How To: Get Started with 3D Printing

The Lou Duggan Creative Studio is open for business! And we're in the business of making things. This post comes from our Lou Duggan Creative Studio team. Check out more content and events here, opens a new window, anytime.


See it in 3D

Have you ever wanted to create an object but didn’t know where to start? Maybe it’s a keychain, a board game model, or a missing piece for something. You could try to buy it, but will it have that personal touch?

Enter 3D printing, an additive manufacturing process that allows you to design and print 3D objects for a variety of uses. Similar to a hot glue gun, solid material is melted and extruded layer by layer onto a heated metal plate where it solidifies to form a 3D object. The material used is often plastic, but some printers can print with metal, wood, or even chocolate!


3D Printing: The steps

  • First, get an idea! For your first-ever print, we suggest starting with something simple to get used to the ins and outs of 3D design and printing. Something like a keychain or a name plate. Once you get the hang of it, try creating something that will solve a specific problem; for example, a stand for a circular object to prevent it from rolling.
  • Next, you need a 3D model, which you can either design yourself with programs like TinkerCAD, opens a new window (it’s free!), or simply download a model from an online marketplace, like Thingiverse, opens a new window (also free!).
  • Now, you need to import your 3D model, which should be in .STL format, into a slicer software. There are different slicers for different brands of 3D printers, but they will all slice your model layer by layer into instructions for the printer to follow.
  • Finally, your sliced instructions (known as a .GCODE) are loaded into the 3D printer using an SD card, and it is ready to print! Simply load the filament, heat the print bed and extruder, then watch the printer get to work.

Come print with us!

To get started with 3D design and printing, check out the Lou Duggan Creative Studio at Halifax Central Library, where staff can help you learn the basics of creating your own 3D model and prepare it for printing in-house.

At the time of posting, the Studio boasts two 3D printers that community members can use for free, for prints under two hours in length. Drop by one of the weekly Creative Studio DIY: Makers Drop-In programs, or keep an eye out for one of our dedicated 3D Design and Printing workshops. We can supply laptops and provide guidance to ensure your prints are successful!

At the Lou Duggan Creative Studio, our aim is to foster the development of creative and digital skills in a community environment for makers of all skill levels. With our 3D printers, patrons can be empowered to create an object from start to finish, and feel a sense of accomplishment for having produced their own product.
