3D Printing in the FabLab
Make a model in 3D software and ensure it exports to STL
Export the file to STL, ensuring it fulfills the requirements
FabLab looks at your model and slices the STL
FabLab emails you with the price of the model
You approve the cost before it gets printed
Once the cost is approved, the model gets printed
You receive an email once it’s ready for pick up
Create Your ModelYour model can be created in any software you like, but you need to ensure it can export to STL (stereolithography) format. STL is a specific file format that is supported by 3D printers. Some examples of software that export to STL include:
Export to STL
A hollow model means the interior of your object is not solid. Making your model hollow is the #1 trick to making your print cheaper and turnaround faster.
Semi-solid models have interiors partially filled. Some 3D printers allow you to customize the density, ranging from 0 to 100.
Solid models have interiors completely filled, are stronger and harder to break. These models tend to be more expensive than hollow models.
The bed size refers to the size of the printer bed. This is the surface your model gets printed on and it won’t print if it exceeds this size.
Refer to http://mactech.sheridanc.on.ca/fabrication for the 3D printers and their bed sizes.
Make sure you know exactly what size your model should be and in which measurements, otherwise you might end up with a print that’s too big or too small.
Water tight refers to models that contain no holes or unstitched surfaces, creating a solid body. Ensuring your model is water tight is critical so that your print does not give you different results or fails completely.
Submitted files must be less than 1mb. Large file sizes take a long time to download and slice, and sometimes won’t even print.
File size too large? Simplifying your model and reducing the amount of polygons it contains will significantly minimize your file size.
Laying your print flat or changing the orientation can produce better results and save time while printing.
Does your model have any overhanging parts? Overhanging pieces of 45 degrees or more require support material.
SubmitThe submission form can be found at http://mactech.sheridanc.on.ca/fabrication/submit/
Take accurate measurements of the length, width and height of your model when you submit it to print.
SliceAn STL (stereolithography format) file is mathematically sliced and oriented in the software. Each slice is a single layer of plastic, and is laid out one after the other.
Slicer software is needed to convert STL files into a language understood by printers. Slicer software does literally what it’s called – it chops up the STL model into thousands of flat 2D layers that the 3D printer can then print into a physical object.
Cost3D prints are $0.75 per gram, including material and support. The FabLab will contact you via sheridan email or SMS. When you submit your file, you request your preferred contact method.
ApprovePlease add the appropriate amount of funds to your account.

PrintPlease speak with a Mactech if you'd like to see your 3D print in process. Prints may take 3-4 business days to complete and class projects may take a bit longer. Models are also grouped and as such, may take longer than the suggested print time in 3D software.
Please note, printer malfunction will not be charged to you. Build corruption, incorrect scaling, and incorrectly formed builds will be charged to you. Please use your software's preview to ensure you are printing what you desire
