A sneak peak in 3D printing

It takes years to build a single piece of scenery for 28mm miniatures, so a shift to a smaller scale was necessary. But some month are needed for a not so fancy 15mm terrain piece. The printed result of consumer Fused Filament printer was just horrible only a few ago and it wasn’t an option until I see the actual result in a shop, and I immediately bought one of those cheap chinese tool (publicity says ready to print).

Out of the box, the user manual says: Put the Y-Carriage into the Z-frame and just do this and do that. But the Z-frame was too tight for the Y-axis carriage. Disassemble the ready mounted part, un-tight and re-assemble.

Printer successfully mounted. But the carriage balance on the Z-frame. Add a few wooden feets. Test print. Hurra! Huuuu???? the print test is nearly successful but don’t stay on the bed. The bed had moved up. Re-level the bed and do some prints.

After a close inspection of the printer in action, a detail that can make cry a mechanic: the X-axis belt was touching the bearing block, producing a fine rubber dust = disassemble the printer and cut the block with a metal saw. Re-assemble the printer.

Always some misprints. Can not level the bed = try to tune the Y-rods. Again and again…….    ….and agaiiiiiiiin.  Disassemble the printer and put the rods on a marble: the Y-axis rods were bent. The powerful “Hand” tool made them straight less bent. Re-assemble the printer. A small noise. A ball on the table. A very small ball. A very small ball from the bearing ball. %&?!! (unspeakable word). The bearing is worn because of the bent rod. De-assemble the printer and put the other rods on the marble: they are all bent like bows, about one or two millimeter at each side. Some more unspeakable words. Tool “Hand” again and again. Re-assemble the printer. (If you buy one of those printer, the first thing to do BEFORE using it is verify the straightness of all the rods).

After a month full of hopes and delusions, a lot of misprints and a few beers, I eventually printed some useful things: a cap for a cutter, small accessories for the printer itself and…. a child’s dream…

a modular castle by Printable Scenery, reduced at 55% for 15-18mm miniatures.

Castle

It’s obviously only the beginning, as I intend to print a full walled city à la Carcassone.
