Sign in to use 3DPrinterOS at MIT
3DPrinterOS is a cloud service that allows you to submit 3D models to be printed on one of several 3D printers located at MIT CopyTech in 11-004. Sign-up is automatic when you log in with Touchstone using your MIT credentials the first time.
- Go to 3DPrinterOS at cloud.3dprinteros.com
- On the SIGN IN screen, click the SSO tab (SSO stands for Single Sign-On)
- Scroll through the list of SSO-enabled institutions and find the Massachusetts Institute of Technology button near the bottom of the list
- Click the button and go through the Touchstone@MIT authentication process, using your MIT username, password, and DUO two-factor authentication
- That’s it! You should now see MIT’s Project Manus 3D printers in your list of active printers, and are ready to create and send jobs
To print an STL file with 3DPrinterOS
- Sign into 3DPrinterOS at cloud.3dprinteros.com using MIT Touchstone on the SSO tab
- Click the UPLOAD tab in the top menu upload your .stl file; remember to select the Single file radio button
- Click SAVE AND GO TO MY FILES when the upload completes; you will see your uploaded file along with a few test files (various ducks)
- Click the orange LAYOUT button in the Action 2 column for your file to open it in the web-based STL Editor; in it you will be able to position , scale, and duplicate the part; make sure the part is fully positioned inside the print volume, and that you include supports if necessary or the print will fail
- Use the PRINTER button in the ribbon to make sure the right printer is selected (Dremel 3D45)
- When you are ready to proceed click the SAVE & SLICE button to start the slicer
- You can set layer thickness, infill, and other basic properties in the SIMPLE tab
- If you have experience tweaking advanced settings, you can find them on the ADVANCED tab
- When you’re happy with your settings click SLICE & TOOLPATH PREVIEW
- The TOOLPATH VIEWER window will open to show you how your part will look on the printer; you can use the height range slider to browse through your print layer by layer; by default, infill and supports will be shown, but you can toggle the Show infill checkbox to turn visibility off and on
- The Info panel in the TOOLPATH VIEWER window will show you estimated cost for your job
- Click PRINT in the ribbon to send the job to a printer
- In the SELECT A PRINTER window, you will again see the estimated cost of your job, along with a list of available printers that match the printer hardware you selected in the LAYOUT window; select the printer to send your job to, and if it is available now click PRINT, otherwise click QUEUE to add it to the queue
- When your part is done printing, you will receive email that it is ready
- Go to MIT CopyTech in 11-004 to pay for your part and pick it up
How much does the 3D Printing Service cost?
The cost for the service is a per-job $4.00 setup charge, $2.50 per hour of print time, and a material charge of $0.06 per gram. How long a job takes to print varies based on the model, your settings, and how you’ve laid it out on the build plate.
If a part fails to print, MIT CopyTech will contact you to let you know. We will not charge for failed prints and will make some suggestions on what needs to be changed if the model is not printable.
How to estimate the cost for my job
3DPrinterOS will estimate the cost of your job for you before you send it to the printer, in both the layout section and in the slicer. (The estimated cost will change depending on your layout and slicer parameters, which affect material use and print time) The estimated cost will also appear on your dashboard after you submit your job to the queue.
How to keep the cost down by planning your job
Many of the choices you make in how you scale and position your job, and the parameters you set in the slicer, will affect the cost of your job. Experiment with different settings. The slicer will accurately estimate the cost of your job as you change parameters. Find a balance between infill and wall thickness to give your part the strength it needs, without consuming material unnecessarily.
If you are printing several parts, one of the easiest ways to reduce the cost of your job is to combine as many parts as you can into a single job. Remember that each job has a fixed setup cost.
How do I pay for my print job?
When you pick up your 3D print you can pay via the payment methods accepted by CopyTech which include TechCASH, cash, and credit card. You can also use the MIT Mobius App to pay with TechCASH, including MakerBucks.
What materials are available?
Currently the printers we have are set up to print in PLA – Polylactic Acid. PLA is a biodegradable thermoplastic aliphatic polyester derived from renewable resources, such as corn starch or sugarcane.
What colors are available?
At this time, we are limited to the colors that are loaded into the printer which will usually be MIT red, white, light blue, or gray. The color of filament that is loaded into a particular printer will be shown in the printer list in 3DPrinterOS. We currently we have two printers operating in CopyTech so you can choose which printer to submit your job based on loaded color or based on the queue for the printer.
When will my job be done?
You can monitor your job’s progress from the 3DPrinterOS DASHBOARD tab at cloud.3dprinteros.com/dashboard. This will tell you where in the queue your job is, and after it has started printing will show you job status along with estimated and real print time.
You will receive several email updates from the 3DPrinterOS service, including a message to let you know when your job was sent to the queue, was sent to the printer, and completed printing.
