 3D printing is a great way to turn your creative ideas into tangible objects. ​ Whether it is to make a quick prototype of a novel clothes peg, some funky new earrings or to replace a broken part of your favourite fishing rod, 3D printing provides you with the technology to easily do this. 3D printing is a great way to turn your creative ideas into tangible objects. ​ Whether it is to make a quick prototype of a novel clothes peg, some funky new earrings or to replace a broken part of your favourite fishing rod, 3D printing provides you with the technology to easily do this.
  
-To print something out in 3D, you will need to take a couple of steps before you can hit the print button. First you will need to create a 3D model and save it as an STL file – a file that contains all the information about the object’s shape. Then you will need to use some software to turn that model into a format that the 3D printer can read.  This format is called GCODE and you use a slicing software package to produce. This file can then be printed out.  Sometimes the objects comes out of the printer looking a little bit rough on the surface and you can for instance sand the surface ​for it have a smoother finish. Each of these steps will be discussed in more details ​below.+To print something out in 3D, you will need to take a couple of steps before you can hit the print button.

-Before you can start, you will need to create a digital model of the 3D object you want to print. ​ Models can be created using a 3D modelling software package. There is a very large selection of software to choose from, but to start off with we recommend TinkerCad.

 The Internet is another great resource for finding 3D models. Sites like [[https://​www.thingiverse.com|thingiverse]],​ [[https://​www.yeggi.com|yeggi]],​ [[https://​www.pinshape.com|pinshape]] or [[https://​www.youmagine.com|youmagine]] have large libraries of designs that other people have created and shared. ​ These sites are a great place to find inspiration,​ to find existing designs for projects that you are working on, or for people who are just starting out and are a little apprehensive about using 3D modelling software. Most of the models on these sites can be reused under a creative commons license, or can be bought for a small fee.  The Internet is another great resource for finding 3D models.

-If you want to print a copy of an existing object, ​then you can use a 3D scanner ​to create a digital model of that object. Unfortunately,​ at this time, we do not have any 3D scanner available at the Noosa Library Service Makerspace.+If you want to print a copy of an existing object, ​and have access to a 3D scanner ​you can create a digital model of that object. ​
  
-With your 3D model saved, ​make sure you save it as an STL file, you are now ready for the next step.+With your 3D model saved, as an STL file, you are now ready for the next step.

 After the print is done, you will have to remove any rafts/brims and supports that were added during the slicing of the 3D model. ​ The best way to do this is to use needle nose pliers or small sharp cutters. You can use a small file or a sanding block to remove any last little burs. After the print is done, you will have to remove any rafts/brims and supports that were added during the slicing of the 3D model. ​ The best way to do this is to use needle nose pliers or small sharp cutters.

 ==== Safety ==== ==== Safety ====
 Working with 3D printers requires some caution, as parts of the printer, such as the nozzle and print bed can reach temperatures well above 200°C and can take a while to cool down.  Printed objects can also have very sharp edges. For this reason it always a good idea to wear gloves when removing the print from the print bed. When you remove the finished print from the printer bed and while removing rafts and support materials it is advised that you wear safety goggles, as small parts of filament break off easily and can cause a threat to your eyes. Working with 3D printers requires some caution, as parts of the printer, such as the nozzle and print bed can reach temperatures well above 200°C and can take a while to cool down.  Printed objects can also have very sharp edges.
