks like cool scales. Have fun boyo.

I use automotive door edge trim guards like a boss. I have used black tape and shit like that and paint too. Anything that blocks light.

>>1065813
I made 50 of this with a dremel before i got the hang of it. Good job op

>>1065286
I gues u could. I used a dremel a lot. Needs hardly much of a scratch. Maybe a sharp knife or lay an imige down and trace with a hand file a few times?

By hand will suckass tho. I spent a lot of time with my old dremel and even it sucked. Thinner acriylic works just fine. Bonus points for cheap led strip and tape between 2 panels for multiple colors.

Have fun.
