Cover Story: This paper demonstrates a novel microfluidic device fabrication technique by combining a 3D printing and Polydimethylsiloxane (PDMS) process. A Digital Light Processing (DLP) 3D printer is used to fabricate both a master mold for the PDMS process and a substrate containing pneumatic ports. A microfluidic device with complex structures such as a taper structure was successfully fabricated and demonstrated.View this paper

Automated Quality and Process Control for Additive Manufacturing using Deep Convolutional Neural Networks

Received: 24 November 2021;  Published: 28 February 2022;  doi: 10.21926/rpm.2201005

Abstract

Additive Manufacturing (AM) is a crucial component of the smart manufacturing industry. In this paper, we propose an automated quality grading system for the fused deposition modeling (FDM) process as one of the major AM processes using a developed real-time deep convolutional neural net [...]

Material Challenges and Opportunities in 3D Printing for Hip Implant Applications

Received: 16 November 2021;  Published: 23 February 2022;  doi: 10.21926/rpm.2201004

Abstract

There is a current need for tissue and organ repairs, replacement, and regeneration for patients who suffer from diseased or damaged tissues or organs. This situation is continuously on the rise and the supply of this form of therapy does not meet the patients demand mostly due to lack o [...]

Life Cycle Assessment (LCA) of Wood Flour and Pellets for Manufacturing Wood-Plastic Composites (WPCs)

Received: 07 December 2021;  Published: 09 February 2022;  doi: 10.21926/rpm.2201003

Abstract

This study is expanding the previous studies that were focused on the material properties and transportation costs of the two alternative feedstocks for manufacturing wood-plastic composites (WPCs): wood flour and pellets. Besides the material properties and cost analysis, life-cycle ass [...]

Fabrication and Demonstration of a 3D-printing/PDMS Integrated Microfluidic Device

Received: 21 October 2021;  Published: 25 January 2022;  doi: 10.21926/rpm.2201002

Abstract

3D printing is an attractive method to fabricate microfluidic devices due to (1) its fast and simple process without specialized equipment and cleanroom environment, and (2) its capability to create complex 3D structures. Combined with Polydimethylsiloxane (PDMS), it can be used to devel [...]
