0n30 Faur L45H - the first to be 3d printed
Times change... and so I turned to new technologies - 3D printing.
SLA Printers seem to be the right way to go in small scale modelling. Having different types on hand, drawings were made for test-prints. As the results have been pretty awesome, drawing continues....
3D Model of a L45H like loco in 1/4inch scale to run on 16.5mm track.
Drawn in DesignSpark Mechanical
Painted test-print (Form2).
The Formlabs Printers are awesome in resolution. Also it takes a lot of time for printing and post processing like curing and cutting of the supports. SLA UV LCD printers are much faster. Since I am not a "rivet counter" I can live with the lower resolution because I have other advantages such as almost no supports.
Since the print area on my Elegoo Mars is much smaller than on the Form2, I had to split the parts.
First unpainted sample, test run done - have to check the pickups....
First layers of colour...
3d printed prototype of powered bogie, worm gear and gear wheel modul 0.4- all printed!!
improved gearing and pickups - violin string wire as current collector
-waiting for sides to be printed to complete the bogie
first test run

exploded view: only wheel-sets, motor, couplers and screws are 3rd party...
lights still missing :-)
