I have a customer that wants me to engrave their logo onto a bunch of duplo bricks (legos, but larger). I would like to determine whether they might contain PVC but cannot find anything on their chemical composition. Does anyone know? Maybe someone has a kid with these and can look for information on the box? (my youngest is 20)

The material is ABS. Just checked with their tech support.

Sorry Mike, at least I never told everyone that you are actually Bob the Builder!

Is this a kind of a business card thing ?

That would be an intresting business card for a toymaker. Or like a Gymboree or MyGym.

I have no idea what they might do with them, it makes no sense to me. They are a high tech manufacturer of specialty hardware and software.

This is interesting. Are you going to put a fill in the engraved areas? Is it just the logo you are engraving? Please keep us posted on whatever info you can squeeze from them.

Maybe it is just a precursor to engraving on their engineers' robotics sets. Engineers are such children.

The best I could do was this (below) with settings 400 dpi, speed 90, power 70.

The plastic has a tendency to melt and leave a muddy look, much like extruded acrylic, but retains the original color so it's hard to read. For some reason blue and red come out better than green or yellow. The tagline on their logo is unreadable, it's about a 4 point font and I just can't get enough resolution with this material for it to show up clearly. It does look better than in the picture, but not what I'd consider satisfactory.

He'll be working on the artwork for another try.

I would experiment with two more things. One, try outlines instead of fills. Two, try something like 60 or 70 percent gray.

I tried something like this and tape helped with the clarity of the letters. Just blue painters tape.

Mike & Chris,

Both good suggestions that I'll try, but neither would help on that tiny text. I thing they are going to just leave it off.

The FiberMark would do a fantastic job on that stuff. ;)

It's not the best photo but a good example. To explain the FiberMark can get a dark mark on plastic. Less depth and more contrast. Oh.. and it can mark metal without cermark too! :D

I would love to get a FiberMark. But man them there things are pretty expensive. That would be a lot of DuploBlock marking !

You might want to make a deal with someone that has a fibermark.. I just logo etched a bunch of beveled glass plates for a fellow who's company just bought a fibermark machine.. Apparently they won't do glass..
If I had something that the fibermark would do better than the C02, I certainly would have made a deal with him..
