3D Laser Engraving | How To Make A Depth Map Out Of Almost Anything | STL to Depth Map | Tutorial 

If your viewer node does not have an export function try this out: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-UxvYij0EWWQ.html

BRO!!!!!! This is exactly what i've been trying to figure out how to do with my new CO2 laser

Blender 4.0 seems to have made this tutorial obsolete. The "depth" output from the Render node is missing now. They must have moved it, but I don't know where. I'm going to have to go back to a previous version. Not sure when it was removed.

I get similar results from my xtool d1 with about 40 minutes laser time, thats with the 10w head, so I was astounded to hear that. Love the info, gonna have to learn blender I guess

Eres el Mejor. Gracias.

Great tutorial and thank you for your assistance. I hope to see more Glowforge tutorials your explanations are definetly worth a sub! - Cheers

Awesome! Super cool video and breakdown. 👌 🆒️ 🙌

While my blender UI didn’t quite match this (latest version for Mac), it was good enough to get me through it. Thanks so much. I just used the default Glowforge’s 3D engrave setting

Cool! You could make 12 frames of animation and do a stop-motion engraved wood loop.

Thanks, I've been pulling my hair out figuring out "Bas-relief" for inverted engrave text. Now I just have to brainstorm Blender 😅

dude you're a legend

I don't have a connector for depth on my node in compositing. I have Image, Alpha, and Noisy Image. This may be due to a change with the blender 3.0 release. I'd uplload a screenshot but RU-vid isn't a fan of that :P Any ideas? Googled my butt off but I'm no blender pro.

Where do I save the image in version 2.93.4? There is no option under "ITEM / SAVE THE IMAGE". NODE, TOOL, VIEWER and OPTIONS only. How do I get the picture saved? Best regards

Try these using some solid basswood sheets instead of ply. They'd probably turn out far smoother in the end

Would like to see how the triceratops turned out too!

I have scrubbed wood with a toothbrush in alcohol as it does not affect wood, as water does. But I have not used it in the same 3d engraving as your doing. But the thinner the wood the more it can warp in water.

Great video looking to making a horse I had one with greyscale and it did not turn out great

Quick TIP... To clean up the wood after, use a cheap sand blaster with low PSI. It will sand the ash off the wood and you don't risk it warping from the water.... Your welcome!!

Brilliant

Great video, thanks

I don’t have a number pad what do I hit besides one?

When I jacked up the gamma for cutlines I put it at 9 million and there was still like one pixel of white showing, will that mess with process?

10:30 are you saying to make that it took 12 hours under a laser? or are you saying trail and error it took you 12 hours? I'm thinking of picking up a glowforge, but things like times is hard to come by.

Ty for the video, thts amazing! s2 ...so, you know if a diode neje 3 max can making this 3d depth effect, using this way tips? ty n advance

Good tutorial!

EZCAD2 or 3 just set input dxf or stl.. and bam.. or on any plotter kind (XY laser use Thunderlaser SW.. it support GRBL) or ise inkscape addon or correl addon.. or just simply download some from Vector Art Mega Collections.. it can do the same good job.. is nice video about makwing ez stuf.. extremly complicated for no reason..

Thanks man!

Would've been nice if you engraved the dinosaur image

Hi! Thanks for very useful and informative video! Which version of Blender was used in this video? I'm trying to save result of "Viewer" node, but I have no "Save This Image" option in "Item" tab.

I have been trying to do this and when I get to the click on viewer and save as PNG The Save as button does not show up in the item tab or any other that I could find. !!HELP!!

Great video, I have followed all the way through but there's no option to save the image for me :(

What about the detail in the image? The original stl had much more detail, it seems.

Would I be able to to 3D engraving on an OMtech laser machine since it has auto focus? Their models that have this start with AF and I am thinking of purchasing this one. AF2435-80

Hi Johnathan, I would like to ask how can I engraving ornament detail, copy it to other objects or files, and adjust it's length to match different size of objects? Basically re-use the same detail to multiple objects with different size. I'm trying to figure it out to make a set of keycaps. Thank you in advance. And thank you for those precision modeling videos with blender.

Excellent video and presentation, but it could have been more cohesive if you had shown the finished project.

I had the same "burned edges" issue with my laser cutter, and found out that an air eraser (an airbrush that sprays very fine particles) also cleaned the black off of laser cut wood.

i have no depth in the render layers node how can I fix that

You do something in this video that I find awesome but I won't tell you what it is so you don't overdo it. All I'm going to say is just continue being you!

I have made a Depth-map of a 3D object I haven't run it yet on my laser but how can I make a 2D image have depth because I know a picture is 2D but it has a 3D look.Can you help me?

Thanks for this video! Just what I was looking for. I have been wanting to perfect a way to making relief sculpture for awhile now. I tried scaling my subject so that it was more 2 dimensional before I rendered the depth map. I think the problem with things like that triceratops is that it's too dimensional, too deep. Your material is only so thick. I found a Blender developer who was working on an add-on for turning 3D into relief sculpture for a CNC router. It looked promising, but he wasn't finished with it.

I dont have depth in render lasers only noisy image

I don't have Save this image as in blender when on the viewer and hitting item

Following your tutorial but got lost in Compositing. I don't have depth in the Render Layers

Thanks a lot Excellent

Sir, could you do a video of 3D engraving to make a beautiful audio amplifier front panel?

obviously im doing something wrong buy my 'render layers' comes up with image, alpha, and noisy image instead of depth and i cant find on google how to change it

Great man. Is it possible to 20watts laser diode?

So, where is the triceratops engraving?

In this video, you see how to 3d printing with a laser 😂

It's a heightmap though

where the heck was the finished dinosaur that the entire video was about?

For all the fiddling with the software, the result looks like crap.

Brilliant
