3D Printer

Until now I’d not taken the leap into the world of 3D printing. I’d followed the various designs as they improved but always thought that the outputs from the lower cost printers did not look professional enough.

Derby Silk Mill – Maker in Residence

From November 2014 until May 2015, I have been one of four “Makers in Residence” at Derby Silk Mill, in the UK.
