Leaf Shape Metal Etching Bookmark 

 The metal etching process allows us to have strength and still have extremely fine detail on a variety of elements ,Examples of metal etching on our models are :people (at small scales) ,railings ,steps ,window ,frames ,screens ,antennas ,signs ,car parts  ,fences ,furniture ,etc ,Pieces can be etched on both sides of only one ,plus all the way through the metal .

Materials:

• Stainless Steel
• Steel Alloys
• Nickel
• Copper
• Copper Alloys
• Brass
• Beryllium Copper
• Kovar
• Invar
• Datum Alloy
• Steel Alloys
• Phosphorous Bronze

• The six steps of photochemical machining:

  1. Clean the metal in dilute acid solution to remove oils and contaminants
  2. Laminate photopolymer film on both sides
  3. Print the part patterns onto the coated metal and expose the photopolymer
  4. Develop the printed image to remove unexposed resist
  5. Etch the metal in ferric chloride solution
  6. Strip the resist in sodium hydroxide solution
