Welcoming a New Generation of 3D Printers

06.06.2012 by Aaron Pearl

Here at Key Tech, we often use physical prototypes in our design process to literally get a feel for the part. While 3D computer models can be helpful, there is simply no substitute for actually holding a part in your hands and feeling it. 3D printing is often a great option for an initial prototype, especially for complex parts that are difficult to machine. Essentially, 3D printers work by printing many thin 2D cross-sections of a part on top of each other, bonding each layer to the previous one as they go. For more complex parts, special support structures may be required to keep the part from falling apart during the printing process, but the process is essentially the same.

Collecting very fine volumetric accuracy data

06.29.2010 by Chad Schneider

As part of the V&V test procedure, we designed a gravimetric means to characterize the volumetric and flow-rate accuracy of a couple of precision injection instruments. With this setup, we’re able to achieve measurement resolution of just 0.1 milligram and reduced the error due to water evaporation to 40 times better than using a mineral oil emulsion.

When To Do It Yourself

05.11.2010 by Chad Schneider

Whether to build a custom product or go with something off the shelf can be a tough decision. There are several factors to consider when shopping for off-the-shelf solutions, and cost is only one of them.

Starting Your Product Specification

12.15.2009 by Chad Schneider

Creating a detailed Product Specification is one of the most important steps one can take at the beginning of new product development. If the spec defines the entire sphere of possibilities, what needs to be included (and excluded) here?

Disruptive Innovation

10.12.2009 by Chad Schneider

Designing medical devices can be an expensive undertaking. It can cost thousands of dollars for a traditional setup to make microfluidic chips or a centrifuge to isolate the components of a multi-constituent sample. Luckily, the creative minds that are focused on solving complex, technical problems don’t stop working when there’s a tight budget.
