How to Engrave a Computer Window (Part 2)




This goes with How to engrave a Computer Window ( Part 1)This is optional but I think it looks cool.

Part 2 is taking that engraving and making it stand out. This makes the window look Tron like in a way. This is a nice effect but you do need some bright lights to make it look nice.

Step 1: Tools Needed.

Tools needed.

*The already engraved window or use use Part 1 make one

*Dremel - or other rotary tool that takes engraving bits.
*Flex-shaft - helps a lot to makes the tool feel lighter and *avoid mistakes.
*Engraving Bits - I used a 107. Any size will work. Smaller if *you want detail.
*Tape - now used to tape off what you don't want to paint
*Spray Paint - any color you want as long as it will stick to plexiglas. I used back.
*A good light.

Step 2: Tape Off What You Don't Want Painted.

Tape off what you don't want painted.

I had holes on my window for mounting that I did not want to get paint into.

Step 3: Spray Paint

Spray the side of the Plexiglas that is engraved. Use a spray paint that will stick to Plexiglas. Don't use latex paint

Step 4: Rengrave the Plexiglas

Now rengrave the Plexiglas going over what was already engraved. This is also time to add any detail to the window.

Step 5: Put It Back in Your Case.

Put it back in your case. Enjoy the glowing engraving.

My lights in the case are not bright enough to light the entire engraving. A blue CCFL bulb is behind the window.

if you are going to spray paint it black, why don't you just engrave straight through the case?

"cause then there'd be gaps in which dust can enter the computer case" is one reason I can think of for not going through the case itself. My goal for my custom made pc is to have it be airtight and still have optimal airflow

Or you could just take a plexiglass and thin masking tape and place it over the model,paint over then remove the masking tape.Much quicker and less messy.

A way you could get a similar effect but with a window that is still seethrough would be to purchase some UV reactive paint or ink and a UV light. Then simply paint the engraved parts with the UV reactive product and place the UV light inside.

I know when building plastic models you can cloud the clear plastic with acetone. Not sure if it'd work for plexiglass, but it might be worth a try. Just take the windows off, then apply acetone to the unpainted side. Be careful not too let it pool or to wipe too hard, as it may soften the surface and cause texturing. Best to try it on a corner first. Anyone else have an idea on this? Addemdum: You could sandblast the unpainted side to achieve the same effect, or go to town with fine grit sandpaper.

What do you mean? Usually the transformer has a plug that connects to a computers power supply molex plug.

That looks AWESOME! It would work with my Dell Dimension 2100, except it doesn't have blue LED lights in it. Maybe I can add them in. Awesome job, will there be any more parts? +1 rating. (added to favorites)

It might be because it is cast pleiglas. Extruded should frost when it is engraved.

nice! I like the contrast you get this way, looks great lol u totally get my +1 rating too :P

Great looking! I would rather spray it and then remove the paint, so the engraved parts are colored and the rest is clear

I made a few signs that way. For doing it to plexiglas i guess you could just paint your design into the cracks after engraving.
