Assignment 7: 3D Print It

Objective: Make something with the 3D printer.

Thoughts on how to accomplish this:

• Choose something that can be made in a resonable amount of time and with a resonable amount of PLA -- less than 8 hrs to start.
• Coordinate print jobs with others via Slack #cmstudio channel. Just share a message when you are planning to print and how long it should take.
• If you don't want to design something from scratch you can locate a model on Thingiverse to print. Again, pay attention to the overall scale, material, and print time. You should be checking this in Cura.
• Practice going through the CAD to Cura (Slicer) workflow to get familair with different parameters that affect overall print time and quality. Find a balance of time and quality this way.
• Report any issues with the printer or print failures via Slack.

Process for 3D Printing:

1. Save print ready STL from CAD
2. Load STL file into Cura
3. Choose PLA material for Extruder 1 and PVA for Extruder 2 (If using support material). Note: Using support material will increase overall print time.
4. Choose a print profile (ie. Layer Height: Start with Fast or Normal options. 0.2 mm layer height is a good resolution to start with. 0.1 mm layer height will double print times)
5. Choose an infill (ie. Density -- Somewhere beteween 20-40% is a good place to start for most objects)
6. Save GCODE file and copy to USB drive to insert into Ultimaker 3
7. Choose your file from the print menu and start the job. The machine will heat extruder 1 with PLA and heat the print bed before starting the print job.

Additional design resources for printing can be found under Design for 3D Printing. Look to the Ultimaker 3 support manual for any further details about the printing process.

Deliverable:

1. A physical 3d printed object(s). Bring object(s) to class. Take pictures of your object(s) to include in post.
2. In a blog post, describe the project goals, design process, challenges, and outcomes. Be sure to embed and include any supporting media and references to resources used.
3. Utilize any media necessary to explain your ideas. For example, diagrams, screenshots, screencaptures, renders, images, animation, and video.
4. (Optional) Export a mesh (STL File) of your model and upload it to Sketchfab (You will need to make an account). Once uploaded to Sketchfab, embed your uploaded model into your blog post. Here's a tutorial about how to do this. If you use a model from Thingiverse or another model source, just reference the website in your post.

Submit a link to your blog post on Slack #cmstudio.
