The State of the Art of Material Jetting—A Critical Review

Abstract

Material jetting (MJ) technology is an additive manufacturing method that selectively cures liquid photopolymer to build functional parts. The use of MJ technology has increased in popularity and been adapted by different industries, ranging from biomedicine and dentistry to manufacturing and aviation, thanks to its advantages in printing parts with high dimensional accuracy and low surface roughness. To better understand the MJ technology, it is essential to address the capabilities, applications and the usage areas of MJ. Additionally, the comparison of MJ with alternative methods and its limitations need to be explained. Moreover, the parameters influencing the dimensional accuracy and mechanical properties of MJ printed parts should be stated. This paper aims to review these critical aspects of MJ manufacturing altogether to provide an overall insight into the state of the art of MJ.

New Methodology for Evaluating Surface Quality of Experimental Aerodynamic Models Manufactured by Polymer Jetting Additive Manufacturing

“…Many studies have investigated it for different AM processes. An optimal part orientation achieves good results [ 30 ]. In addition, the surface roughness of the 3D-printed parts can be affected by external factors.…”

Additively Manufactured Surgical Implant Guides: A Review

“…Material jetting functions in a similar fashion to a two‐dimensional inkjet printer. Material is sprayed onto the build surface, where it then solidifies, the build platform descends, and the process is repeated 60 . Because the system requires material to be deposited as a drop it is limited in the choice of material and so polymers and waxes are most commonly used 61 .…”

Biocompatible Customized 3D Bone Scaffolds Treated with CRFP, an Osteogenic Peptide

“…ABS and MED610 to fabricate 3D cylindrical implants to study their biocompatibility and osteoconductivity. These materials are fabricated with high resolution 3D printing processes to design complex structures to match the structure and mechanical properties of the bone surrounding the implantation site [ 42 , 47 ]. This reduces stress shielding in the implantation site [ 59 ].…”

“…Stratasys ® ’s MED610 material is also a non-biodegradable material which has shown biocompatibility compliance with ISO 10993 [ 46 ]. MED610 is fabricated using the polyjet printing process which generates layers of the 3D model by solidifying a photosensitive polymer resin [ 47 , 48 ]. The polyjet printing process results in high-resolution products (<20 μm) in comparison to conventional FDM printing (200 μm).…”
