Process

: Glowing Sphere

Glowing Sphere

The Cast was made with foam board using milling machine. Teflon was sprayed so that liquid resin doesn’t stick to the the foam. Bamboo fibers are randomly kept inside the foam and the form was closed and resin was poured from a hole from the top.

Bamboo fibers with Liquid Resin set to harden using mdf

The Resin hardened and got stuck to the board.

Transparent Epoxy Resin

: Transparent Epoxy Resin

MATERIAL: Epoxy Resin.
SCIENTIFIC NAME: Polyepoxide (epoxy resins are produced from a reaction between epichlorohydrin and bisphenol-A.)
Formula: C21H25ClO5
MATERIAL DESCRIPTION: Epoxy or polyepoxide is a thermosetting epoxide polymer that cures (polymerizes and crosslinks) when mixed with a catalyzing agent or “hardener”
In general, epoxies are known for their excellent adhesion, chemical and heat resistance, good to excellent mechanical properties and very good electrical insulating properties.

BASIC PROPERTIES
Compressive Strength: 85357095.2 N/m2
Tensile Strength: 56123324.3 N/m2
Stiffness: 81702873.9 N/m2
Density:
1100 – 1200 kg/m3 @ 25 oC ( typical)
Carbon Footprint:
Recyclable: Yes
Laser:
Small Laser: Yes
Milling: Yes
3D Printing: Yes
Advantage in Context of Digital Fabrication: Transparent resin is suited for models needing a good, smooth, quality surface with a transparent look. It can be easily molded and modeled to any given shape.
