Minnesota Technical Symposium

MMS Logo AIChE Logo ACS Logo Minn Mass Logo

MinnTS is an annual joint meeting of area technical and scientific organizations. The first meeting was held in March 2003 and was sponsored by four participating groups: MMS, SEMI, AVS and ASM. By 2005 the number of participating groups had doubled to eight. To read about the upcoming events for each sponsoring society click here

MinnTS was started for the purpose of providing a venue for local technical professionals to get together for networking, dinner, and technical presentations given by local experts. The speakers are deliberately chosen from the local area to avoid travel expenses and minimize costs for the participating organizations. In some cases speakers from outside the area have been able to combine an appearance at MinnTS with scheduled visits to area businesses. Because of the wide diversity represented by the sponsoring organizations, the speakers are chosen to present a range of general interest topics. Click here for previous speakers & topics.

Introduction to 3D Printing
What is 3D printing? What is the technology inside the printer? What do people make? Amy's presentation will focus on an overview of 3D printing, focusing on fused deposition model (FDM) type printers and Stratasys technology. This presentation will outline the different technologies and then show how current Stratasys customers are utilizing it from day to day.

3D Printing Functional Materials & Devices
McAlpine Talk

The ability to three-dimensionally interweave biological and functional materials could enable the creation of devices possessing unique and compelling geometries, properties, and functionalities. Indeed, interfacing active devices with biology in 3D could impact a variety of fields, including regenerative bioelectronics, smart prosthetics, biomedical devices, and human- machine interfaces. Biology, from the molecular scale of DNA and proteins, to the macroscopic scale of tissues and organs, is three-dimensional, often soft and stretchable, and temperature sensitive. This renders most biological platforms incompatible with the fabrication and materials processing methods that have been developed and optimized for functional electronics, which are typically planar, rigid and brittle. A number of strategies have been developed to overcome these dichotomies. Our approach is to use extrusion-based multi-material 3D printing, which is an additive manufacturing technology that offers freeform, autonomous fabrication. This approach addresses the dichotomies presented above by (1) using 3D printing and imaging for personalized, multifunctional device architectures; (2) employing 'nano-inks' as an enabling route for introducing diverse material functionality; and (3) 3D printing a range of functional inks to enable the interweaving of a diverse palette of materials, from biological to electronic. 3D printing is a multiscale platform, allowing for the incorporation of functional nanoscale inks, the printing of microscale features, and ultimately the creation of macroscale devices. This blending of 3D printing, functional materials, and 'living' platforms may enable next-generation 3D printed devices, from a one-pot printer.
