Large Volume 3D Printer Build volume of 300x300x400mm Overall dimensions: X520-Y620-Z640 Built mainly with aluminum 20x20 and printed parts featuring an optimized, lightweight design. The extruder is a reliable MK8 model. Future designs will utilize a "Bowden" type for enhanced performance. The Y carriage with hot bed can be optimized further by cutting the aluminum sheet that holds the hot bed and replacing it with a 3mm glass panel. However, the current setup works effectively for my needs. The engine pap of the Y carriage has been upgraded from 1.7 A to 2 A to improve dynamics. All commercial elements, excluding aluminum profiles and chrome bars, have been sourced from Aliexpress. https://www.youtube.com/watch?v=Szj0oV3RGcY BOM: * 2 Screw and nut THSL-500-8Dx1 * Aluminum Profile 20x20 Type I Slot 5mm - 2x530; 3x360; 2x580 * 50 Nut Profile 5 tipo-I [M4] * 8 Linear Bearing LM8UU 8x15x24 * 4 Linear Bearing LM10UU 10x19x29 * 2 Chrome Bars 8mm - L445mm * 2 Chrome Bars 8mm - L530mm * 2 Chrome Bars 10mm - L530mm * 2 Coupling 5x8 * 1 Pulley GT2 6mm 20 Dientes eje 5mm * 1 Free Pulley GT2 6mm 20 Dientes eje 5mm * 1 M Belt GT2 6mm * 1 Pulley GT2 10mm 16 Dientes eje 5mm * 1 Free Pulley GT2 10mm 20 Dientes eje 5mm * 1 M Belt GT2 10mm * 1 GT2 Timing Belt Fixing 9x40mm * 1 steel shaft 5mm L18mm * 1 steel shaft 5mm L19.5mm * 1 Hot Bed Support Aluminium 324x324x3 * 1 Hot Bed 328x328x3 * 1 Hot Bed Glass 310x328x4 * 4 Rubber feet * 1 Extruder MK8 con Motor Nema 17 2A * 1 Motor Nema 17 2 A 59Ncm (eje Y) * 1 Motor Nema 17 1.7 A (eje X) * 2 Motor Nema 17 0.6 A (eje Z) * 4 Driver DRV8825 * 1 Ramps 1.4 Shield * 1 Arduino Mega * 1 RepRap LCD full graphic smart controller * 1 Power Supply 24V 20A * 1 Fan 80mm 12v * 1 Step Down Converter 24v to 12v / 9A 300W * 1 Fan 40mm 12v * 1 Relay Socket 12Volt 40A * 1 Switch 250 v 15 A * 3 Limit switches * Wires * 1 Cable Chain 10x20mm L0.5m * 1 Cable Chain 10x10mm L0.5m * M3 Screw Leveling Spring * Bolts M4 different lengths * Nuts M4 * Bolts M3 different lengths * Nuts M3 * PLA Filament 1 kg Edit 20-04-2018: The file Frame_Hot_Bed_mod.stl has been added, featuring the aluminum sheet that holds the hot bed.
