Makerspace: 3D Printing

Provide a collaborative technologically focused environment for SU students and staff to invent, create and learn while sharing.

Filament

Filament is the material with which 3D printers print, the same way copiers and printers use toner and ink.

Current filaments available:

Z-ASA Pro: Pure White.

Z-HIPS: Android Green, Grey, Natural White, Red.

Z-GLASS: Natural.

Z-PETG: Black, Grey.

Z-PLA Pro: Cool Grey, Gypsum White.

Z-ULTRAT: Pure Black, Red, Yellow.

For more information on the current filaments see Zortrax Materials.

Types of filament and price per gram:

Z-HIPS (All other colours): R2.50 per gram

Z-HIPS (Black): R2,46 per gram

Z-HIPS (White): R2,83 per gram

Z-ASA Pro: R2.95 per gram

Z-ULTRAT: R2,86 per gram

Z-GLASS: R2.51 per gram

Z-PLA Pro: R3.70 per gram

Z-PETG: R2.51 per gram

Steps to follow for 3D printing

Step 1:

Find a 3D model from a repository or make a 3D model by using computer-aided design (CAD) software. You can also find user-submitted designs at sites like Thingiverse, more sites are available under 3D Model Resources on the left. The 3D model must be in an STL format.

For 3D scanning, make a booking of the 3D scanner if you want to scan a physical object for 3D printing. Make your own file using the provided CAD software and Makerspace tools.

Step 2:

Use our online form (Jira Service Desk) to submit your STL file.

The STL file that is submitted must be an STL file without errors. If there are any errors SU Library or Makerspace staff may not be held responsible for any errors in printing.

Please provide the following information when submitting a 3D print request:

  • Type of Zortrax filament and colour from the listed filaments available.
  • Print quality (high/normal/draft).
  • Infill density (10-90%), shell or solid. Also mention the infill pattern type (excluding shell or solid option): Normal, Honeycomb or Octagonal.
  • Dimensions of the object if possible.
  • Student or staff number and email address.
  • Any special instructions in the Notes section.

The submitted file will be inspected to confirm that it is in the correct format.

Step 3:

A quote will be provided on the Jira Service Desk portal and payment can be made either via EFT or at Admin A. Upload proof of payment to the Jira Service Desk portal in pdf format. If you need a physical receipt, please pay at Admin A.

Step 4:

Remember to show your receipt when you come to collect the 3D print at the Makerspace. The Makerspace staff will communicate the collection date of 3D printouts through email notifications sent via the Jira Service Desk portal.

Step 5: 

Come and collect your 3D printout.

Prints are usually completed in less than a week, depending on the volume of requests. You will receive an e-mail when your print is ready to collect at the Makerspace.

Schedule one-on-one sessions for more information on 3D Printing or equipment, tools or design support. Select the Online Appointment tab to get started.

What is 3D printing?

3D printers build a three-dimensional object from a computer-aided design model. This is usually done by adding successive layers of printable material and so constructing the model. This is why it is also called additive manufacturing. Wikipedia.

A STL file stores information about 3D models. This format describes only the surface geometry of a three-dimensional object without any representation of colour, texture or other common model attributes. All3DP. 17 November 2016. Retrieved 5 May 2017.

These files are usually generated by a computer-aided design (CAD) program, as an end-product of the 3D modelling process. “.STL” is the file extension of the STL file format.
