Western Star Posted November 6, 2019 Share Posted November 6, 2019 I am building GWR 7mm coaches with interior gas lighting and using one LED per gas globe. I am using 3D prints FUD from Shapeways to provide the lamp base (between the globe and the underneath of the roof) and I am looking for a supplier who can offer 3D prints in clear/transparent/colourless resin for the "glass" part of the prototype. I have looked at offerings from Shapeways and (a) the "clear" resin that they offer is translucent/cloudy rather than clear whilst (b) the "optically-clear" offering is aimed at commercial/production quantities and hence prohibitive in price. Any suggestions as to which supplier can provide 3D prints in a resin which is going to look like a gas globe? At the moment my 3D CAD drawing for the globe is a solid, half, sphere so wall thickness is not an issue. thank you, Graham Link to post Share on other sites More sharing options...
RMweb Gold JCL Posted November 7, 2019 RMweb Gold Share Posted November 7, 2019 Hi Graham, I know that this isn't exactly what you're looking for, but are you set on 3D printing in clear resin, or have you thought about getting a prototype done and casting instead? Also, it might be worth talking to @Knuckles to see if he has looking into clear resin. 1 Link to post Share on other sites More sharing options...
Knuckles Posted November 7, 2019 Share Posted November 7, 2019 I've printed in clear resin before. Sometimes it does go a little cloudy so no guarantee there. Currently though I have no clear resin in stock, would have to spend around £20-50 to buy some. :-/ Usually use grey, black or white. Link to post Share on other sites More sharing options...

Almost all 3D prints have surface defects and will need to be polished to get an 'optically-clear' finish. 2 1 Link to post Share on other sites More sharing options...
RMweb Gold TheSignalEngineer Posted November 8, 2019 RMweb Gold Share Posted November 8, 2019 I've just had a sample for some glass vents which Guy Rixon is trying out for me on Shapways. They arrive milky white but when scrubbed up and polished/varnished they are fairly clear. Link to post Share on other sites More sharing options...

Are they instead glass covers for flat-flame burners? Link to post Share on other sites More sharing options...
