1st place: Sequential Five Speed Transmission by Terell Dunn
Terell is no stranger to winning design contests beginning with the State of Alabama Skills USA Mechanical Drafting Competition and then the Siemens Student Design Contest. He designed this model for a computer aided design class project at the University of Alabama. This transmission provided a warm up on the math and design that goes into the development of a transmission. He had to learn the intricacies of involute curves and other gear design mathematics that are used to design multiple sets of gears which will work together at a single center-to-center spacing. His design process is usually top down, or in this case, inside out. He started with the gears and finished with the transmission case. He used Solid Edge ST8 and Microsoft Excel on this project.
2nd place: Robotic Arm by Ricardo Espinosa
Ricardo created this robot arm as a training exercise that allowed him to better use the CAD features of Solid Edge ST4. He wanted to better understand complex surfacing, motors, sensors, and animation. The robot arm can grab rocks from one to 8 inches and up to 40 pounds.
3rd place: Balancing Bird by Allen Treadwell
Allen's inspiration for the balancing bird was to create a 3D printed item to give away to show the design abilities at The Advanced Manufacturing Center at the University of Maine where he works. The design process was as simple as creating lofts and then gently manipulating the sketches involved to get the proper center of mass. The fun part was in printing the first part, it balanced great. They use Solid Works for design. Allen is a licensed electrician with 37 years experience who helps design mechanical and electrical equipment for prototyping.
1st place: Scorpio Search and Rescue Recovery Platform by Winston Jennings
Winston's design experience includes a variety of industries from civil to mechanical to aerospace engineering. For the Scorpio S.R.P model he used SolidWorks to design and engineer the ultimate multi-purpose search and recovery drone. In SolidWorks he had to master the top-down assembly modeling to ensure the proportions of each component were just right and that there was no interference between them. Winston is inspired by nature for his designs and this was no exception being inspired by a scorpion. The way form follows function is his main theme when designing user friendly products.
3rd place: Star Wars The Force Awakens: BB-8 Droid by Sean LaVallee
On a day to day basis Sean creates steel structures like stairways, jib cranes, platforms, and more. In his downtime he likes to create non-steel assemblies to broaden his creative problem solving skills making him a better structural designer. This Star Wars inspired model was created with Autodesk Inventor.
Workstation CP350 assembly by Robbie Woolard
At Apex Conveyor Systems where Robbie is a mechanical engineer, they had to upgrade their manufacturing assembly line to improve production. This is the CP350 workstation assembly he designed for that project. Robbie used SolidWorks to create parts and sub-assembly 3D models.
Desktop fan by Winston Jennings
Using SolidWorks, Winston wanted to create something intricate with all the realistic details of his recently built desktop fan. He included everything from the jagged edges to some of the imperfect bends on some of the corners. Winston learned the sheet metal module of SolidWorks, plus in order to create the wiring and circuitry he had to experiment with splines, loft, sweep and more to get the results he wanted.
SMG .45 Caliber by Chris Dabek
A previous 3DX Model Showdown winner, Chris has been designing with Autodesk Inventor for 10 years. He likes target shooting so he chose to model this gun. He figured out how to use the 3D sketches feature to make springs.
iPhone 6 by Shubham Gupta
This is Shubham's first model upload to 3DX. He's a mechanical engineering student from Punjab who likes to learn new software in his spare time. When the new iPhone launched he knew he couldn't afford to purchase one so he did the next best thing, he modeled it! Since he was new to SolidWorks and KeyShot, it took him 23 hours to design & render the iPhone. He estimates he's learned so much in the process he could now finish this in 2 hours. Shubham is familiar with a wide range of design and engineering software.
Chess Set by Donald Anneken
Donald wanted to make a board and holder for the chess set he owns but needed a design. He started by reverse engineering the individual chess pieces. He says it wasn't terribly challenging, just time consuming to do the reverse engineering to work out the proper size for the storage unit. Donald has used a variety of CAD software in his career and now uses SolidWorks exclusively. Donald is retired from full time work, but still does some part time product design. He started in the industry as a mold designer in the pre-computer days. He then advanced to plastics engineer in the injection molding field where he was involved in product design, development and processing.
Aleksandar Andjelkovic - 3 Chamber Wankel Engine
Inspired by the challenge of a three chamber Wankel engine, Aleksandar created this winning model using Pro/ENGINEER Wildfire 5.0. In the process of the construction of the complicated middle chamber, he learned not only about the mechanics of the Wankel but also about modeling with Pro/ENGINEER. A freelance mechanical engineer specializing in 3D modeling, and recent member of 3DX, Aleksander likes to model assemblies as well as plastic devices.
Chris Dabek - Eric Whittle's V8
Inspired by Eric Whittle himself, Chris could not find a 3D model of this V8 engine anywhere online. He got hold of the prints and decided to see what he would have gone through creating this miniature engine. Using Autodesk Inventor® he learned how a lot of the constraints work, opening the valves, as well as closing them with the cam shaft, all just by rotating the crank shaft.
Martin Fitzgerald - Vespa Sprint
Martin combined his love of motor bikes, including scooters, with his preparation for his SolidWorks Advanced Surfacing Certificate to create this winning Vespa Sprint. It started as a simple frame but he decided to experiment and explore new techniques to push his drawing and modeling skills to the next level. The model was created using SolidWorks and rendered using KeyShot Rendering. Martin plans to model custom motorcycles, which we hope he'll continue to share with the 3DX community.
Daniel Gant - Radio Controlled Submarine
Daniel chose to make a radio controlled submarine to be used in testing high speed underwater controllability. He builds and flies model aircraft so an underwater vehicle was a new, but related area for him. Using many of the same techniques for designing and building model aircraft, Daniel used SolidWorks for this project. He went through several iterations before arriving at the current design. Using SolidWorks allowed him to test fit and finish before putting time and money into the physical model. The video shows just how well this submarine functions under water. Congratulations Daniel for the great model and really entertaining video.
Russell Richardson - Da Vinci Helicopter
Sparked by his interest in the tools used to rapidly go from idea to design, Russell was inspired to model Da Vinci's Helicopter. He imagined what engineers of the past could have created if they had the tools we have available today and the community of engineers sharing ideas around the world. Software used: SOLIDWORKS and SOLIDWORKS Flow Simulation for CFD analysis.
