 Karl--excellent post.  If I may, is the material now available for any "additative" manufacturing process; i.e. 3-D printing, stereo lithography, etc etc.  It certainly seems from your post the characteristics are very desirable and have definite applications.  Just a thought.

Chain orientation in feedstock before machining can have a large effect on final dimensions. Machining top surfaces of extruded plate can cause internal stresses to release causing warp on a previously flat plate.

Extreme accuracy and machining methods.

Mr Hebel has writtenn a useful article about the challenges found in machining some thermoplastics. All of the points that he made are certainly valid, and the suggested work-arounds will be helpful, no doubt.

But most of the challenges also exist when machining metal parts, except for the moisture absorbtion. The same tips apply when working to produce higher accuracy metal parts as well, although to a somewhat lesser extent. I just wanted to point that out to those who may need to give direction in the macchining of high accuracy parts.

Mr. Hebel, thanks for an interestnig article; you've given points that should apply to any thermoplastic, not just Duratron PAI.

The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
