- Olsryd 9 Cylinder Radial Engine (w/out cylinders)This Olsryd 9 cylinder is a quarter scale model of the Wright J-5 Whirlwind engine that powered Lindberg’s Spirit of St. Louis. This copy of the project does not include the cylinder and valve assemblies, which allows for a smoother Fusion360 experience when handling of the distributor, gearbox, driveshaft and crankshaft assemblies. Thus some of the renderings do not pertain to the model that you can find in this project. The full model with the cylinder and valve assemblies can be found here: https://fusion360.autodesk.com/projects/olsryd-9-cylinder-radial-engine The model was made by Casey Rogers, Carlos Oyuela-Mora, and Daniele Grandi from drawings that can be found here: http://www.olsryd.com/
- Shopbot Hybrid MachineCombined Additive and Subtractive Machine Additive manufacturing has come a long way in the past decade, specifically in the areas of FDM (Fused Deposition Modeling). We have seen astounding growth in methods, precision, materials, and speed. Still, certain instances occur where the desired combination of traits for a specific application aren't attainable in a single step. Here post processing such as vapor finishing, sanding, or even post machining have been used to help create parts that more fully satisfy the demands of industry. Post machining shows perhaps the most promise for creating engineering grade parts, due to the high level of controlled precision compared to the previously mentioned methods. It also it the only process which can increase the precision of a 3D print. Up till now post machining required a second highly sophisticated machine, with additional work holding and tooling. This is the issue which this project will attempt to address. Below are my comments on Pros and Cons of Hybrid Manufacturing. Pros Increased precision Because the printed object isn't repositioned, there is no uncertainty as to its location. The standard practice of touching off reference points can cause problems when using a 3d printed part is uncertain dimensions. Increased Throughput by Decreased Print resolution Parts designed to be post machined can be printed faster at lower resolution, then have critical areas machined to tolerance. These parts could be thought of much like a casting, where non critical areas remain rough while other precision areas are honed within the desired tolerance. Machined Internal Cavities At a high level of functionality, this machine could be capable of more than a 2 step process, machining geometry after any number of layers had been printed, accessing areas that would later be covered by additional material, Cons Increased Machine Cost, Weight, and Complexity Because the system must have the all the traits needed of both a 3D printer as well as a mill, there will be certain trade offs required which will likely result in greater weight and cost, while a head that can alternate between additive and subtractive processes will be more complex than a single purpose head. It is my opinion that the benefits mentioned above outweigh the potential detriments and obstacles presented by combining these two processes into one machine.
- Twisted vaseSo I downloaded a vase from thingiverse and was hoping my wife and friends would be impressed. They said I should have modeled a vase myself!!! Inspired by the vases modeled by user Zampik (http://www.thingiverse.com/thing:390713), I set out to make one of my own. I found the design incredibly easy with Fusion360. The print took around 20hrs and failed at least 5-6 times before I could figure out the optimal print settings! Wife loves it. I've included a walk through video for those who want to make a unique vase of their own. I also included the *.stl if you guys want to print mine.
- Santa's Jet-Powered SleighFor my holiday project I present "Santa's Jet-Powered Sleigh". The sleigh design was inspired by the movie "Arthur Christmas" I added the jet engines (based on a Rolls-Royce design), the fuel tank and carriage lights. The sleigh body and fuel tank was done in Solid modeling. The skis, jet engines and carriage lights were done in T-Splines. Renders done in Fusion 360 ray tracing and Cloud render. Have a happy holiday and all the best in 2015!
- Shreded skullsOk so a lot of people liked my vase that I made. This was done using a similar technique. You start out the same way as you would if you were making a vase (I posted a tutorial on the vase entry). Once you get a 360 set of t-splines you then place your favorite model on top of the splines, then do a intersect combine. what your left with is a shredded looking model! ... so that's the quick explanation. I'll have to post a video tutorial when I have more time! I have included 3 of the models for you to download or 3D print! If you guys have any questions I'd love to help. Thanks for looking!
