Cheap Diy 3d Printer Made of MDF
3d printing is really a awesome process because you can make anything you wants to make just design it and printer it but when it comes to a 3d printer it is a quite expensive in this instructables I will show you how to make a 3d printer So it's been a long time I wants to make a 3d printer I wants it to be cheap and compact and I went with cartesian type 3d printer I found it easy and simple to make and I don't have so many machines to build parts of it. So it is a completely hand made Diy 3d printer I try to make it a cheap as possible
Gather All the Components and Electronics
- I Choose MDF for frame construction because it is lighter and strong (6mm thick)
- 8mm standard ss rods 2x400mm,4x300mm
- 8mm linear bearing (LM8UU) 8pcs.
- 4 nema 17 stepper motor 1.7amp 4.2kg-cm
- Ramps 1.4 kit with Arduino mega
- Heatbed mk2
- Aluminum hotend v6
- Gt2 belt 2meter 6mm
- 2 ,20 tooth pulley
- Nema 14 flexible coupling
- Leadscrew 400mm
- Mostly parte I bought for eBay
- 2 100k thermistor
- Smps power supply of a PC should be about 450w
X Carriage
- First cut two pieces of 8x8 cm pick one and drill hole in middle A/Q first picture.
- Screw the stepper motor in it as shown in 2nd picture and tight the all 4 screws.
- Now mount all 3 LM8UU bearings with brackets which I made with aluminum sheet.
- Cut a U shape from one end to middle to make a way for gt2 pully A/Q to picture 6.
- I make a two keyways in each piece to support the rods with 2 washers and 4 nuts and bolts.
- These keyways should be parallal to each other and perpendicular to bearings in addition to avoid any mis aligment.
- Drill all the holes in both pieces to gather so that these pieces should screw well in a perfectly Alignment.
Y Carriage
- Cut a piece of MDF of same dimensions of bed with 2mm allowance to each side.
- Glue two pieces of margen parallal to each other to support the bearings .
- Mount 3 linear bearing as in picture and screw them with aluminum brackets and bolts.
- Than drill 4 holes at the corners and mount the bed with 4 springs to label the bed.
- Add a glass of 2mm on the bed of same size.
Z Carriage
- Cut two pieces of MDF of 42x9 cm A/Q to picture 1st .
- Than cut two square pieces of 9x9cm.
- Cut two pieces of margen and screw them together one by one with screws A/Q to picture 5.
- Drill two holes for the rods at a distance of 3.5 cm from one side on both pieces of 9x9 cm .
- Distance between these two rods varies according to the distance of x carriage bearings.
- Now screw another piece of 42x9 cm on another side and complete the tower.(picture 7).
Building the Base and Structure for Y Carriage
- Cut one piece of 30x34cm of same MDF for the base.
- Cut three stpips of MDF of 4.5x30 (1 piece ),4.5x33.5(2 pieces).
- Screw them with the help of screws.
- Next is to mount a stepper motor for Y axis according to picture 4&5.
- And add a bearing to support the gt2 belt as picture 6(I got this bearing from a old hard drive of a computer).
- Now mount the bed and tighten the belt .
- Next step is to screw the tower.
Assembling the Another Components
- Mount X carriage on tower by inserting the both rods on bearing.
- Than mount the stepper with leadscrew and nut .
- Mount the metal hotend with the help of two brackets .
- Mount the another bearing to the another side of X carriage to support the belt and I screw the belt on the carriage.
- Insert the hotend slide on X carriage.
- I mount linear bearing with the help of zip ties .
Mounting All the Electronics and Power Supply
- Insert all the jumpera on ramps 1.4 to select micro stepping.
- Insert all the a4988 stepper drivers on board with Arduino.
- Mount the power supply with double sided tape and secure the cable with zip ties .
- Now wire up all the components . It is open source so you found schematic and videos on internet .
- I mount ramps board on side of tower with zip ties
Testing and Trouble Shooting
- Adjust the height of bed .
- Calibrate the extruder and motors untill you get movement as per input .
- I printed many things and I have to say that the quality of print is quite good as compared to price of printer
- I printed these parts at the speed of 120mm /min and prints come out just fine .
- So this is all about my printer it took me about 2 weeks to completely build it up.
- So with this printer I will print the parts for my next hypercube .
- I am done here if you like the instructables please like and Vote.
- Thanks
