Assembly fit test prints for upper dozer blade. Printed at the High Speed setting. The top piece is the rear of the dozer blade and frame. The middle pieces are the lift arms. The bottom piece is the front of the dozer blade and frame. (Image links to Flickr photostream.)

1/16th scale radio control U.S. M9 ACE Armored Combat Earthmover project:

Outer portion of road wheel assemblies 3D printed in both grey HIPS by eSun and white n-vent by taulman 3D for comparison. Took a while to get the hang of the n-vent filament. (Image links to Flickr photostream.)

This is the outer portion of what will be one of the road wheel assemblies. It was modeled in Inventor for 3D printing. (Image links to Flickr photostream.)

1/16th scale radio control U.S. M9 ACE Armored Combat Earthmover project:

This is the outer portion of what will be one of the road wheel assemblies. It was printed on a LulzBot TAZ 5 using grey HIPS by eSUN. I will be making some minor adjustments to the geometry and then reprinting it in white n-vent by taulman 3D for comparison. (Image links to Flickr photostream.)

Being a full-time employee and a full-time student has left no-time for much of anything else. In the next three weeks, I will be wrapping up courses in AutoCAD, MicroStation, and SolidWorks. Next semester, I will be starting two more courses in AutoCAD and one in Creo. In the four weeks between semesters, I plan to post some updates on the state of the CAD files and a few parts taken to physical prototype.

I have posted three new simple motion-test 3D animations of the M9 ACE design file to YouTube.

I am in the process of porting the design files originally created in NewTek’s LightWave 3D, and entertainment 3D software, to Autodesk’s Inventor, a CAD 3D software. This is necessary in order to have files optimized for the manufacturing process. To this end, I have been working to bring myself back up to speed with both Autodesk’s AutoCAD and Inventor.

In addition, I am close to completing an Engineering Design Graphics with Mechanical Specialty degree, which means I am also attempting to learn the applications connected with my courses, including Bentley’s MicroStation, PTC’s Creo, and Dassault Systèmes’ SolidWorks.

As you might imagine, this does not allow a lot of free time. It also makes it that much harder to keep commands straight from application to application, slowing the whole process a bit. However, I have a rare week more or less free to focus on creating part files.

As it happens, I took a little of that free time this evening to explore the web, and came across a company that offers low-run manufacturing services including injection molding, CNC machining, and 3D printing. This looks like a promising alternative to the manufacturing options I had been exploring previously. I hope to be able to have prototype parts to show and test by the end of the year.

In the meantime, I have posted two simple motion-test animations of the M9 ACE design file to YouTube. I plan to post two more by the end of the week.

M9 ACE blade animation test

I will post more details as they become available.

As a post script, this site, KH3D.com, will now focus specifically on the radio control tank projects and eventual product offerings. The portions of this site that deal with my personal projects and interests will begin moving to KurtisHarris.com.
