3D Printing Mingles with Micro

Propelled by materials advances, innovative techniques and performance improvements, additive manufacturing (AM) has come a long way since the days of experimentation for prototyping or consumer hobbyist applications.

BMF and 4D Biomaterials Partner to Bring Bioresorbable Materials to Micro 3D Printing

Boston Micro Fabrication (BMF), the pioneer in microscale 3D printing systems and UK-based 3D printing materials company, 4D Biomaterials today announce the capability to print micro-scale geometries using 4Degra® bioresorbable materials. This achievement marks the first time a bioresorbable material has been printed using micro 3D printing and will revolutionize the way implantable medical devices are manufactured in the future.

125 GHz Frequency Doubler using a Waveguide Cavity Produced by Stereolithography

This letter reports on the first Schottky diode frequency doubler with a split-block waveguide structure fabricated by a high-precision stereolithography (SLA) printing process. The printed polymer waveguide parts were plated with copper and a thin protective layer of gold. The surface roughness of the printed waveguide parts has been characterized and the critical dimensions measured, revealing good printing quality as well as a dimensional accuracy that meets the tight tolerance requirements for sub-terahertz active devices.

3D Printing For More Circuits

After several years of experimentation, and growing success in volume manufacturing for some use cases, technologies for 3D printing of electronic circuits are becoming more common. Some innovations in processes and materials are moving these technologies closer to mainstream electronics manufacturing.

Micro 3D Printing – The Ultimate Guide

The surging demand for miniaturized devices in electronics, biotechnology, automotive, and aerospace is putting increased interest in the development of microscale additive manufacturing technologies. This 3D printing method can produce tiny parts and components in shapes not possible with traditional manufacturing, faster and at much lower costs. Manufacturers 3D printing their own micro parts in-house are not effected by today’s supply chain disruptions.

A comparison of stereolithography, digital light processing and projection microstereolithography

Chuck Hull invented the first stereolithography (SLA) printer in the early 1980s and this led to the co-founding of 3D Systems, one of the leading companies in the 3D printing industry today. Since, there have been several variants of SLA, all fundamentally based on the vat photopolymerisation process. Namely using light to cure a photosensitive material. There are other polymer 3D printing methods, such as fused deposition modelling (FDM), material jetting (MJ) and selective laser sintering (SLS).
