Prototype and Short-Run Mould Maker

Product designers, startups, makers with consumer products, small manufacturers and workshops that need a few dozen to a few thousand parts.

Fixed price per mould design and build, often with extra charges for revisions, test casts or producing the first batch of parts.

• CAD modelling
• 3D printing and casting techniques
• Understanding materials such as silicone, resin and urethane
• Clear communication with non-technical clients

• Ventilation, safe handling and storage of resins, silicones and solvents (check workplace safety guidance in your province)
• Home-based business rules, zoning, noise and any fire or insurance restrictions on a home workshop (check with your municipality and insurer)
• Commercial general liability insurance, and clarity on who is responsible if a mould or cast part fails in use
• Protecting clients' designs with simple confidentiality agreements and being careful not to copy someone else's protected product
• Moulds made with softer materials wear out quickly, so be honest with clients about how many parts they can expect

Startup costs are typically estimated at around $5,000 to $30,000, depending on the 3D printers, casting supplies and desktop machining equipment you buy. Working from home can keep premises costs down.

Monthly revenue is typically estimated at around $2,000 to $10,000, depending on your equipment, your clients and the size of their runs. Many people start at about 15 hours a week.

Check ventilation and safe handling of resins, silicones and solvents with your provincial workplace safety guidance, plus home-based business rules, zoning and insurer restrictions. Also check liability insurance and use confidentiality agreements with clients.
