Shapelock (500g) - Safe Prototyping Plastic

Build your invention now -- without machine tools. Create super-strong custom parts, prototypes, and more!


With Shapelock, you can rapidly create mechanical prototypes, parts, brackets, housings, molds, etc. This amazing plastic melts in hot water and locks rigidly at room temperature! Super strong, tough, safe, and reusable!

ShapeLock is an Ultra-High Molecular Weight Low Temperature Thermoplastic, a super strong plastic similar to Nylon or Polypropylene in toughness. However, unlike the two former plastics it does not need high temperatures or high pressures to form into useful shapes. ShapeLock is easily hand-formed into shape at just 150 degrees Fahrenheit.

Key Features

  • Super tough, safe and non-toxic.
  • Machine-able - Easy to saw, drill, tap and mill.
  • Paintable - Readily accepts acrylic hobby paints, dyes, and pigments.
  • Excellent material for frames, brackets, forms, molds, and custom parts.

How to Heat ShapeLock

With Hot Water - Place granules in a hot water bath of 160 degrees Fahrenheit, when the material turns clear remove it from the water bath with tongs, allow it cool for a minute or two and then squeeze out any excess water. A standard kitchen thermometer is useful for maintaining the correct temperature. Do NOT Overheat.

In the Microwave - Larger masses of ShapeLock can be heated in the microwave oven. Be sure to place the ShapeLock in a bowl of water to limit heating of the material. Do not allow the water to come to a boil. NEVER heat ShapeLock by itself in the microwave. The material can reach very high temperatures and cause potentially serious burns if touched. THESE HIGH TEMPERATURES ARE NOT NECESSARY, SHAPELOCK BECOMES MOLDABLE AT JUST 150 DEGREES FAHRENHEIT.

With a Hot Air Gun - A hot air gun of the type used for heat shrink tubing or a hair dryer can be used to heat ShapeLock to its moldable temperature. Be careful not to overheat the material.
