3D PRINT ESSENTIALS
RHINO QUICK START
To print on the Prusas, you must process your .stl file through a downloadable freeware called ‘PrusaSlicer’. In here you are able to rotate and arrange your pieces for printing, it is always recommended you rescale in Rhino, to avoid any parts becoming too small to print correctly. PrusaSlicer is free to download from Prusa’s website.
1. SET UP THE MACHINE:
Below is a step by step guide on how to set up the machine.
2. SET UP THE PRINT:
CHOOSING THE LAYER DISTANCE:
Find below an example of the same model printed at 3 different distance settings and with the same infill percentage. The distance between layers can affect greatly the print time.
3. CHECK THE PREVIEW
When happy with the setup of your print, preview it by clicking on the “Slice” button on the right-hand side of the screen. This will generate a preview of your job, allowing you to review the print layer by layer, see how the supports and brim look, as well as tell you exactly how long it will take to print (this will also be the total price as we charge £1 per hour). You are able to zoom in and see how the details of your model, you can easily change any of the settings before you save the project by going back to the settings panel and updating whatever settings need to be changed and re-slicing.
4. SAVE AS
Once you are happy with your model. Go to 'File' and save your project. You need to name it in a very specific convention: DSxx_w1234567_DavidScott_3D1_3MF .
DSxx = your course. For example, if you are BA Interiors it would be BAIAY3, or BA architecture could be BA_DS3.2.
w1234567 = your student number
DavidScott = your name
3D1 = type of file and the number of files, sequentially. If you have 3 files you will have 3D1, 3D2, 3D3
3MF = the file format. Prusa exports as a 3MF.
WE WILL EXPORT THE G-CODE FROM YOU PRUSA FILE!
We have five Trotec laser cutters, they are named Mies, Jorn, Alvar, Zaha and Liz. They have important differences:
Zaha and Liz are 100w and they are also bigger than the other three, their bed size is 1000mm x 610mm. Their only limitation is that they do not cut MDF.
