Microreactor Production by PolyJet Matrix 3D-Printing Technology

Abstract

This work investigates the methodology of producing a 3D-printed microreactor from the acrylic resin by PolyJet Matrix process. The PolyJet Matrix technology employs different materials or their combinations to generate 3D-printed structures, from small ones to complex geometries, with different material properties. Experimental and numerical methods served for the evaluation of the geometry and production of the microreactor and its hydrodynamic characterization. The operational limits of the single-phase flow in the microchannels, further improvements and possible applications of the microreactor were assessed based on the hydrodynamic characterization.

Analysis of Metrological Quality and Mechanical Properties of Models Manufactured with Photo-Curing PolyJet Matrix Technology for Medical Applications

“…Models made with PolyJet Matrix technology use additional material for support structures. They are formed by a separate group of heads, which can be removed using pressure washers, solutions or mechanical separation using water [ 22 , 23 ].…”

Research Progress of Self-Healing Polymer for Ultraviolet-Curing Three-Dimensional Printing

“…This paper mainly introduces the common dynamic bonds in UV-curing 3D printing polymers and evaluates the performance advantages and applications of different materials. [47] technique is also called PolyJet.…”

A Review on Additive Manufacturing of Micromixing Devices

“…Thanks to the use of this technology, it is possible to obtain 3D models or objects of different colours and hardnesses, with different properties and characteristics obtained within the same manufactured device [131][132][133]. During the manufacturing of these parts, it is necessary to use construction and support materials [132,134], although the latter may be removed.…”

“…Thanks to the use of this technology, it is possible to obtain 3D models or objects of different colours and hardnesses, with different properties and characteristics obtained within the same manufactured device [131][132][133]. During the manufacturing of these parts, it is necessary to use construction and support materials [132,134], although the latter may be removed. This action belongs to the post-processing and can be done manually (a few at the beginning, if it is possible) with the help of a water jet or by means of a chemical bath [135][136][137].…”

“…The aforementioned research has discussed printed microdevices in a single step to use them for different applications. Despite this, in [132], the authors tried to fabricate a microreactor with Polyjet, but instead of fabricating it in a single step, it was done in two steps, with one of the parts manufactured with a transparent material in order to ensure visible control. The printing process was completed in three hours, significantly shorter than the traditional approach with metal machining.…”
