Introduction: Building a 3D Printer Under 200$

Hello everyone

In this instructable I will show you how to make a 3d printer under 200$.

This 3D printer -Tower Simple XL, Maybe I should call it 3D printer of Sauron, lol.

This 3D printer have 6* 6* 6 Inches build volum and you can build it without any 3Dprint part.(*Laser cutting needed*)

If you like this instructable, comment and share this project with your friends who might like this instructable.

Thanks very much.

Step 1: Mechanical Parts List

I buy these things on Alibaba, these things will be more expensive on ebay.

This is the reason why I can build 3D printer under 200$.

M3 10mm screws *29

M3 16mm screws *48

M3 nuts *42

M4 16mm screws *4

M4 nuts *4

M4 shim *4

624 bearing *4

T8 Leadscrew 285mm *1

Leadscrew nuts *1

M3 spring 8mm *5

M5 spring 20mm *1

Coupler 5mm to 8mm *1

M3 pillars 16mm *5

M3 pillars 60mm *1

MXL 20T pulley *2

MXL belt *2

Cylinder Liner Rail Linear 8-215MM *4

Cylinder Liner Rail Linear 8-340MM *2

End stop *3

Nema 17 *4

Step 2: Lasercut Parts

Step 3: Laser Cut Wood

Laser cutting by 6 mm wood board

Step 4: Laser Cut Acrylic

Laser cutting by 6 mm acrylic

Step 5: Fixed Stepper Motors and 624 Bearings to Acrylic

Use m3 *10mm screws attach the nema 17 stepper motor to the acrylic piece

Step 6: Build the Main Body

Install acrylic part into main body

in this step we need to use the laser cut parts that i point out highlight

- Laser cut parts 1 &4 &5 &12 &16

Step 7: Mount the Leadscrew Nut

Mount the leadscrew nut into nut holder piece

in this step we need to use the laser cut part that i point out highlight

- Laser cut parts 8 &10

Step 8:

- First attach parts 9 and 11

- Then fit the two onto part 13

- Third attach previous assembly to the end of part 14

- Then add part 3 to the other end as depicted

- Fifth attach part 2 to the previously assembled parts

Step 9:

1:

- Zip tie bearings on to base plate as demonstrated

- Make sure to put the nub of the zip ties as shown

- Place smooth rods through the bearings to ensure alignment as zip ties are tightened

- Use pliers to tighten zip-ties as much as possible but be aware of the fragility of the wood

2:

- Zip-tie the bearings onto acrylic part as depicted

- Place smooth rods though bearings while zip-tying to ensure they are straight and parallel

- Tighten zip-ties using pliers

Step 10:

- Insert smooth rods into bearings

- Secure the previously assembled piece to smooth rods with a zip-tie on each end

- Make sure the zip-tie nobs are on the outer side of the assembly (otherwise they will obstruct y-axis movement)

Step 11:

- Insert smooth rods into LM8UU bearings

- Attach part 7 to rest of assembly by zip-tying it onto smooth rods- Make sure the nubs of the zip-ties are on the outer side of the print platform

- Make sure the M3 16mm screw is on the left side of the print platform

-Attach X axis MXL belt to wood part 7

Step 12:

-Attach the nema 17 stepper motor to wood part 4

-Attach Z axis endstop to wood part 4 with wood part 15

Step 13:

-Attach X axis endstop to wood part 4 on left side

-Attach M3*16 pillars to wood part 7

-Attach M3*16 screw with two M3 nuts to wood part 7

Step 14:

-Attach Y axis endstop to acrylic part on left side

-Insert the M3*16 screw through the wood part 8

-Then insert M3*60 pillar and M3 spring 8mm to the screw (to hit the Z endstop)

Step 15:

-Then insert M3*16 screw and M3 spring 8mm to the M3*16 pillars on wood part 6

And now we have successfully assembled a Tower Simple XL mechanical parts.

Next time i will publish the updated firmware and electronic parts assembly guide.

Step 16: Electronic Parts List

1. LCD 2004 *1

2. Arduino Mega 2560 *1

3. Ramps 1.4 *1

4. A4988 StepStick Stepper Motor Driver *4

5. 12V 40W Heating pipe *1

6. NTC Thermistor 100k

Step 17: Upload Firmware to Arduino Mega2560

1.Connecting Arduino Mega 2560 to computer.

2.Click install custom firmware.

3.Choose "TowerSimpleXL-2004" to upload (Ignore Warnings).

Step 18:

1. Attach A4988 StepStick Stepper Motor Driver to Ramps 1.4 motherboard.

2. Attach LCD 2004 to Ramps 1.4 motherboard.

3. Attach Ramps 1.4 motherboard to Arduino Mega 2560.

Step 19:

Connect the power, more than 6 amps of 12v power supply.

I also designed a control box to install the control panel.

Step 20: The Most Important Step

This is the most important step, I know you can't understand schematics, so, i hope you can understand the picture that i made.

Wiki of Ramps: http://www.reprap.org/wiki/Ramps

Step 21: Light It Up and Print Something

Finally completed.

Test, I print a xiaomi yi camera mount to replace the previous version and it works well. so meme.

Step 22: Place for Filament Roll

1. M4 shim *4

2. M4 16mm screws *4

3. M4 nuts *4

4. 624 bearing *4

5. Pipes 90mm diameter 13mm *2

This pipe can fit 624 bearing very well.

Step 23:

Attach M4 screws, M4 shims, 624 bearing and M4 nuts on mainbody.

It is convenient to roll filament.

3 Questions

By end stop do you men limit switches? if yes please tell the model number.

yes it is but i don't know the model number

hi almus yang , i really loved your instructables and i am going to make that 3D printer but i would like to know what is that blue thing in your bed ?

it is painters tape

Dear Mr/Mrs

I have to my thanks to you for your valuable work. Would u please tell me which stepper motor shall I use?
42HS02 or 42HS03?

did you use an extruder or what i really didn't understand but thx for all the efforts

1 reply

The extruder used was the MK8, but can be changed according to your choice

what changes do we need to do if we use gt2 pulley instead of mxl?

Hi!

I was wondering if you could e-mail me (orhn00@hotmail.com ) all the files for the project along with .hex firmware. Thanks for the instructable!

If you used marlin in the software, you should skip the configuration.h file (orhn00@hotmail.com)

Hi, I am currently making this printer. Any suggestion to what specs should I consider for my power supply? It would be a great help. Thank you.

I can use Marlin for firmware and Pronterface for this right? I'm kinda new to this.

Which application should we use to uploud the firm ware?

Hi
For teh level 17 we need to which program or which program you used and which version plz help me tnxx

How many extruders do we need in this printer?

Also, I can't seem to find the parts information for the extruder - is there a particular one you recommend? Thanks

1 reply

Most of people have used MK8 Extruder

I was wondering if this stepper motor can be used:

42 Stepper Motor 4 Leads 34mm 12V / 0.4A 26Ncm

Hi

Thanks for the great design :P

I cannot find the extruder part instructions. can anyone help me how to get to it?

Thanks

What sort of power supply is needed for this?

Yes in here we use 12 of those

Hello, I uploaded Marlin to arduino, but nothing shows on LCD, and Cura says the printer is not connected.
