3D Printing Technology

03.01.2011 by Chad Schneider

There are three major rapid prototyping techniques for making plastic parts fast; layer building, low-pressure molding/casting, and machining. Each has its advantages and drawbacks, depending on how you intend to use the part. Let’s start with the various layer-building processes.

Key Tech presents at the Johns Hopkins Medical Device Startup Tool Box Day

12.15.2010 by Andy Rogers

Want to start-up a medical device company? Key Tech attended the Johns Hopkins University’s “Medical Device Start Up Tool Box Day” to explain why having an experienced design engineering partner in your “tool box” is key to your success.

Resources for tinkerers

07.08.2010 by Chad Schneider

Are you a tinkerer? For those of us that are concerned about how best to crack open a $1,000 MacBook with a critical soda problem yet have the compelling desire to take it apart anyway, there is help.

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.

Do I really need to know this?

06.01.2010 by Chad Schneider

Those “core” classes in college may seem superfluous when trying to tackle an engineering curriculum, but I’m grateful that I was exposed to topics like business, philosophy, and psychology.

What are your mechanical and electrical rapid prototyping capabilities?

03.02.2010 by Chad Schneider

Key Tech accomplishes prototyping by leveraging a network of approximately three dozen prototyping vendors, selecting the method and vendor based on the best match to your application. Multiple suppliers keep us current with the state of the art technologies and allow for flexibility and speed in the prototyping process.

The symbiosis of modeling and prototyping

02.23.2010 by Chad Schneider

Prototypes are essential to testing system performance. However, due to the current technological constraints of creating microscale prototypes, compromises in the characteristics of the prototype usually must be made, which can lead to unforeseen, expensive problems on the production line. Fortunately, basic, fundamental models of significant aspects of the system (first-principles modeling) can be “calibrated” through the use of focused CFD models and empirical data. The result is improved models that allow the designer to bridge the knowledge gap between paper and production.

Born with questions

Is asking the right questions something that can be taught, or do you have to be born with this twisted skill?

Why is ISO-certification good for a design firm?

12.22.2009 by Keith Lipford

Without robust design processes, it is all too easy to lose track of critical design issues – the consequence of which is usually schedule delays, added costs, and/or undesirable design compromises.

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?
