Bother, I seem to have bought another 3D printer...

I'm not sure how these things happen, but a DLP resin printer appears to have found its way into my possession!

£120 including 3 litres of assorted resin, a curing enclosure, 4 litres of IPA and a bunch of spares seemed like a very good deal!

Some test prints tomorrow and then time to print up some detailed parts for my next build. Can you tell what it is yet??

Brandy snap stuffed with extra thick cream?

Oh! Sorry..
That's my pudding. :)

Bench seats for a Trolley Bus?
Some kind of bridge?
Some kind of (horse drawn) wagon?

Well, you didn't expect serious answers, did you? :think:
 
India Pale Ale was designed to 'travel' better than other Ales.. :nerd:
 
I'm not sure about the IPA, it does look a little weak - almost like water some might say...
 
O dear..do print more
 
Not a trolleybus Phil - everybody would be in the driver's cab when he braked :) It looks like the inside of a tram to me!
 
Some the forum members have made fantastic models from Occre kits. I've always fancied having a go at one, but I feel my poor moddelling skills would not do justice to them. One day perhaps after lots of practice
 
They really are not that difficult to do. No special modelling skills required, just patience and the ability to do repetitive tasks like building seats and sanding and cutting wood to shape, that's all.

Trust me, if I can built one, anyone can!!

Now, back to the printer, it failed on it's first print, as the Z access froze. It may have been because it was in the summer house at not much above freezing and the mechanism just got too cold, so, I'm warming it up for another go! What it did print - first 20 layers or so looked all good, so no major issues.
 
It happens they multiply I have three now , One resin and two Filament, the resin likes to be in a warm environment when it prints which limits me as it's too cold out this time of year to use in the Garage and too Smelly to use in the house :)
 
I would have thought that the resin would be a little too viscous at such a low temperature?
 
The problem seems to lie with the Z axis. Whatever it's been lubricated with has turned to treacle at the low temps.

Printer has come inside to warm its cogs by the fire. The resin doesn't seem to change much in terms of viscosity, so I'm less worried about that.
 
2nd time lucky... A bit of warmth and the printer behaved itself. Once washed and hardened, these will be the outside frames for my London tram. They fit behind the false axle boxes and springs and will totally disappear once painted. 20201230_215249.jpg

Out of curiosity, why print them at an angle?
Click to expand...
Printing at an angle prevents warping of flat surfaces due to large volume changes in the amount of resin cured in one go. If you go from the support structure to a flat surface, the outside edges are likely to warp or not be printed correctly.
