A blog documenting the my Covid-19 face shield creation process.
First off, happy July 4th! We can see some eratic firework displays from our window, even in the heat of this time. Anyway, I have been working on finalizing the product for final display and sales. Right now, I have two more hurdles I need to cross before reaching a level where I can start …
I finally found a good source for elastic bands. This roll should cover my needs for the foreseeable future, or at least until I get these 500 parts out. Here is the plan. Assemble around a hundred and get them to hospitals around the Athens, GA area. After that, I am planning to start mass-producing …
I need to make a decision. The elastic at the back of the mask can be one of three materials, each with its pros and cons. A. Rubber Band Price per Part: Link Pros: Cheap, Easy to Sanitize Cons: Look Cheap, Might be Uncomfortable if Worn For Long Periods of Time B. Velcro Link Pros: …
Here we have it. More than a month after starting this project, I finally have the finished product! It has been a long time in the making, and I have dreamed of this completion. I finally got the visors from Mr. Kwon from Fabrico. Exactly 500 priced at 60 cents apiece, equating to a grand …
Finally I got something for the visor sorted out. I contacted multiple manufacturers, scoured plethora of hardware for the raw material, and finally got something together. The problem I faced were numerous. Purchasing the raw materials (a PET plastic roll) online was simply to expensive per part. I tried to find a similar product in …
After spending some time with these frames, I have a few improvements I would have made if the design of this project was left to me. First, the front assembly has a solid infill in the forehead grip. This wastes plastic, instead I would have opted for a hollow design. Second, if the frame had …
I met with Mr. Moxley today. He was really helpful, and I learned a lot from this visit. Not only did he graciously provide 360 quantities of the frames that I was looking for, but took me around to look at the machinery, and their inner workings. Injection molding is quite an interesting process that …
I was originally planning to make a single-cavity, injection mold with my father’s 3 axis CNC machine, and provide that to a workshop. They would, in turn produce the frames, and I could get up to thousands a week. But in my research, I found Underwood Molds. It turns out that they were already producing …
From yesterday’s research, I compiled a list of all the local plastic production shops. I got their numbers and location from google after searching “plastic injection molding near me”. I then called all of them up, and created a spreadsheet. A screenshot is attached below. I listed the number of the company, the time it …
Today was my first delivery. I delivered about 35 parts, 15 from last week. When my father put on one of my 3D printed parts, some of the excess extrusion scratched him. He noted that the part was not smooth, nor would it be comfortable to wear for a long duration. I started looking for …
