Abstract
A three-dimensional printing kit can include a polymeric build material including thermoplastic elastomeric particles having a D50 particle size from about 2 μm to about 150 μm, and a fusing agent. The fusing agent can include water, from about 5 wt % to about 40 wt % lower alkyldiol organic co-solvent, and a radiation absorber to generate heat from absorbed electromagnetic radiation.
Claims18
A three-dimensional printing kit, consisting of:
- a polymeric build material consisting of thermoplastic elastomeric particles having a D50 particle size ranging from about 2 μm to about 150 μm, wherein the thermoplastic elastomeric particles are selected from the group consisting of thermoplastic elastomeric polyamide particles, thermoplastic elastomeric polyester particles, copolymers thereof, and mixtures thereof, and wherein the thermoplastic elastomeric particles include block copolymers with a polyol soft-segment block;
- and
- a fusing agent including water, from about 5 wt % to about 40 wt % of a lower alkyldiol organic co-solvent, and a radiation absorber to generate heat from absorbed electromagnetic radiation.
The three-dimensional printing kit of 1, wherein the fusing agent has a pH ranging from 9 to 9.3.
A three-dimensional printing kit, comprising:
- a polymeric build material consisting of particles of a thermoplastic elastomeric polyamide block copolymer with polyol blocks, the particles having a D50 particle size ranging from about 50 μm to about 80 μm;
- and
- a fusing agent including water, 20 wt % of 1,5-pentanediol, and a radiation absorber to generate heat from absorbed electromagnetic radiation.
