3D Printing

Using PrusaControl


Printer limitations:

  • Bed size
  • Bed should be heated for printing
  • Nozzle size – the smaller, the better, which results in better quality.
  • The bigger the nozzle, the higher the models will be printed.
  • Layer height – more layers, better quality but time consuming.
  • Printing temperature – different temperature should be set for each material.
  • Shell
  • Filling type
  • Orientation
  • Filament types
  • Finishing – sanding, resin coating, acetone bath, painting.

Adjusting the first layer:

  • The first layer of the model should be printed properly in order to print the entire model in a good condition. To properly stick the first layer onto the bed, use:
  • Hair spray
  • Glue stick
  • Painter tape

How to clean the bed:

  • Water
  • Alcohol
  • Acetone

Issues in 3D printer:

  • Warping

  • Solutions to avoid warping:

  • Raft
  • Brim
  • Skirt

Uses of 3D printing:

  • Prototypes
  • Medical field
  • Jewellery

Advantages of 3D printing:

  • Complex shapes
  • Easy to custom
  • Less material waste
  • More chances for creativity

Disadvantages of 3D printing:

  • Slow
  • Limited
  • Copy right issues
  • cannot print things which has copy rights.

When to 3D print:

  • Custom items whic are not available
  • Moulds for casting
  • Prototyping

When not to 3d print:

  • Creeping - when an object will be exposed to high temperature which will cause creeping.
  • When an object is exposed to high stress.
  • Mass production
  • Not always fastest solution
  • Contact with food

3D printing test:

  • I tested the printer to see its ability to print
  • I discovered that there are some areas and the accuracy is limited

3D design

  • I made a 3D design
  • I made a design on the Fusion 360 program in the third (third) week of the FAP Academy and made some adjustments to make it printable in the 3D printer
  • I adjusted the special neck of the robot to become a spiral neck
  • 3D design robot

  • Print ready design

Prusa I3 Mk2

Prusa is a 3-D printer that contains 3 axes (X-Y-Z). You can print all three-dimensional designs from converting the design to (G-Code). You can use more than one type of flement (ABS-PLA-TPU …)

  • I opened PrusaControl

  • I recalled the file from the desktop

  • I adjusted the settings and used a type of (TPU) to make some things more flexible

  • Printing started

  • After you finish printing

It took 4 hours and 7 minutes to print


Advantages and limitations of 3D printing


  • Capable of building more complex designs than traditional subtractive manufacturing techniques.
  • Ease of Access as its affordbale, small in size, and becomes available in most labs.
  • Minimize waste material as it prints only the required parts for the design with little support material.


  • Printing size is limited by the 3D printer size. Anything larger than the printing space need to be printed in seperate parts.
  • Printing materials types are few becuase not all plastics can be temperature controlled enough for 3D printing.
  • Printed parts with support need to be cleaned and smoothed to get the required finish.

How does the console work?

  • The developer company is the famous Microsoft company Consumption devices can be operated vertically. The front side is equipped with three cameras and a green LED. The central camera reads a color picture in space. Speed ​​- 30 frames per second. Continued analysis of the image under negative light background.

  • Scanned and prepared object (for 3D printing)

After I opened the program, I chose the settings

I summoned my friend Abdullah to be scanned

Then select the starting angle and it is the back

After finishing the survey I went to the settings and adjusted after the angles were not full

It was a successful experience and all the details are a little clear

You saved the file as (STL)

The final result

Download design files(ٍSTL)format

robot design


  • (because the program is in the free version when the file is converted to the required format, its quality decreases
