I also have quite a few of Bill's prints and the resin he uses is superb - as you say it is very flexible. I'm confused. What are cast and what are printed? 1 Link to post Share on other sites More sharing options...

Assuming I've not misunderstood the question (very possible), casting uses a mould and the resin is poured, printing uses a 3D printer. 3 Link to post Share on other sites More sharing options...

This is the technique currently used by Mousa Models, I believe. 2 1 1 Link to post Share on other sites More sharing options...

Jol Wilkinson Posted July 2, 2023 Share Posted July 2, 2023 SLA resin printing can produce very good finishes, but is slow and messy. The finished product usually requires washing and UV curing. That is the system Bill Bedford (Mousa Models) and Modelu use (as do a lot of amateur 3d printers). High quality SLA 3D prints are sometimes used for master patterns for resin casting, as in the boiler/smokebox/chimney/dome/safety valve casting in the London Road Models LNWR 0-4-0T and 0-4-2T Crane Tank kits Filament printing uses a heated plastic filament extruded through a nozzle and generally doesn't produce such a smooth finish. I believe that is the system that Isinglass use. I think 3D printing is in a similar situation as early etched kits were, where the benefits and best application of the technology is still being understood. 5 Link to post Share on other sites More sharing options...

Yeah. 3D is definitely still a black art. Some of the stuff being produced is extremely good, some of it leaves a lot to be desired. All depends on the technical knowledge and experience of those doing it, their choice of materials and the quality of the equipment they can afford. And unless you're making shared models already developed by others, you have got to produce the data needed to drive the machine. I might have taken it up if the state of the art had become affordable a couple of decdes earlier, but I'm afraid there's too much of a learning curve for me, at my age I doubt I would be able to afford the time or the money needed to get to the standard I would want. But I definitely see business opportunities for those who can devote enough resources to it. 2 1 1 Link to post Share on other sites More sharing options...

Schooner Posted July 2, 2023 Share Posted July 2, 2023 (edited) Something which I think is probably also relevant is the ease and accessibility of design tools, and the very low investment required. As a little test, in between writing previous posts I was able to research, download, and learn via the in-program tutorials some new (to me) free CAD software, in this case Shapr3D. Within an hour's pottering about around other tasks, I had a passable (YMMV) clerestory roof design. The file could be sent to the printers in the morning, and I could have as many as I wanted in a day or two. Investment cost: £0. Even the time spent was 'dead' time when I'd only have been on RMWeb or whatever anyway. And it was kinda fun, and I had a quick look at some new software. I can outsource the production to a competitive commercial supplier - not cheap, but not ruinous. Preferable, in my circs at this time, to buying a printer and learning how to do it all myself. So I also have some control over my level of engagement, and associated set-up and production costs. Compare this to the time, effort, cost, and skill required to, IIUC, design a master build master create mould test mould buy resin trial cast correct master and mould production cast And really we still feel the need to ask why these little highly variable, low volume suck-it-and-see products are massively more popular as CAD and 3D printing projects...?! Personally, as I proved to myself not two days ago, I'd rather model bits and bobs by hand in the traditional media for things I need for myself because although the end result is 'worse' I enjoy the process more. It would still be disingenuous of me to pour scorn on any alternative methods. EDIT: I should probably make clear that whilst I have plans for a clerestory coach* I don't have any skin in the Genesis game, nor plans to join in the forseeable. *And the artwork, to be sent off to be etched once the backlog is reduced. Just as I'd anticipate using 3D printing services. Thanks to the sterling efforts of the likes of @BlueLightning and exciting plans of @Din and co, such services look set to improve dramatically for railway modellers, in additional to the continual growth in size and skill of 'domestic' producers.

Printing services at my shop at £3 per hour of print time (Plus postage), we don't charge cost for the resin as it is generally minimal anyway, I would imagine for a Genesis roof it would be 2 or 3 hours on the printer, so not massive costs. Not an advert, just trying to add to the costs of printing argument. and detail can be quite impressive, this axlebox is 4mm, the layer lies are invisible with the naked eye. this is a failed test print, so ignore the wobbliness of the solebar above, and the extra material on the bottom of the springs Gary Edited July 3, 2023 by BlueLightning 9 5 2 1 Link to post Share on other sites More sharing options...

But that is true of pretty well all types of modelling. One has to practice and to accept that you will have failures, or at least less than ideal results, along the way. 1 4 Link to post Share on other sites More sharing options...

I would agree with Compound that the same can be said for most aspects of modelling, in this case, I knew it would fail before I printed it, I wanted to try some settings on the printer I wouldn't usually touch, and had a file that would show the results well enough even though it wasn't suitably prepared. The results of the test were that I won't be touching those settings again, the improvement I got from them was not enough to justify the extra time spent printing. So that was very much a case of learning the machine more, and improving my own skill set with the software associated with it. Gary EDIT: I should add that under the proper settings that I set the file up for I have printed many many copies of it just fine, and learning how to setup the prints didn't take long, 99% of my files don't need tweaking after initial setup.

barrymx5 Posted July 19, 2023 Share Posted July 19, 2023 Hattons really have missed a trick with SDJR coaches. Slated for batch 3 with no projected date. Those who grew impatient and finally decided to buy the probably inferior Hornby version which was recently released are finding they are like hens teeth. 5 3 Link to post Share on other sites More sharing options...

NZRedBaron Posted August 1, 2023 Share Posted August 1, 2023 (edited) Got to say, the L&YR coaches look right smashing, they do; kind of makes me wonder/hope if Bachmann could be persuaded into doing another run of the Aspinall Class 5's in LYR colours.

The formation guides were pretty much fantasy. So long as you've got a brake end or full brake at each end and the first class in the middle, you won't go far wrong. 8 2 1 Link to post Share on other sites More sharing options...
