With the bamboo powder as a typical plant fiber powder, this paper studies the thermal bonding theory for the bamboo powder and the thermoplastic resin. With the appropriate hot melt adhesive powder, a theoretical analysis of the thermal effect of the thermoplastic resin bonding mechanism is made for the bamboo powder particles. The experimental study of the laser sintering characteristics of bamboo powder/thermoplastic resin composite powder is made for the bamboo powder mixed with the thermoplastic resin powder, focusing on the average mechanical properties of the SLS parts. The mixture of the bamboo powder and the thermoplastic resin powder is used to manufacture complex casting parts and SLS forming member. The infiltration wax casting dimensional accuracy of parts and transfer characteristics are studied.
