Waterproofing 3-D prints from the makers
- epoxy coat after or purpose made 3DP coating-- add commercial versions here:
- thicker layers, more perimeters,solid, smooth chemically https://www.fabbaloo.com/blog/2017/10/19/waterproofing-your-3d-prints
- For chemical smoothing can use results from this paper for any type of 3DP material Chemical Compatibility of Fused Filament Fabrication-based 3-D Printed Components with Solutions Commonly Used in Semiconductor Wet Processing

Using Coating as a waterproofing Technique
Coating and Lamination
Singa, K.A review on coating & Lamination in Textiles:Processes and Applications,American Journal of Polymer Science,2012
- Polyurethane (PU) is used to waterproof clothing
- Perfluoro, Polyacrylates, PVC, and Vinylacetate are chemicals used as coatings for waterproofing
- Butadiene Polyurethane resin is also used as a coating to waterproof objects
- Direct and transfer coating are best for waterproofing

Using 3D prints
3D Printed Underwater VR
Zhang, W. Tien Tan, C. Chen, T. Demo: A safe Low-cost HMD for Underwater VR Experiences, Mobile Graphics and Interactive Applictions, Article 12, 2016
- 3D printers are able to print parts that are waterproof
- Specific density and infill settings are needed
- Can 3D print components that prevent leaks

Underwater Homes
Champion, B. Jamshidi, M. Joordens, M. 3D Printed Underwater Housing, World Automation Congress (WAC), 2016
- Polylactic Acid (PLA) absorbs water since it is bio-degradable
- Acrylonitrile Butadine Styrene (ABS) is a stong material
- ABS does not absorb water so no coating is needed
- ABS can be smoothed by a coating of acetone which prevents leakage
- Waterproof seals can be a flat seal, O-ring, or gasket
