Introduction: Engraving Plastic With a Dremel

Right, you loan your whipper snipper to somebody, they use it and return their broken one claiming it was yours.

You feel disappointed that you have to buy a new one, you should do this to your whipper snipper so next time you loan it to someone they will know the difference between yours and theirs.

Lets start with a parts list:

  1. Dremel tool.
  2. 100 High Speed Cutter.

  3. whipper snipper.

  4. skill.

If I won the formlabs contest, I would begin making useful pieces with the 3D printer.

I have seen the printers before and I have a million ideas running through my head as to what I could make!

Teachers! Did you use this instructable in your classroom?

Step 1: Remove the Brand.

Sorry to Pope, I removed the label ;)

With your cutting tip on, grind away the label.

I thought that 25,000rpm was a good speed for removing the label.

Don't press too hard, in fact don't press at all! the weight of the tool is far more than enough to remove the label.

Only remove the brand an clean it up when you have finished.

Step 2: Engraving

Now that you don't have a brand on the machine, it is time to put your desired text on it.

Being a Pope machine I decided to put "POPS" on it.

To engrave plastic is a lot harder than metal, you have to go very slow and watch out for melting plastic, if you get melted plastic on your Dremel bit you can scrape it off with a file or similar.

I recommend using the dremel at a speed of 25,000rpm to engrave the text, when you have finished engraving you will notice that there will be a lot of burrs on the lettering, to remove this you will need to put the Dremel on 5,000rpm and run through the letters again focusing on the burred parts.

You can underline the text if you want.

Be careful that the chuck on the Dremel doesn't touch the plastic or it will start to engrave where you don't want it to, that is the only reason I put the underline where it is.

    Thanks for sharing. You could also fill the letters with black Sugru. This would make it look better, the surface would be smooth and the dirt would not collect there.

    a lot of plastics are ABS. so using a ABS slurry works well as a paint for ABS. the acetone will soften the part as its still has unevaporated acteone, but it will get hard again. once its hardened the slurry will basically join the part as if it was there from the start (not as a surface treatment like paint)
    a ABS slurry is ABS plastic dissolved in acetone. this is commonly used in 3d printing.

    when i use slurry, i use a stick and not a brush. depending on how much needs filling i go with a q-tip with the cotton removed, a 2mm swab with the tip removed, or a toothpick, (the 2mm swab is plastic not sure what type, but its not ABS so acetone will not soften it) the above makes for very sharp and percise lines

    if acetone scares you then model paint will work ok too. and i still recommend a toothpick and to paint with

    Yes, it would make a difference but I don't have Sugru!

    Cool idea! This would have been very helpful in my childhood house full of brothers... Thanks for sharing!
