The issue of residual stresses in additive technologies [PDF]
MATEC Web of Conferences, 2023 The paper considers the issue of residual stresses in 3D-printed plastic models. Most additive technologies create residual stresses in products. Residual stresses occur in the printed material due to its expansion when heated and contraction when cooled.

Digitally fabricated ribbed concrete floor slabs: a sustainable solution for construction
RILEM Technical Letters, 2022 The concrete used in floor slabs accounts for large greenhouse gas emissions in building construction. Solid slabs, often used today, consume much more concrete than ribbed slabs built by pioneer structural engineers like Hennebique, Arcangeli and Nervi.
