3D3D is a marine 3D printing and R&D company in New Brunswick, Canada. We make the parts you can't buy, manage projects you'd rather hand over, and build software and websites you own outright. One inbox, real machines, no pretending to be bigger than we are.
Where it came from
The founder, Randall Marshall, spent years working offshore sailboats, including time with Spartan Ocean Racing and Training. His first time ever on a sailboat was a February delivery from Lunenburg to Antigua that sailed into a bomb cyclone: four days of 75-knot wind, then nine more days to port. That story is here, and every pressure decision the company makes traces back to it.
The sailing years ended the way physical careers often do. After COVID he took an easier job, and then an ankylosing spondylitis diagnosis took that too. Just over a year ago, what remained got reassembled into a company: machines, judgment, and the habit of finishing things.
The RV chapter
The first month, 3D3D was an apartment with printers in it. Then it was a motorhome: printers on generator power through a hot New Brunswick summer, customer parts shipping on time anyway. Near the end of that summer came an invitation to crew the centenary Rolex Fastnet on an 80-foot maxi. The whole arc is here.
Now
A proper workspace, a Prusa Core One L on sponsorship from Prusa Research, a 12-app software shelf, two parametric products on the parts page, and a 1977 Farr 38 One Tonner named Mr Jumpa on the Saint John River, sponsored by High End Welding, where printed parts earn their place before they're offered to customers.
