We are Cornwall's first commercial 3D printing hub, with the social goal of spreading the 3D Printing message round the Duchy. We have been printing since the summer of 2015 and now have clients ranging from corporate prototypers, through jewellers, students, hobbyists, arts centres, house restorers and a marionette designer. At the same time, we have been working with bodies like the Cornwall Chamber of Commerce and the Cornwall Marine Network to take this message into schools at the rate of around once every ten days during the last couple of academic years. We currently run four Ultimaker FDM printers, which lay filament down in layers. This year, we invested in a twin-nozzle Ultimaker 3 Extended, which means we can print designs of up to 30cm high, with complex interiors, and also in two colours. Since the  Autumn of 2017, we have been able to print in resin, which is more precise and tougher than FDM printing - but less flexible on a number of criteria. Thanks to financing from the Marine Challenge Fund - part of the ERDF’s European Structural and Investment Funds Growth Programme 2014-2020 - we have recently added a second resin printer to our armoury. We are steadily increasing the range of materials we can print with. We have one device under water in Falmouth Harbour, testing its performance in sea water. We have also printed in Nylon, Polycarbonite and a filament which is 20% carbon fibre.

In a test in autumn 2017, we found that one resin-printed device could withstand tension of 210 kg before breaking. An item printed in our basic thermoplastic could handle 160 kg. Over June 2018, we worked with Exeter Advanced Technologies Laboratory to investigate the effects of printing in a variety of different ways, thus deepening our understanding of the trade-off between printing time and the strength of the ultimate print. This was financed by Marine-i.


We can handle most prints of up to 20 cm cubed (though an object that large would take days to print). We can print at different speeds and to different degrees of precision. There's a vast range of colours you can call on and, if you require some particular kind of structural performance, we can advise on the filament which will best suit your needs.
