Научившись хорошо печатать можно и поэкспериментировать с настройками, например увеличить скорость печати.
По умолчанию скорость печати 80 mm/s я поставил 100 mm/s и увеличил температуру до 260 градусов.
Напечатал 2 фигурки с разными настройками заполнения и суппорта. Качество отличное!
// Axle/Hub for Lego wheel.
// Connects M3 motor shaft on Tajima motor/gearbox kit to Lego splined axle wheel.
//
// Printed at 0.2mm layers on UP!. Build 45degree overhangs with no support
//
// Motor shaft hole can be HEX, ROUND, or ROUND with FLAT
// Using metal hex threaded standoff for M3 connection
// standoff is M3x10mm x5mm across flats JAYCAR HP0900
// standoff is press fit into hex hole. Hole has domed ceiling so prints without support
//
// Lego axle design has keyholing to get cleaner inner corners than a simple cross, on the UP
// Has provision for two Flanges that can directly engage the inner surfaces of the wheel rim to provide support
// as the printed axle is prone to shearing under load.
// It is intended that the flange/s are interference fit into the hub parts,
// and that the wheel is forced all the way down the axle to the flange so the axle is not cantilevered
// Intended for insertion from the deep side of the wheel hub

Чернила для принтеров являются самой дорогой жидкостью.
Дороже нефти и золота, дороже чёрной икры.
А теперь посмотрите куда уходит большая часть чернил.
Принтер просто захлёбывается от отработанных чернил.
