Technology
At , we hold the utmost value in transparency. We'd like you to know that we have spent hundreds of hours researching, designing, prototyping, and testing our product to ensure that it fits all of your water-filtering needs.
Research
The 3-D filtration bottle was printed with polyethylene terephthalate glycol (PETG) because of its known pre-existing usage in the food and drink industry. The picture on the left displays our 3-D prototypes and test rings.

Materials
Below is a list of materials purchased online for the prototype:
​
-
Grayl™ Geopress Filter
-
Food-grade PETG for 3D printing
-
Epoxy Resin for waterproofing and gluing
-
UVC lamp (this was used for testing purposes only)
Dimensions
Inspired by the Grayl™ Geopress, the 3-D filtration bottle chambers and tests were designed and fitted to Grayl™'s filter cartridge.
Prototypes
After using Autodesk Fusion 360, Onshape CAD, and Ultimaker Cura to digitally plan the filtration bottle, the designs were then produced using Darren's Ender 3 Neo 3-D printer.
Epoxy
Shortly after printing, the 3-D designs were sanded down and cleaned with isopropyl alcohol. Then, combining resin and hardener to make epoxy, the mixture was coated onto the surface of the 3-D prototypes and thereafter let to rest overnight.
Tests
To replicate dirty water found in lakes and rivers, soil and sediment were added to tap water. After filtering this mixture using the prototype, water assessments were conducted to test measures including levels of alkalinity, ammonia, nitrite, and pH. Results showed that the filtered water was safe to drink
