Missenden Abbey 3D Scanning Demonstration
In March I was invited to demonstrate 3D scanning at the Missenden Abbey Railway Modellers Spring weekend. Participants on the course were given forewarning to bring props and clothing of their choice, for creating miniature personalised figurines of themselves in 1930’s to 1950’s poses. A good number of people rose to the challenge, three people bringing boiler suits, firing shovels and grease tops (two of which were volunteer drivers on preservation lines), another bringing a pick axe. Props were used to simulate a fireman leaning out of a cab window and shepherd leaning on a gate!
The scanner is passed around the subject in 4 different height loops, starting with the torso, legs and feet, head and shoulders and lastly an angled scan from above the head. This process takes approximately 5 minutes, during which time the subject needs to maintain the required pose. Should some data not have been captured sufficiently the scanner can re-pass those areas. The scanned meshes are firstly edited to remove any unwanted material, or anomalies where the person being scanned may have moved slightly during the process. Once the meshes have been cleaned up and any holes closed they are ready to be printed. These prints are all at 30 microns XYZ, about 23mm high, equivalent to 5’9″ in OO Gauge.
For anyone thinking about going to a Missenden weekend I can highly recommend them, not just for the modelling and skills, but for the people you meet, the friends you make and the banter you have. It’s worked well for me saving a complex kit or a particular new skill for a Missenden weekend where so much help is on hand, not just from the experienced tutors but from other modellers as well. I’ve learnt much about tools, techniques and tips, all which should help further my modelling skills now I’m back home. What also makes the weekends so enjoyable is the time spent at dinner and in the bar, where you get to find out what others have been working on, maybe track building, weathering, lining, DCC, sounds etc or just having a chinwag and a laugh – so much is going on that the weekends fly by.
