High resolution molds, sacrificial in aqueous media, obtained by vat photopolymerization 3D printing

From the synthesis of two methacrylic crosslinkers that contain in their structure β-amino esters activated for hydrolysis, photocurable formulations for vat photopolymerization have been prepared, in order to obtain sacrificial parts in aqueous media. Starting from binary formulations of both cross...

Starting from binary formulations of both crosslinkers with the monofunctional monomer poly (ethylene glycol) methyl ether acrylate (PEGMEA), its printability has been demonstrated, as well as the sacrificial nature of the printed parts. Selecting a crosslinker weight percentage of 15%, optimization of the mechanical properties of the printed parts has been carried out through a variation of the formulation components, combining the crosslinker with 1 or 2 monofunctional monomers chosen from 2-hydroxy ethyl acrylate (HEA), PEGMEA, methacrylic acid (MAA) and 2-carboxyethyl acrylate (CEA), in different proportions. All the formulations were printable, and have allowed for modulating the mechanical properties of the printed parts, in terms of rigidity/flexibility and resistance. All printed parts have been shown to be sacrificial in basic water. Finally, a proof of concept has been carried out for its possible use as sacrificial molds, to obtain screws from a thermoplastic poly (ε-caprolactone) and from a silicone network, obtained respectively by heating and chemical crosslinking, followed by solubilisation in aqueous media.The authors gratefully acknowledge support from the Consejo Su- perior de Investigaciones Científicas (CSIC).
