Update yes, chines not yet, this is why.
Those leading edge pieces in the above post turned out to be underexposed, bugger. I worked it out trying to print small details on the 1/18th dash parts. These wouldn't resolve no matter how long I set the exposure time, the small high-res screen simply didn't have enough light power to cure the resin to the full extent.
So.... strip down the printer and dremel the steel body for the light box
Light box to project through the screen with 3 x 48 mini LED packs, lined with reflective aluminium tape. Made out of cardboard for a test, but proved to be ok so far, as in hasn't burnt the house down!
For the uneducated (LOL) screens work by opening pixels so the backlight can shine through.
Yes, blindin' mate. - colloquialism - see "Lock stock and two smoking barrels" for the non-british
Turns out you need this much as the screens are not really an open window to the light, was surprised to find the exposure time is only a little bit less than the standard tablet type screen.
So, did exposure testing with the 1/18th dash as printing it flat was fast.
Couple of little dimples from a bit of stuff in the tank, this was the 3rd or 4th test I think. But the tiny details resolved which would not form from the screen light alone.
1/18th dash with scale
1/48th dashes with scale
1/18th seat finished
Gant in seat
Under engine shrouds with small engine nozzles, broke 3 of 4, packed them too close together on the print bed.
Also had someone commission a full studio scale 1/12th beast, with detailed opening missile bays. Which has proved to be a challenge. Had to learn RC servos and tech. Was going to build a custom pcb, then discovered these.
Cheap car RC remote based on 2.4G tech, the stuff used in wireless keyboards and mice.
Still a work in progress, but strip out the stuff I need and get a box with 4 x AA battery compartment
Need to make holes for the ON/OFF switch and pot mount, and a suitable Firefox logo design
Mini servos to open the doors
Missile bays detailed, yet to be printed.
This is probably a bit confusing to look at for anyone but me.
Grey is FDM printed body part, yellow - resin printed missile bay, light blue - servo mount (will be merged with body print) Servo arm (white) turns and pushes door tab (orange).
The mechanical bit is all fingers crossed at the moment, but with brass tube hinges should work ok, and small neodymium magnets to keep the door shut.
Access to the battery compartment will be by removing the engine exhaust, can use 4 x AA batteries or rechargeable type.
Oh, and 1/12th body prints so far, actually not has big as I had in my head, had to break it up a bit differently as even with a 30cm x 30cm build size parts get near the limits.
Also building another custom FDM printer same as the one I have. Got a bargain two for one deal off the 'bay, sold one, so got what will be my second FDM printer for nearly free. Waiting on a few bits from China to finish it, also need to build a printer room to fit everything in!
