PLA Light Weight is a specialized filament that allows its density to be adjusted using temperature.
It was originally designed for aeromodelling to make light weight aeroplane & drone hulls.
But it has been very successful as a casting pattern in lost wax style casting processes.
Initially, we used standard PLA for lost wax casting patterns.
But since PLA-LW is lower density, there is less PLA to burn out.
This makes much cleaner patterns & has far reduced ash in the process.
So whether its light weight components for general parts, or metal casting patterns, PLA LW is a great material.
