Introduction: How to Etch Copper (+DIY Etchant, Alternative to Ferric Chloride)

In this tutorial, you will learn one technique to etch your own designs into copper. These designs can be printed from your laser printer onto Press-N-Peel paper, OR you can simply draw them onto the copper with a marker. I will also show you the Muriatic Acid and Hydrogen Peroxide etchant mixture I use as an alternative to Ferric Chloride.

Step 1: How to Etch Copper (+ DIY Etchant Mixture)

You will need the following tools and materials:

  • Copper sheet
  • Heat gun
  • Press-n-Peel Blue (Search eBay for "Press-n-Peel Blue")
  • ** OR, if you'd rather draw the design by hand, just us a black Sharpie marker.
  • Etchant (You can use Ferric Chloride, but I also show how to mix Muriatic Acid and Hydrogen Peroxide)
  • Acetone OR Fine Sand paper (400 grit or higher)
  • Plastic Cups
  • Paper Towels
