From whey robocasting to custom 3D porous carbons

Additive Manufacturing, 2022
We describe how robocasting and carbonisation of partially dehydrated whey, a surplus of the dairy industry, produced 3D porous carbons with custom morphologies.

Sintering and robocasting of β-tricalcium phosphate scaffolds for orthopaedic applications

Acta Biomaterialia, 2006
beta-Tricalcium phosphate (beta-TCP) scaffolds with designed, three-dimensional (3-D) geometry and mesoscale porosity have been fabricated by direct-write assembly (robocasting) techniques. Concentrated beta-TCP inks with suitable viscoelastic properties were developed to enable the fabrication of the complex 3-D structures.

Characterization of 100Cr6 lattice structures produced by robocasting

Materials and Design, 2017
Lattice structures of 100Cr6 steel are fabricated from metal-based ink by robocasting using Pluronic F-127 solution • The proposed ink formulation promoted sintering of printed parts • The optimization of the heat treatment allowed to reduce the porosity in the printed parts • Interesting mechanical properties are obtained both at a local level and at ...

Mechanical properties of calcium phosphate scaffolds fabricated by robocasting

Journal of Biomedical Materials Research Part A, 2007
AbstractThe mechanical behavior under compressive stresses of β‐tricalcium phosphate (β‐TCP) and hydroxyapatite (HA) scaffolds fabricated by direct‐write assembly (robocasting) technique is analyzed. Concentrated colloidal inks prepared from β‐TCP and HA commercial powders were used to fabricate porous structures consisting of a 3‐D tetragonal mesh of ...

Impregnation of β‐tricalcium phosphate robocast scaffolds by in situ polymerization

Journal of Biomedical Materials Research Part A, 2013
Ring‐opening polymerization of ε‐caprolactone (ε‐CL) and L‐lactide (LLA) was performed to impregnate β‐tricalcium phosphate (β‐TCP) scaffolds fabricated by robocasting. Concentrated colloidal inks prepared from β‐TCP commercial powders were used to fabricate porous structures consisting of a 3D mesh of interpenetrating rods.

Controlling properties of ceramic formulations for porcelain robocasting

Ceramics International, 2023
Porcelain pastes (PlotPastes) were formulated to be used on an additive manufacturing (AM) process (material extrusion) process, primarily robocasting (R3D) technique. The material morphological and thermal characteristics were evaluated by scanning electron microscopy (SEM), differential thermal analysis (DTA) and thermogravimetric analysis (TGA). The

Robocasting of dense yttria-stabilized zirconia structures

Journal of Materials Science, 2017
Advanced ceramic materials with complex design have become inseparable from the current engineering applications. Due to the limitation of traditional ceramic processing, ceramic additive manufacturing (AM) which allows high degree of fabrication freedom has gained significant research interest. Among these AM techniques, low-cost robocasting technique

Robocasting of alumina hollow filament lattice structures

Journal of the European Ceramic Society, 2013
Abstract Robotic controlled deposition (robocasting) of an aqueous colloidal α-Al 2 O 3 gel for manufacturing of cellular ceramics with periodical lattice structure was investigated. The colloidal gel was loaded with 50 vol% α-Al 2 O 3 and exhibits shear-thinning behavior, a shear modulus of 288 kPa and a yield-stress of ∼700 Pa.

Micro- and macroscopic design of alumina ceramics by robocasting

Journal of the European Ceramic Society, 2017
Abstract The manufacturing of alumina ceramics with auxetic and macro-cellular lattice structure and with textured microstructure was achieved by using robocasting and TGG-technique (Templated Grain Growth). After sintering at different temperatures a grain growth effect was observed in robocast ceramic filaments, which showed a microstructural ...
