Yes I did a Search. Seems ABS is too short and it does not work. Anyway does cutting or engraving ABS cause bad things to happen to your machine or you?

Cuts and engraves like play-doh :( the hazards are there but not as bad as pvc (I still won't cut it without normal PVC scrubbers in use though)

It cuts and engraves, but it's quite melty. The edge tends to roll up a big burr and the cut edge has a weird finish on it, not smooth like acrylic. It cuts though. It's not something I do a lot of but from time to time, a few customers have jobs they bring in with it.

Same here, 1/16" and less is fine with water-misted transfer tape on it, the thicker it gets the uglier. Engraving requires 2+ passes but looks good if you use a textured surface ABS such as pebble or leather.

I was thinking a 3D printed something and it could have a light engraving, no cutting. Thanks for the input.

That'll work, just go easy on it and it'll be fine.

I won't even bother lasering ABS, all the laser does is 'push' the material around. ABS doesn't tool engrave all that great either.

My main use for the stuff is sacrificial, it goes under the aluminum sheets I machine into operator panels.

Before i learned about the health hazards is used to cut abs often. It always cut well for me. And i could engrave it with pretty decent succes. None high detail stuff like text or simple logos

Bill, the abs wire used in extruder 3d printers is often quite different to normal abs sheet.

I did some samples today and it looked fine, might need a little more power next time around but it works.

Dave,

You are playing with 3D printing now aren't you? How far have you taken it? Just curious.

I've had a Z-corp Z650 for some time now and a couple of CEL robox models recently but to be honest it's all rather slow for anything near production work. The Z-Corp is expensive to run in consumables and the CEL models aren't particularly accurate.

It will come with time ;)

Bill,

Rowmark rotary engravable stock is ABS (as per their spects).
It does laser cut but not as good as laser stock sheets. Some colors can be laser engraved with good results as well.

This is the ABS I'm talking about-- While Rowmark might be ABS, it's nothing like THIS stuff, which is basic 1/16" thick black ABS sheet, dull smooth back, mottled front.

Did some test engravings with my 40w LS900--as it says: 50 power 100 speed, 100 both, and 100 power 50 speed. 500 LPI, 800 DPI...

On the mottled side you can barely tell anything happened

Shows up on the back side, it does "mark" okay, but not what I'd call 'high quality'...

Close up, shows how the stuff mostly just melts. And it smells like burnt cat pi**, it's horrible!

Dave, Another silly question for you. Where does your quote come from in your signature? I feel like I should know it but can't find a reference to it anywhere? Just curious....like always! <grin>

Kids TV show of the late 60's early 70's called "Mr Ben" :)

Thanks Dave! So it was a British Show! That explains why I couldn't find a reference to it here. Sounds like a fun premise for a kids show! Now if I can just figure out why it seemed like I should know the phrase? <grin>
