RidgeRunner Posted March 11, 2019 Share Posted March 11, 2019 I know this is a naive question but I am intrigued. How are such complex small parts designed for resin reproduction? I continue to be asstounded by the detail produced and woyld love to know how it is acheived. Thanks. Martin Link to comment Share on other sites More sharing options...
Schwarz-Brot Posted March 11, 2019 Share Posted March 11, 2019 Usually scratchbuilding, then bringing the master into a castable form by cutting into manageable pieces. Producing a form, casting. These days digital manufacuring comes more and more into play but is not able to reach the finest detail levels yet. This way the master would be modelled on a computer, 3d printed, formbuilding, casting. Link to comment Share on other sites More sharing options...

Schwarz-Brot Posted March 11, 2019 Share Posted March 11, 2019 I do not recognize any of these names (I'm a car guy, sorry), but yes, somehow a master has to be made, and that usually is scratchbuilt buy someone. There's other ways to get moulds for casting, but they are rare. For example the mould could be carved directly, like it was the case with very old plastic kits. AFAIK relief miniatures are done by carving the mould into slate. Link to comment Share on other sites More sharing options...
Sebastien Posted July 26, 2019 Share Posted July 26, 2019 (edited) A bit of post necromancy here, but there goes something that might interest you. This is how Vincent Kermorgant made his master for MDC 1/32 DB605. Hope you liked it. Cheers, S. Edited July 26, 2019 by Sebastien 11 1 Link to comment Share on other sites More sharing options...
RidgeRunner Posted July 26, 2019 Author Share Posted July 26, 2019 REally nice but really is how they produce smalll resin parts in, for example, 1/72, and in such volumes? Link to comment Share on other sites More sharing options...

Small resin part in 1/72 are made the same way : someone with golden fingers, quite a good pair of eyes, not necessarily too much time on their hands, and the urge to make something nice about a plane/train/tank/car/ship they really care about. Silicon molds can reproduce quite fine details. Their main problem is durability. But once you've got a master, you can do molds faster than you wear them out. Cheers, S.

Schwarz-Brot Posted July 26, 2019 Share Posted July 26, 2019 That's it. Every part is cast by hand. Like @Sebastien said - silikon is going to pick up even greasy fingerprints on the master - not kidding! And resin will happily replicate these.

I'm impressed and will treat these parts with more reverence in the future! Martin Link to comment Share on other sites More sharing options...

And the silicone and resin for making the parts aren't cheap. Especially when ruined by something you just didn't notice, or couldn't clearly see...

ElectroSoldier Posted November 6, 2019 Share Posted November 6, 2019 You take you original sculpt or part and either make a casting tool (mould) from it or cut it down into castable parts that you can make a mould from then cast the parts. The real cost of resin parts is paying for the original work. Making a sculpt or part can take me several weeks or even months. 1 Link to comment Share on other sites More sharing options...
