Abstract
PROBLEM TO BE SOLVED: To provide a method for manufacturing a carrier for tissue engineering, a carrier for tissue engineering, a method for manufacturing a porous body, and a porous body.SOLUTION: A method for manufacturing a carrier for tissue engineering includes: a powder layer formation step of forming a mixed powder layer formed from thermoplastic resin powder and a composition containing a light-absorbing agent; and an exposure step of selectively exposing the mixed powder layer to weld at least a part of the mixed powder layer, in which the powder layer formation step and the exposure step are repeated in this order to manufacture a carrier for tissue engineering having a three-dimensional structure. The average particle size of the light-absorbing agent is 1/3 or less the average particle size of the thermoplastic powder, and as for a light source used in light exposure, attenuation of light caused by passing of the light through the mixed powder layer is 5% or more, and attenuation of light caused by passing of the light through a single powder layer that is formed so as to have a thickness equal to that of the mixed powder layer and is formed from only the thermoplastic resin body is 40% or less.SELECTED DRAWING: Figure 1
