Particle Bed Technique for Hempcrete

Danché, V. / Pierre, A. / Ndiaye, K. / Ngo, T. T.

This study focuses on the particle bed additive manufacturing of hempcrete. The micronized hemp shives play an important role on the imbibition phenomenon during the 3D printing process. It appears imperative to control the key parameters involved in the imbibition process of the powder-bed. The measurements and analysis of the depth and homogeneity of the imbibition front are carried out in this study.

We highlight that diffusion coefficient and the imbibition kinetic are clearly influenced by the amount of hemp in the powder bed. This study highlights that micronized hemp shives reduce the imbibition kinetics due to its swelling.
