doug72 Posted January 18, 2016 Posted January 18, 2016 Most 3D printed parts are white with coloured alternatives costing more. As an experiment I sourced a grey paint marker pen on line. Arrived today and tested on white lego parts and on white 3D printed parts. The marker pen works well, is resonably quick drying with a matt finish. Pen used :- Posca grey 8mm Bold Marker Pen, i.d. 148924000 £3.99 each with free postage. Obtained from: easichalk.com Colour is a very close match to Lego Light Grey. Pen I brought has a 8mm chisel point which OK for large surface areas but a smaller 2mm pen would be better for finer details, recesses etc. Quote

As requested: LEGO Rim Narrow Ø 18 x 7 M Cross (56903 Left, unpainted part left, Right after painting. Marker paint pen used. IMG_3013 by Doug Ridgway, on Flickr View of Efferman two 3 x 3 x 3 worm gearboxes installed in my R & R mobile crane. note; these were painted in situ. IMG_3014 by Doug Ridgway, on Flickr View of 3 x 3 x 3 worm gearbox installed in Dockside crane, Painted using a black marker pen prior to installing IMG_3016 by Doug Ridgway, on Flickr Ideally parts should be painted prior to installing and only on visible sections and not subject to wear. ie. Turntable support - don't paint running surface where wheel holder wheels ride or the tooth ring. Note marker pen used has 8mm tip, for finer detailing a 2.5mm tip would be better. The paint appears to adhere well to the slightly grainy surface of the 3D printed parts. Edited January 18, 2016 by Doug72 Quote
efferman Posted January 18, 2016 Posted January 18, 2016 thank you very much. It seems the grey marker fits really well. Quote
