My DIY 3D printer
Recently I have assembled and build my first 3D printer. I have built this following 3D printer using the Tevo’s Tarantula DIY kit.
This kit consists following main parts: LCD Display controller (to control main board & printing) 3 END stop switch (for X,Y,Z coordinate stop location settings 4 Nema 17 stepper motors Aluminum Extruder with cooling fan for 1.75mm Filament Titan and normal extruder Motherboard RepRap Ramps1.4 30mm Fan for hot-end heat nozzle 40mm Fan for PCB – motherboard cooling GT2 belt for x & y axis Coupler and Lead screw rod for z axis Heat nozzle PTFE tube PTFE fitting hot ends PTFE fitting extruder Heat block wires and other connecting wires Heat bed (200 x 200) ABS & PLA filaments 220V to 12V converters Aluminum frames, fasteners, nuts & bolts etc. After assembly you have to perform following steps before final 3D print (mechanical and electrical assembly instructions are available in YouTube)
Check movements of all stepper motors Move nozzle to x,y & z co-ordinate freely Remove all noises and make sure free movement of nozzle heads Pre-heat bed at 70 degree and nozzle up to 210 degree Celsius Perform bed leveling (keep a gap between nozzle and bed closed to 1mm in all the points) Load filament and test extrusion by moving extruder motor using LCD panel Create 3D objects in AutoCAD or in TinkerCAD (any CAD software) Load 3D drawing (STL files) in Repetier Host (this is a slicer tool , which converts STL files to G-Code) Setup Repetier Host for printer (important setting printer shape, bed size, filament size, speed etc) Convert STL flies to Gcode using slicer and save the file into SD card Load the SD card into the LCD panel And start printing from SD card
Cost of all parts are approx. 200$. And total weight is 8KG. It has taken 3-4 days for me to complete the assembly and to print a sample object perfectly.
