Week 4: 3D Printing & Scanning

About đź““

  • Group assignment: Test the design rules for your 3D printer

  • Individual assignment: Design and 3D print an object (small, few cm3, limited by printer time) that could not be made subtractively
  • Process ✏️

    I can’t wait to kick off 3D printing. As I plan to work on a hardware component, I definitely want to take steps towards my final project, a wearable for girls.

    That said, I’m still brainstorming the form factor:

  • A hair elastic / scrunchie?
  • Sports bra with heart rate sensor?
  • Shoe laces?
  • Anklet
  • Socks
  • 3D Prints: As of now and give him my current experiences I'm leaning towards creating a smart supportive sports bra. As a runner, and as I train for the New York City marathon, I have experienced a lot of chafing when it comes to my current sports bras. Additionally, I've also seen a variety of heart rate monitors that are attached to your chest.

    SO, my idea is to create a dual-support sports bra. The bra will provide both physical and mental support. As you run you're just supported and at the same time you will be collecting data that contributes to your overall performance goals. So how does this tie into what I'm 3D printing? well if I am working in the textile space which I never really have before I want to prototype on smaller size mannequins. It's imperative that I print small female bodies to test and iterate different form factors in materials.

    I have worked with 3D printers in various projects last year and I really enjoyed them. It's crazy to me that you can turn something in your mind into reality within just a matter of hours. I really want to try the Bamboo printer and experiment with different colors because my primary experience has just been manually painting on top of the copies.

    3D Scans: I used PolyCam to scan my shoe. I was impressed by the fideilty of my scan; however, my shoe was likely too complex for the details. I scanned on a the floor, and a lazy susan & tripod would have been much better to capture all of the angels on a stable surface.

    For this assigment, we tested the design rules for your 3D printer. It was interesting to understand how the wall thinkness, bridges, novel diameter impact the print and what we can accomplish. I found this Wiki Factory link to be really helpful in understanding the printer's functionality.

    Reflection 🤔

    I used the Prusa MK4 for my prints. That said, I was surprised by the “testing the rules of our printer” project. In previous projects where I've printed I've never really tested the limits and learned the capabilities of the specific printers in the Harvard engineering building in Makerspace. Usually it turns into more of a trial and error issue and project which ends up being a lot of hours of regret. now moving forward and having a deeper understanding of the limits and capabilities of these printers I think I'll be able to create more articulate prints and stretch the boundaries of 3D printers.

    As far as my three individual prints, the bracelet came out to scale. My two figurines were way too small to work with moving forward; however, they print quality was fantastic.

    I am fascinated by 3D scanning. I had never 3D scanned before, and I was impressed by the quality and resultion. Rather than modeling the intrecasies of shoe laces and individual details, I found the 3D print to effectively convert the physical to the digital.
