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

BOSTON and NOTTINGHAM, United Kingdom, Dec. 7, 2021 /PRNewswire/ -- 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.

Aimed at creating biocompatible and bioresorbable micro-scale medical devices, the joint innovation has a variety of applications and opportunities for medical device manufacturers and innovators, ranging from micro-scale rigid orthopedic devices and fixations through to micro-scale soft tissue applications.

The partnership combines BMF's innovative projection micro-stereolithography (PµSL) approach with 4D Biomaterials' 4Degra resin inks which together will help to solve design and biocompatibility issues for medical device manufacturers, opening up new opportunities for implantable devices and improving patient care.

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.

As AM gains traction for full-scale production use cases, the technology is evolving to conquer another new frontier: The production of micro-scale parts that were previously out of reach with conventional 3D printing technologies.

Demand for micro-scale parts is booming as products gain complexity and decrease in size to accommodate a smaller footprint. In the heath care sector, for example, there is evidence of more miniaturized drug delivery devices, wearables on a chip and hearing aids. At the same time, the myriad chips, arrays and sensors that power electronics devices, defense equipment and new generation of semi- and fully-autonomous vehicles are also rapidly contracting as they gain sophistication and empower innovative use cases.

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. The 62.5 GHz to 125 GHz frequency doubler circuit comprises a 20 m thick GaAs Schottky diode monolithic microwave integrated circuit (MMIC) in the waveguide. The measured doubler provides a maximum output power of 33 mW at 126 GHz for input power of 100 mW. The peak conversion efficiency was about 32% at input powers from 80 to 110 mW. This doubler performance is compared with and found to be nearly identical to the same MMIC housed in a CNC-machined metal package. This work demonstrates the capability of high-precision SLA techniques for producing sub-terahertz waveguide components.

BMF strengthens its team with Ferenc Toth

Boston Micro Fabrication (BMF), a pioneer in 3D printing systems for micro fabrication, is adding Ferenc Toth, an experienced 3D printing sales expert, for further expansion in Europe, particularly in Germany, Austria and Switzerland. The new Sales Manager DACH/Europe will be available as a contact person at the Formnext trade fair in Frankfurt from Nov. 16 to 19, 2021.

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.

Christopher Tuck, professor of material science at the University of Nottingham, observed that what’s particularly attractive among the many different processes and materials used for additive manufacturing (AM) is the ability to build up one layer at a time, which increases design flexibility. That results in improvements in performance and heat management, plus the ability to optimize component architectures.

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.
