Startup costs are typically around $3,000 to $15,000, depending on whether you buy a 3D printer, silicones and resins, ventilation and protective gear, or machined aluminium tooling. These are estimates, so price your own equipment list before you commit.

Monthly revenue is typically around $1,000 to $5,000, depending on how many customers you win, the size of each job and your hours. These are estimates of revenue before costs. Expect to spend at least about 10 hours a week.

Check fumes and chemical handling, including safety data sheets, ventilation and protective gear. Check council approval for a home-based business and any limits on noise, deliveries or chemicals. Also check public liability and product liability insurance, customer rights to designs, and GST registration.
