Use topology optimization to improve the design of a lightweight, 3D printed quadcopter.
Additive Manufacturing has opened the potential for design freedoms and performance objectives not possible with traditional manufacturing technics. Until now there has been limited software resources to fully unleash the design potential 3DP and AM allow for. Using Generate and traditional CAD modeling software, designers are asked to create an optimized quadcopter airframe design using constraint-driven design methodology.
The goal of this Challenge is to use topology optimization software together with 3D printing! While we will pick the best designs regardless of design software used, the judges will certainly pay a little extra attention to any topology optized designs submitted, so why not give "top opt" a try as part of your design process?!
Your entry must include:
2. STLs output (from Generate or other design software)
3. Screenshot of final design in design software (Generate or other)
4. If using Generate, link to the URL of your design
1. Must hold electronics, electronic speed controllers, motors, battery and payload in positions detailed in CAD file here: Quadcopter Design Files (with one exception - the distance between the battery and electronics is not defined and can be altered by you, the designer)
2. Max. mass of frame: 90 grams
3. Attachment mechanism of all components to the frame will be using adhesive-backed Velcro in order to easily swap components during testing. While there are no requirements for minimum surface area for this attachment, this is something to consider in your design.
4. Note: you do not have to use Generate to win a prize, you may use other topology optimization software or design the frame entirely in CAD. Generate is currently available only in the following countries: Austria, Belgium, Bulgaria, Canada, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, United Kingdom, United States.
Judging criteria: Judges will weigh a variety of factors but will place special attention upon the following:
- mass reduction from meta design space
- payload delivery
- flight for 50 meters and soft landing
- flight time
- ingenuity of design space(s)
- design aesthetics
- ingenuity of load case(s)
- use of topology optimization software
- ease of assembly, total cost, and print time

SUBMITTING AN ENTRY Only entries uploaded to GrabCAD through the "Submit entry" button on this Challenge page will be considered an entry. Only public entries are eligible. We encourage teams to use GrabCAD Workbench for developing their entries. Entries are automatically given the tag "TOPOPQUAD" when uploading to GrabCAD. Please do not edit or delete this tag. Only entries with valid tag will participate in the Challenge.
AWARDING THE WINNERS The sum of the Awards is the total gross amount of the reward. The awarded participant is solely liable for the payment of all taxes, duties and other similar measures if imposed on the reward pursuant to the legislation of the country of his/her residence, domicile, citizenship, workplace, or any other criterion of similar nature. Only 1 award per person. All judging decisions are final. All winners will be contacted by the GrabCAD staff to get their contact information and any other information needed to get the prize to them. All team awards will be transferred to the member who entered the Challenge. We will release the finalists before the announcement of the winners to give the Community an opportunity to share their favorites in the comments, discuss concerns, and allow time for any testing or analysis by the Jury. The Jury will take the feedback into consideration when picking the winners. Winning designs will be chosen based on the Rules and Requirements. Entry deadline is January 8, 2017 (11:59pm UTC). The finalists will be announced by January 30, 2017. The winners will be announced by February 15, 2017.
Update: - The winners will be announced in March.
SPEC REFINEMENT We want to make sure that you have all of the information that you need to tackle the challenge. As such, in the first week of a challenge we may refine the specifications or offer clarifications based on member feedback. Please ask any questions that you have!

Design submissions will be evaluated by a panel of experts, including Jesse Blankenship, CEO and founder of Frustum; Robert Wilson, president of Aerospace Advisory Group and former president and CEO of Honeywell Aerospace; and a member of the GrabCAD software organization.
Frustum is an innovative software company that is entirely focused on developing the latest functional generative design tools for designers through the Generate software platform. Generate empowers the mechanical designer to optimize and realize demonstrably better parts with Additive Manufacturing. Generate delivers a breakthrough cloud based optimization platform that brings design and topology optimization together as one. Designers now can advance their additive manufacturing designs in half the design and development time without any substantial learning curve. The timing has never been better for a solution to harness the power of AM.
