Sally 4th has just added a 3D Print Bureau Service to the range of products that we offer to gamers and modellers. The service is really easy to use, just upload the files that you want printed, select the type of material you want used and the colour and add it to your basket. Turnaround is about a week to 10 days.
For printing miniatures you want to go with 'resin' as material.
A 28mm miniature will cost around £3-4 to have printed in resin.
