When are the ITLL printers available? |
Our Prusa MK4S printers are self-service, after you've taken the workshop, and available when the building is open.
The Markforged and Prusa XL printers are accessible via Fabrication Request and may incur a small fee. |
Building Hours and workshop sign up: https://itll.colorado.edu/ |
How to I gain access to the Prusa 3D printers in the ITLL? |
To use the printers, take a 3D printing workshop. |
Use this link to sign up for workshops: https://itll.colorado.edu/ |
I've taken the workshop and still see 'No Printers Available' |
You will need a clean log-in after taking the workshop to be able to see the printers. Try logging-out and logging back in. If that doesn't work, please see the 3DP engineer. | |
Can I use my own Filament? |
No, filament is pre-loaded onto the ITLL printers. | |
There is not enough filament to complete my project, can you change the roll? |
No, these printers are equipped with filament sensors which will automatically alert the ITLL staff that the filament needs to be replaced and will pause the print and re-start where it left off after new filament is installed. | |
How do I export files from OnShape or Solidworks for 3D printing? |
Be sure to export your file as an .stl and make sure that the units are millimeters. | |
Can I reserve a printer? |
Our printers are strictly first-come, first-served. You can see when printers are going to come available by checking the 'time' column when you press print.
Hot Tip: there is always a printer available at 8am. |
 |
Can I print with materials other than PLA and TPU? |
Not by yourself. However, you can submit a fabrication request to print in PETG or schedule a meeting with the 3DP Engineer if you are interested in other filaments and/or multi-filament printing. | |
How do I print with TPU? |
Make sure that you slice your file using the TPU settings and then use printer 10A which is dedicated to TPU. | |
Who can I talk to about my 3D Print? |
The ESS students at Launch Point should be your first choice for making sure you are optimizing your design for 3D printing. You can always make an appt with the 3DP Engineer as well before printing to chat about your design and how best to manufacture it. | |
How do I re-load my 3DPrinterOS balance? |
After your initial balance is depleted, you can use the ITLL website to re-load your account.
Once you have submitted the request, be sure to go back into the request and actually pay for it. Balance will not be loaded into your account without payment.
Be aware, it may take 24 hours for the balance to show up in your account so plan ahead. |
Go to: Requests -> Make a Request -> 3D Printing -> 3DPOS Balance Request
NOTE: Once credited to your account, credit must be used for 3D printing and can not be refunded. |
Can I get a refund on my failed print? |
Yes and No. We do not give refunds for all failed prints. We have accounted for a few 'learning' prints into the initial credit we give. However, if the machine has an unexplained layer shift while printing or there is a power outage during your print, we will be happy to refund any balance used. | Email the 3DP engineer with your name, printer that was being used and any other info to help them find the print in the system. |
How and Why would I use the Markforged or Prusa XL? |
The Markforged printers use a filament called Onyx which is a carbon inlaid nylon. This filament is used for high strength parts like gears, handles and higher temperature applications.
The Prusa XL can be used for larger prints that will not fit on the Prusa MK4S printers and also for Multi-filament printing (think TPU integrated into PLA prints...) |
To use either of these printers, you will need to submit a Fabrication Request through the Requests -> Make a Request |
Why is my print not sticking to the bed? |
There are a few things you can do to your file to help it have the best possible success. First, make sure your part is "on-bed" and not floating in space. Make sure the bed is freshly cleaned with isopropyl alcohol.
Add a brim to help it stick especially if you have sharp corners, lots of detail and/or lots of support on the first layer.
It's possible that it is time to swap hot ends. After you have made sure that the issue is not with your file, you can talk with an ESS student to see if swapping out the nozzle would be appropriate. |

Where else can I print? |
On Campus: Each campus makerspace has their own policies and procedure. Be sure to contact them to see if and how you can gain access to their spaces. Here are some nearby: |
Off Campus:
SolidState Depot (student discounts available) ExBuild (for higher definition printing) |
