During your onboarding project and as we are in the manufacturing phase of Battery Box, you will be A LOT of 3D printing. I remember being confused the first few times, so we’ve put together this simplified guide.

Before printing, make sure you have the following softwares downloaded:

1 - Create/Open your 3D object using SOLIDWORKS

Typically, you will use the 3D CAD (computer-aided design) software SOLIDWORKS to create and open your 3D objects. If you have not worked with SOLIDWORKS before, I recommend this video SOLIDWORKS 2020 tutorial for beginners to get started

2 - Save your 3D object as an STL File

The STL file is what stores the information about your conceptual 3D object, and is the file type that allows your 3D design to be read in a Slicer software

3 - Import the STL File into a Slicer and save it as G-Code

A Slicer is a software translates the STL file into G-Code, which is printing instructions for your 3D object. In the Slicer, decide on the size and placement of your 3D object. Rule of thumb, make sure to align your 3D object so its flat (and typically largest) side touches the print bed first:

Once you are finished, save your model as G-Code

4 - Print!

Save the G-Code onto the printer’s SD card. Make sure to correctly calibrate your printer. If you’re using one of the Prusa printers at RPC, follow this video: Original Prusa i3 MK3 guide for a new user

Common Issues when 3D Printing

If you run into an issue when starting your 3D print, that’s okay! Below are 3 common issues we’ve occurred while 3D printing and how to best deal with them:

1. Issues with 3D printing the first layer

Filament not sticking to bed

Applying Elmer’s glue to the 3D printing bed to help with bed adhesion. If there are still issues with bed adhesion, try printing the first layer at 70% of the printer’s normal speed

2. Incorrect Nozzle height

If you notice this issue while printing the first layer of your print, adjust the Z-axis height of the printer nozzle accordingly until the nozzle is at the most optimal height:

3. Not enough support

Open your STL file in the slicer again, and either change your 3D object’s orientation in the slicer, or add supports to your 3D print before printing again

4. Prints getting stuck to the printing bed

A bit of rubbing alcohol + enough applied force should do the trick to unsticking those stubborn prints.

Congrats! Depending on the size of your 3D object, your print will finish in a matter of minutes or over several hours. Feel free to message @Donna Kim @Shem Kim @Nicole Choe if you need additional assistance or have any more questions. Happy printing! : D
