What type of DIY machine could do this?

[Pieter Swart]

Hi Guys, I am wondering,
I want to make some really flashy business cards for my wife... as a handy guy, I would rather try to build something and do it myself than to go find someone else to do it.
Check out this picture and let me know your thoughts.

Bare in mind, I am trying to it on a tiny if not non existent budget, using what I can find at either a Harbor freight, radio shack (If I can still find one) and maybe a few parts off of ebay.

Notice the honey comb cut out...This is what I am after... both stainless steel and aluminum

Google Chemical Etching Metal.

for the honeycomb..punch or powerful laser...neither will be cheap

For aluminum, a CNC machine could do this pretty easily --- esp. if you were willing to compromise on the tool paths and use a V-bit for detailing, and then a normal round bit for the through cut (it would leave a radius at the corners but with the V-engraved detailing it's not too bad).

Steel is tougher, CNC routers can sort of cut it, esp. w/ coolant, but it takes a lot of care with the toolpaths and feeds and speeds (Rich Cournoyer does this a lot, see his posts to various forums and, I think a YouTube channel) --- not getting these right can have a high cost in tooling. Also, due to low tool engagement one pretty much needs to be able to sharpen endmills so as to keep tooling costs reasonable, at least by my standards.

A "real" mill converted to CNC would do this quite handily, and a machine such as a Tormach would make short work of it.

One of my customers makes ribbon microphones with a stainless housing.
This one--

has 105 of those holes in it. He's been machining these holes with a mill, takes him 4 hours...He's been after me to help him figure out a way or a place to laser cut these. Since they have to be cut while still in cylinder form, most laser cutting shops can't do it, and the one (only one) he found wants $85 a pop and a 500 piece minimum. The $85 isn't so bad, but these are custom made, 500 would be a 30 year supply...

I could cut those holes out on that pic sample with several of my machines, in ALUMINUM, but it would take several minutes, depending the thick(thin)ness.

About all you could get from Harbor Freight that would help make a metal business card would be a shear to cut the blanks...

He did say DIY guys! Not the best video but a place to start your search.

Chemical milling , you could do it diy as the chemicals are cheap, a uv light box and etch resist all available, the professionals do these in big sheets, the etching does all the detail and the cutting, even the card shape

I have a follow up question. ( or two)

Based on what I have read above... Is it possible to cut this out with my 100w CO2 tube? material would be sublimation stock aluminum or slightly thicker. If you have done this, how thick was thickest stock used?


Below is my machine...

I'm not sure what sublimation stock aluminum is . Is it made for laser cutting. If its Aluminum I don't think you will cut or engrave it with a CO2 laser.

I Think Sublimation stock aluminum is measured in paper thickness, Its an aluminum label thin enough to be a bottle label or really thin (pathetic) business card...

At this point I think I might just order anodized blanks and engrave them or cermark a few cool Stainless steel cards for her... ( and myself while I'm at it...)

I also wtached that DIY Chemical etch video... Now That is cool!!!

Just a suggestion.

Try engraving business cards on clear cast acrylic. They look fantastic and you can make them from project scraps.
If you have to have aluminum a rotary engraver would be my first choice, you can do it on a CNC Router but its painfully slow.

Keith how thin can you find cast acrylic ? I made a friend some cards on veneer, they came out awesome.

Hey Bert!

I have seen something called Acrylic Precision Thin Sheet ranging from .2mm thick to 5mm thick. I have never used it though. Not sure what the properties or costs are. I think I saw it at Tap Plastics. I also use polycarb and petg sheets for some templates I make to help sketchers with perspective and proportions. Those hold up well in use, but I have never tried making something in the business card size to see how it would hold up in a wallet. I have also played with thinner sheets of mylar and acetate. Those cut well once you get the power and speed dialed in but were a bit thin for the sketching templates I mentioned.

I was just wondering on thickness as a card should be thin and flexable. I checked that out Dave but didn't see any prices or order info.

Blimey Kev, I have a 4 axis CO2 that would bang those out..shame your not in the UK, they would be closer to $8 a shot to do (if the tube was provided)
