You will see the Files page by default when you first log in. If you navigate elsewhere, return to this page by clicking Files at the top of the page. You may need to click the Projects button to see your previously uploaded files.
You will notice that you will have several demo models already loaded into your account. These are examples 3DPrinterOS adds to your account when you sign up. You can always delete these files at a later time if you’d like.
To add your own file, go up to the top right hand corner of the screen and click the Add Files button.
A window will pop up allowing you to select your .stl file. To do this, you can either drag and drop the file into the gray box, or click the select from computer button that appears in the middle of the screen.
While your .stl file uploads, a progress indicator will appear on the left side of the page.
Now your file will appear in the list with the other examples files.
Now you will need to prepare the .stl file for printing. On the right hand side of the file listing, you will see two different actions that you can take. They are Layout, and Slice. Before slicing your .stl, you need to adjust how it is positioned on the build platform by select the Layout action.
This opens a new window that lets you adjust how your model sits on the build plate of the printer. You also have options to Move, Scale, or Rotate the object if you need to change how the object is oriented in order to minimize supports that are added during the the slicing process. You can also click Add File to bring additional objects onto the platform. This is helpful when you have multiple small parts as it helps to keep them organized and helps to optimize printer efficency.
While you can choose to use or not use most of the tools in this window, there are two that must be checked before you slice the print. They are the On Bed and Center tools that you will see on the right hand side of the window. First click the On Bed button.
This will make sure your model is sitting flat on the printer and not hovering above or below the bed which will likely cause your print to fail. Next click the Center button.
This will bring your model to the center of the build plate which helps to reduce the possibility of print warping that can occur if the object is out near the edges of the platform. If you have multiple objects on the platform, you will also need to use the move tool to adjust them so they don’t overlap or touch. Once you have made sure that you object or objects have been positioned, you can go ahead and click the Slice button at the top right of the window.
This will bring up the Slicer Settings window that takes your .stl file and cuts it into layers, adds print supports, and creates the .gcode file that the 3D printer reads to create a 3D printed object.
The three settings that can be changed are Layer thickness, Shell thickness, and Infill percentage. To make things easier, we have loaded a Recommended (PLA) slicing profile based on print settings that Maker Commons has found to be a good balance between print speed and efficient filament usage. If you’d like to change these settings, it is better to do so on a second version, or iteration, of your print so you can compare how the settings have changed your object. Otherwise, all you really need to do on this screen is click the Slice & toolpath preview button in the bottom right of the window.
This will convert your .stl file to a .gcode print file, optimized for our Dremel 3D45 printers, and bring up a preview window that lets you see how your model will print. It also estimate how many grams of filament your 3D print will use.
When you are finished looking at the preview, just his the Close (X) button in the top right of the window.
3DPrinterOS now switches over to the Projects folder page of your account. Here you will see three files associated with your model. One is your original .stl model, the second is your original model but with the layout changes that have been made. It has the same name as your model with an additional numerical string added to the name. The third file is the .gcode (Dremel 3D45) file. This is the file that you submit for actual 3D printing.
On the right side of this file, you have two different actions that you can choose. They are Preview and Print. Clicking Preview returns to the previous window, where you saw the simulation of how your model will print and the filament estimate. To submit your model for 3D printing click the Print button.
Now you need to select a print Queue for submitting your model.
For personal Prints, select the Maker Commons Personal Submission Request Queue by clicking the radio button on the right hand side of the print queue. If your model is for a class, please select the Maker Commons Class Submission Request Queue.
Once you’ve selected a printer, the last step is to fill out the print delivery label form.
Your Penn State Email Address, First Name, Last Name and Delivery Campus and Delivery Method need to be filled out correctly. If this information is incorrect, your 3d print delivery may be delayed. The Delivery Campus location sets the Campus Library that your print will be delivered to. If you are choosing World Campus, this option is currently only available to mailing addresses in North America. It is also not available for University Park or State College addresses. You will also need to select the Delivery Method to be World Campus or it will not be delivered. If you have any questions, please contact us.
When you are finished and have verified your delivery information, click the Continue with Queue button. A notice appears in the bottom left of the screen letting you know that you’ve successfully submitted a print.
Now that you have submitted a 3D print, your filament credits will be debited at $0.10 per gram of filament. You can always see your balance by looking at top right hand corner of the 3DPrinterOS website. If you are running low on filament credits, more can be requested at: https://makercommons.psu.edu/3d-printing-information-1/request-additional-3d-printing-credits/
