Abstract

Solar Heater and 3D Printed Molds utilizes 3-D printing capabilities and the energy produced from the Sun to heat and re-purpose crayons, candles, and other waxes. The Solar Heater is constructed out of common waste stream items and up-cycles them into a useful and interesting design whose main function is further up-cycling. This design was created in the Humboldt State University Engineering 215, for the client, SCRAP Humboldt whose goal is to “inspire creative reuse and environmentally sustainable behavior by providing educational programs and affordable materials to the community.” [1]

Background

Engineering 215 is a design class at Humboldt State University that, each semester, partners with a local community business to improve student experience and to improve the business partner. For the 2013 Spring Semester, Engineering 215 has partnered with SCRAP Humboldt, a non-profit organization that promotes creative reuse and up-cycling. Team SuperStar's (pictured right) goal, and challenge, was to design a 3-D printed object that would add value to the waste stream. And that's what really makes the Solar Heater and 3D Printed Molds different from other designs; it utilizes 3-D printing. Molds for crayons and candles were created using the 3-D design software, AutoCad.

Problem statement and criteria

There are to many common household items that are going in to the waste stream and no solutions that take advantage of 3-D printing.

Criteria Constraints Weight (1-10)
Aesthetics Does not look like trash 7
Reusability Ability to transform waste into a solution 9
Replicability Possible to replicate at home 4
Durability Able to last 6 months 1
Cost Make as least costly as possible 8
Size Be mobile 1
Materials Greater then 75% recycled 10


Description of final project

The Solar Heater and 3D Printed Molds encourages reuse of crayons, candles, and other waxes. The parabolic wax melter pulls common items out of the waste stream and continues to utilizes their designed/natural properties. The two main components of the design are the satellite dish, which focuses the energy from the Sun to melt the wax needed, and The 3-D molds which are designed to be unique and resemble local themes.

Costs

The costs of the project was extremely low due to the fact that many of the items used were donated or salvaged. However, anyone attempting to recreate this project will most likely be able to construct it for around the same price. The high price items are common in the waste stream and should be easy to obtain or have donated.

Testing Results

The final Wax Melter with 3D Molds product accomplishes exactly what is designed to do. It is able to transform old broken wax items into new, fresh looking products. The Wax Melter with 3D Molds completes this impressive task in a fairly reasonable amount of time (depending on the weather).

Discussion and next steps

The overall goal was to design something that can take items out of the waste stream and transform them into an object that can do another task. Our design not only pulls common items out of the wast stream, but it puts them to work in preventing other items from entering the waste stream. As far as application goes SCRAP Humboldt has already come up with the idea to use this design to teach children about reuse and sustainability.
