Upon acquiring new lab space in Yellow Springs, I have wanted to expand Form5’s equipment allowing research to continue in new directions. After two years of printing and prototyping with our Ultimaker 2 (which was just revamped), I knew it was time to go big or go home in the 3D printing department.

This summer I’ve been researching many different printers on the market, I continue to read great things about Creality 3D’s ‘CR-10’ 3D printers and how they open they are. So I dove further and discovered that the brand Creality 3D provides a large scale 3D printer with a build volume of 500x500x500mm and it was in my budget. The ‘CR-10 S5’ would allow Form5 to print large prosthetic sockets and continue researching with finer recycled filaments. I anticipate research and projects in fabricating large scale prosthetics in the next year and with the limited build volume, my Ultimaker 2 has, I saw this being a very affordable option to raise the bar.


Alas, this was such a great 3D printer and the timing was right, although it did come with its own twist. The ‘CR-10 S5’ isn’t assembled in the box, meaning I would have to assemble an entire large scale 3D printer one-handed. So after collecting recyclables, making filament, and building prosthetics arms, I am now equipped to building 3D printers. IMG_6101

Form5’s ‘CR-10 S5’ arrived last Thursday and I spent most of the weekend getting it assembled. Although I have pictures of the progress, I still have much more fine tuning to conduct before trying the big stuff. As you can see it is a HUGE 3D printer and I am looking forward to getting it set up in the new lab. Creality claims the ‘CR-10’ can be assembled in 10 Minutes, but take it from a one handed guy; TAKE YOUR TIME! Also, the directions for this printer were quite disastrous. I ended up using several Youtube videos on the assembly for the regular ‘CR-10′. I wasn’t too concerned with the assembly part of the printer, I had my doubts with wiring and getting it to print. Truth be told I had a rough start with my Ultimaker for quite some time. I actually ended up taking two days to fully build the “CR-10 S5’. Not only do you have to assemble the structure, but also have to do some “simple” wiring.


When it came down to wiring, it was incredibly helpful that the videos on Youtube were corresponding with the ‘CR-10 S5’, in addition, the connections all had tags/labels. Finding all the connections was probably the most one-hand friendly part of the process. I was also advised to tighten all gears and stepper motors before printing. I loaded the 1.75mm PLA filament that came in the box and began learning the settings to prepare for my first test print!

The printer comes with a Micro-SD card and with its open operating platform, I am able to use Ultimaker’s Cura software to slice files. I decided to substitute the traditional Creality cat print and went with a Squirrel to print instead! I had a mishap with the alignment of the print which I have learned is a loose belt (this can be seen in the squirrels upper body). I am continuing to fine tune and work with this new printer and am getting closer to “dialing in”. I look forward to showing you more progress and updates as our road to Yellow Springs grows closer!

Big things ahead,
