The purpose of this paper is to report on the development of a new type of sustainable material, limestone/polyamide12 (PA12) composite for Laser Sintering (LS). The material system is low cost, environmentally friendly, energy efficient, with good forming accuracy and mechanical strength.Different types of powder blends with different mixture ratios were created through mixing limestone and PA12...
A new type of sustainable material, limestone/polyamide 12 composite (LPA12), has been developed for laser sintering additive manufacturing that is low cost, environmentally friendly and energy efficient. The purpose of this paper is to study the forming accuracy, mechanical properties and microstructure of sintered LPA12 parts affected by different energy input, including laser power and part bed...
