3D Scanning and Printing

Group  Assignment

Test the design rules for your 3D printer(s)


What is 3D Printing

3D Printing is an Additive Manufacturing technology that creates 3d objects by building layer by layer.

Fullspectrum Laser Cutter

At our TalentS Lab there are 4 different 3D printers available:


  1. Prusa i3 MK3
  3. Ultimaker 2 Extended +
  5. Anycubic photo DLP
  7. Creality CR-10

In this group assignment, we had to test our printer by printing a standard model to test the design rules for your 3D printer. We printed the test model using the Prusa i3 MK3 printer.

Prusa i3 MK3S

laser adjustment
  • Build volume : 25 x 21 x 21 cm

  • Layer height : 0.05 – 0.35 mm

  • Max travel speed: 200+ mm/s

  • Max hotend/heatbed temp. : 300 °C / 120 °C (572 °F / 248 °F)

  • Supports only a 1.75 mm filament.

What is Filament ?

3D printing filament is a type of plastic called thermoplastics that becomes flexible when it is exposed to heat with the right temperature. This material allows the printer to create different shapes by forming the filament before it cools down.  


There are many types of filaments to 3d printer can use:


1- ABS Filament

2- PLA Filament

3- PET Filament

4- PETT Filament

5- Nylon Filament

6- PVA Filament

7- Sandstone Filament

8- Wood Filament

9- Metal Filament

10- HIPS Filament

11- Magnetic Iron Filament

12- Conductive Filament

13- Carbon Fiber Filament

14- TPE Filament

15- Glow in the Dark Filament

16- Amphora Filament

A-Test the design rules for your printer(s)

  • OK, We have 3 types of 3D printers in the lab, CR-10, Ultimaker 2+extended and Prusa MK3s.

  • the one that I am using almost all the time is Prusa, for all the specs and extra futurs that are available in it. I also have Alfawise u20 in my home, just as hoppy printing and so on.....
    Now let's go with prusa MK3s specs :building space (25 x 21 x 21 cm)

  • filament size (1.75mm)

  • Layer height start from 0.05mm

  • support for a lot of materials PLA, ABS, PET, HIPS, Flex PP... etc. , we usually use PLA..... the nozzle and bed can also support all these materials with a variety of temperatures

  • Heated bed

  • what else.... there are alto to like in this printer, and for more info please check this link: Prusa MK3

  • most of use are using Prusa for printing, so all the team agreed to work and test prusa sitting, and what else to search on for STL file that the grate Thingiverse (All In One 3D Printer test)


    This design will tes the following:support test:

  • scale test

  • overhang test

  • hole test

  • diameter test

  • bridging test

We are using PLA filament and 0.4mm nozzle:
how to use the slicing software Prusa Slicer
first what are slicer softwares? They are a converstors from 3D objects that we design in 3D design softwares like onshape and others to a layer that the 3D printer can understand and work on..

Laser seetings

We are using this sitting for printing with .2mm lighter height (can be described as the resolution of the print), then the filament we are suing (PLA), printer type, if there is any need to add support or not and finally, how much material we need inside the print (20% of the print is filled) :

Laser seetings

with the previous sitting, the slicer is giving the following needed time, materials info for the print:

Laser seetings

It will take 4h and ~40m and it will use ~50gr of filament Save "Export G-code" and go to the printer


Please check the video about 3D printing the test object:


Printing, layer by layer....

Laser seetings

after printing, we saw some problems with the finishing...

Laser seetings

As you can see, there are some thin lines between the parts flying,Scaling was not perfect as well. with error of 6% for X with fast printing sittings and 0.2mm layer height almost all other things were good
