Polyamide Bushing

Ball bearings are great because of precision and durability, but problematic because of noise during operation. Solution for this problem can be polimer bushing. Below you can see first home made Polyamide Bushings. They will be tested next weeks.

Hotbed

First hotbed we created from 5mm alloy plate, heated by 12 x 10W ceramic resistors. Resistors has been glued using fire resistant glue, it seems to be perfect. Bed is being used for nearly one year without any issues.

First hotbed prototype

New generation bed's are made from 4mm alloy, with working area 250 x 250mm. Power over 160W lets heat the bead in les than 10 minuts.

Hot bed is located on the solid base with thermal insulation in the middle.
