The New 3D Printing Thread
Nice, they are getting that Scanner procedures down and close to making it for dummies. Only have to wait for the price to come down and offering everything that is in the video like the turntable, mat, calibration items and software. The couple I have seen are only the tripod and the scanner flatscreen thing. Thanks Nigels

or just harvest parts from a dead engine.  That's what I do.

It will come, it's coming along nicely and I reckon will be on the market in say 6 months or so in a final version. Smile

Possibly, but I don't see the point of sitting designing them unless there is a demand, I spent quite a bit of time on other projects that nobody seems interested in Smile

Update: I'm not sure how it will come out, but I've currently got my 'Daisy' model printing on the Mars, it seems it is able (just) to print a model that size.  Watch this space Big Grin

Wow, thats going to be a big print. Would the shell be printed upside down or right side up? Going to be interesting to see the details.

It gets printed upside down and at a 45 degree tilt, that minimises the flat surfaces on the vat surface (it's a techie issue Smile). It looks pretty good, just one issue that is down to the model which needs a little adjustment, but not sure how well it will photograph as I printed it in a translucent resin so its not so easy to see the detail, probably an undercoat will help Smile

Here we go, pictures of the print, not the best pictures and the model has literally just been printed, cleaned and cured, it still needs a bit of cleaning up and an undercoat.  The particular resin I was using, translucent blue, is not the best for showing the detail either, however you can see some detail that the FDM printers couldn't cope with such as the bits along the top of the windows.  You will also see the printing fault I mentioned on the third picture (3 diagonal lines) I think these are artifacts from a line that should run along the top of the side just below the edge of the roof, looking at my model it looks as thought it isn't quite as close to the model side as it should be and being loose has slipped and adhered to the side instead.  I'll have to tweak the model to fix that, but it shows promise Smile

Looking good Nigels

Question: Compared to the PLA 3D Prints, how much more flexible is the resin especially as it relates to the clip that holds the shell to the chassis?
[Image: super-smiley-emoticon.gif]
Reply
Now that is the million $ question Smile

As with all these things its not a simple answer, the 'normal' resins (consider them the equivalent of PLA filament) are rather brittle once cured.  However on the plus side they do tend to be stronger and don't suffer from the weakness of layer de-lamination which can happen with FDM prints.  Having said that at the sort of thickness this shell is printed the tabs should be quite strong but flexible enough to fit the shell etc.

Now it is possible to get more flexible resins, in fact the reason I bought this clear blue resin was that Elegoo's claims were that they had a new formulation which exhibits less smell (good thing) and more flexibility, they referred to it being more like ABS than PLA in the FDM world.  So I bought a bottle to try it, because I do find that very minute details such as antennae etc... on miniatures can be too brittle with standard resin.  Unfortunately I've found this resin to be just as bad if not even more brittle than the standard ones I'd used before.  I've had a long chat going with Elegoo on FB to try to establish if indeed I had the new formula or if it was old stock as it turns out the only way to tell is the production date on the bottle, but they insist it is the new formulation.  So it doesn't as far as I can see live up to the claims.

There are other resins that are specifically made to be more flexible, but they are more difficult to get hold of and are quite a bit more expensive, so for now I will be using the standard types until I either find a cheaper source or more formulations hit the market - it seems there are plenty in the pipeline.

Thanks Nigels

Now that I think of it, its not the Tabs that really need flexible but more the area's just above the tabs where the plastic would have to give inward just a little to release the Tabs from the chassis like at every battery change.

Exactly and with the size of the model there is I believe enough give in the shell to do that without it cracking or breaking.  If I can find a suitable chassis I'll try mounting it on one to be sure Smile
