Our event was part of the eSTEAM Camp at KHEPRW Institute, Tech Trek - Robotics, Game Making, Makerspace.
Attended by about 25 people.
KI staff: Pambana Uishi, KI Office Manager and camp leader; Keenan Rhodes, Makerspace supervisor
Campers: local youngsters aged 9 - 15
IUPUI professor Andres Tovar and 4 of his students
OSCE Days 2016 - 3D Printing.pdf (813.2 KB)
Introduction to OSCEDays
Last year about 30 cities, only two in US: Chicago, Indianapolis. This year about 70 cities, 6 in the US: Chicago, Indianapolis, Denver, Los Angeles, San Francisco, Seattle
What is Open source - many know and use to open source software, there is less understanding about open source hardware and OS concept, in general
What is circular economy - KI Aquaponics is an example, it is an closed-loop exchange and eliminates waste.
OSCE tries to bring humans in balance with our ecosystem.
Why should we care? We are setting our planet on fire. We need to rethink how we do stuff, how we use stuff.
We should avoid creating any waste. Create things that others can pick up and use. Plastics do not degrade. Plastic particles now in air, oceans.
3D can create a lot of plastic waste. Let’s choose to use biodegradable materials.
3D printing is serious business: prototype, objects that can be used at home.
ABS is oil based and does not degrade. Other more sustainable are coffee, beer, bio based, hemp.
There is a lot of new technology that youth can be a part of.
Open-source is sharing information, technology, building knowledge through collaboration and transparency.
Key message: use 3D printing to make useful things, things you need, biodegradable and share your knowledge.

He talked about design models and the different types of printers he uses, one of them is open source hardware and he prefers it. Passed around money clip, bike chain, battery cover, pyramid, paper clip, chess piece, that got the campers very interested.
Talked about how you get into 3D printing. If you like to design can use CAD free software.
Get a printer. Design, try, you will have failed prints, re-try, learn from others, use open source.
Showed failed and success print of Statue of Liberty. Prosthetic for dog, shell for turtle.
Shared new technology used to scan objects and get 3D images. 3D printing
Kyle also donated a few plastic spools, that his ABS filament supplier does not take back, for the campers and KI interns to find a re-use for, a direct application of circular economy principles.
Questions - do you feel a lot of heat from the printer? No. As the camp printer was working, printing a door hook, he also remarked does there is no smell of melted plastic, because it uses plant-based filament.
What do you make at your facility?
Auto console. Speed monitor panels. A lot of different things, some confidential.
What would be the career path? Engineering or industrial design. Difference between the two: the designer wants it to look good, impressive, original; the engineer wants it to be makable, functional and cost effective.
- Andres Tovar Projects
Talked about additive manufacturing (adding material instead of removing it). Working on making more efficient plastic injection molding and using recycled ABS plastic.
Talked about design challenge for a car that is lightweight, absorbs energy and withstand the impact of a crash.
Showed IUPUI’s FREE MATLAB® program that solves topology optimization problem in 3D and some of the tutorials for campers to explore.
He also Showed how 3D printing is used in medicine, in making better-fit prosthetics, for example.
Public session ended. KI campers were then challenged to use Selva 3D to convert an image of a useful household or everyday item to 3D for printing. Campers worked in teams to select an item and upload it to Selva 3D. They will use the Flashforge Creator printer and Biome3D, a plant-based plastic filament that comes on a biodegradable spool.
