Expired US Patent 5,280,051 describes how to make Artificial Marble or Granite.
See attached, or [url removed, login to view]
My plan is to produce large 3D printed objects, like the company "D-Shape" do: [url removed, login to view] - this patent might even describe the actual binder they are using.
Your task will be to understand the patent, to consult with me over the best choice for me to use for my "mineral filler" (in particular, can beach sand be used?), to learn about my proposed printing machine, and then decide which is the best liquid binder formulation to use for my purposes.
You will also need to either produce some test quantities for me, and ship it to my address in Australia, or to provide to me the instructions for me (a layman) to follow to prepare the binder, along with a list of suppliers and instructions for me to follow to order the ingredients.
The patent mentions washing, so if this will be needed, additional instructions like the above will be needed to produce the washing agent. The patent also mentions other potential additives. Again, if these are determined to be needed (e.g. colors and fire-retardants and UV stabilizers and decorative additives), help with sourcing will be needed.
When bidding, please give me sufficient information about you and/or your skills/education/experience/resources so I can attempt to determine if you're going to be able to complete this project!
Please also bid a sensible amount (I'm just one guy on a budget here), and please EXCLUDE the cost of ingredients, expenses, and shipping, but please do MENTION any expenses that you know in advance you might have (eg: lab/equipment hire-time etc). My plan is to buy the ingredients etc as necessary, and ship them to you at my expense, and to also pay for any other shipping etc myself.
