Washing wood without warping

[alexbbrown]

My bottle of fingernail polish remover from “Studio 35 Beauty” says 100% Acetone on the label.

The 3d engraved wood (maple hardwood 1/8" PG) still warped after a dip in acetone.

I had a piece of non pg maple warp like a taco from alcohol. Amazing thing was that after about 4 or 5 days it’s neatly flat again. Not perfect, but not a debacle either.

This looks awesome!! I know its not the topic but i have a couple questions… What format to you use for this 3d Engrave… I’ve tried detailed vector art and rendering wouldn’t handle it! and do you use tape over the wood or just the material without the tapes protection? THANKS FOR SHARING!

[evansd2]

No masking. It was a raster piece pulled from wiki.

3D engraving takes a black-and-white bitmap image - you just need to rasterize your vector before you upload it.

[evansd2]

Not to correct @dan here (more like elaborate a bit), but 3d engraving needs a greyscale raster image (bitmap/png/jpeg) or an SVG or pdf with one embedded.

Black and white will not get depth gradients, you might as well be engraving rasters at that point.

I’d say black and white is a pretty accepted and generally understood term as far as images are concerned. I don’t think I’ve ever heard anyone say, “I love grayscale photography.” I’ve heard a lot of people say, “I love black and white photography.”

Here’s a good link to show what kind of images work well with 3D.

3D Greyscale file link 浮雕灰度图

Thought I’d share a nice find. I spent many an hours going down a rabbit hole in search of some images to practice 3D engraving with. I learned there are a LOT of images available on Chinese websites if you know what to search for. I can’t read any of the websites, so you are on your own as far as figuring our copyright, how to purchase the actual files etc. I downloaded a few to tweak and practice with for my own amusement and will not be using them commercially. If you google “how to spell (…

Here’s a bit more info about it

3D Engrave File types

This is actually perfect, because the Glowforge is currently not able to handle high resolution files of any meaningful size. It’s only been in development for more than two years… so far.

and some more examples here too

And then there was 3D

This is gonna be so much fun Did the crow without any adjustment to the file I had already made and still looks pretty darn cool. The last pic is just a sneak peek of something that turned out pretty neat if I do say so myself. (Not that I had much to do with it really.) After doing the initial 3D engraving with a photo of a CNC file made by Yura Tikhonovskiy, I’ve made some adjustment to the pic to see what further detail I can bring out. It’s cutting now. (I’m not going to pos…

@elyrada

do you use tape over the wood or just the material without the tapes protection?

I remove masking before engraving as it just turns gummy and can be hard to get off. I just clean the wood residue off with alcohol or orange cleaner. To me, the remaining discoloration adds depth and character to the engravings. YMMV of course .

…but we’re communicating with self-professed newbies who may or may not take it literally. In fact, oddly enough, I hear “black and white bitmap” and I literally think black and white pixel art. I hear “black and white jpeg” and I assume it’ll be greyscale. Clarity in instructions is never a bad thing.

Not to beat a dead horse, photography and it’s terms are sometimes completely different from computer graphics. Greyscale is definitely the correct and clear usage here. Black and white is very specific especially when followed by “bitmap.” If I didn’t know anything about 3D engraves, I’d have thought of a 1 bit image after reading that. So it was a fair clarification.
