Design notes

The design rules are different than for laser cutting.

Read the design guide before you start your design.

Photochemical machining is great for intricate designs like jewelry and name badges. You can etch into one side of your design.

Can I get a sample?

You can get a sample here.

Typical uses

Jewelry, signage, furniture detail, mechanical parts.

Environmental info

Recyclable.

Adhesives, joints & fastenings

Brass is best connected with mechanical fastenings, soldering, or brazing.

A two part epoxy may be used to stick metal to other materials. For more info about gluing metal see this site.

Brass is pricey, but not THAT pricey! You guys are insane on your material markups......

Hi Brian -

If it seems like there is a markup, it may be because the cost of machining your designs is included in the material cost. Unlike the pricing for our other cutting services, PCM is a flat rate based on the size of your material. You can add as many designs as you like to maximize your material usage and lower the cost per unit. I hope that helps clear things up!

for miniature modeling purposes we would need much thinner materials and about 1/4 the cost for it to be functional is there any possibility of this to occur in the future?

Hi Harley. We have no current plans to add much thinner metal materials and our pricing is the best we can do for now. But we'd like to think there is still a possibility. We're always on the look out for new materials and ways to get our prices lower.

It all went well until I noticed your prices. Insane doesn't even begin to describe it.

Thanks Lev - Does this feel insane because you're thinking it's the cost of the material alone? To clarify, the pricing here is for the material AND unlimited cutting/etching. This means you can add unlimited designs to your metal sheet and the price does not change. (This is different from the pricing for our laser cutting services, where the material price is for the sheet only and you the cutting/etching cost all depends on the size of your design). Does this clarify?

Could this material be used for making cuff bracelets? Is the brass alloy flexible or would it break?

Hey Mark -

The brass alloy is pretty flexible, and can certainly be used to make bracelets. You can check out an example here:

I hope that helps for starters.

Any chance of a video of the manufacturing process? It would answer a lot of questions.
