3D Print an enclosure to protect an egg from a 15ft fall.
One of the most popular science activities for kids and first year engineering students is the "Egg Drop Challenge". To win the challenge, one has to create a container that will protect a raw egg from cracking or breaking from a high fall.
To make this a tougher challenge for the GrabCAD Community, we propose that the container has to be 3D printed. Let's see what type of creative solutions you'll be able to come up with!
To win, your submission must be:
1) Entirely 3D prited (FDM, SLS, SLA or PolyJet), and not require any non-3D printable parts.
2) Require minimal post-processing & make efficient use of material.
3) Effective in keeping an egg safe from a minimum drop of 15 feet (about 4.5 meters).
4) Be imaginative and creative.
5) Include a link to a video illustrating your use of the device.
6) Include instructions for assembly & use as well as a summary of inspiration for the design.
We will judge the designs based on the following criteria:
1) 3D printability - how easy is it to replicate your design with 3D printing? Efficient use of material, minimal post-processing (removing supports) and assembly time are all counted towards the final score. Remember, all of the enclosure must be 3D printable, and you can not use parts that are not 3D printed in your design.
2) Hight - your contraption must protect an egg from a drop of 15ft. However, the higher the drop your construction will survive, the more points you'll receive in this category.
3) Style. Ok, so you figured out how to 3D print a safe enclosure for your egg. But can you make the enclosure or the drop look good? You will receive extra points for a creative, original design.
To learn more about product design, visit GrabCAD blog.
You can find out about different 3d printing methods on the Stratasys website. Stratasys Direct Manufacturing has a great comprehensive overview of FDM (Fused Deposition Modeling), SLS (Selective Laser Sintering) as well as preparing STL files.
Once you master the fundamentals of 3d printing, check out "After the Basics: a 3D Printing Handbook".
Your entry must include:
• STEP/IGES
• Rendering of your design
• STL file format
• Description of the design assembly and inspiration for the design
• Video showing your design being tested (droped from 15 ft or higher) & results of the test
Technical requirements: Your design must be 3d printable via one of the widely available 3d printing methods: FDM, SLS, SLA or PolyJet. Please upload and check your file via one of the 3d printing services, to make sure that it can be printed. If you are printing the design yourself, make sure to upload a photo of the final design. Please upload a video of the test of your design (drop from 15 ft or highter), and results - did the egg survive?
Judging criteria: Judging criteria will be based on achievement of accomplishing criteria listed above, including: 1. Printability: ease of 3d printing the design. 2. Survival of the egg from a 15 ft drop or higher. 3. Style and creativity.

What materials are permitted?
Winston Jennings over 9 years ago
Size constrains?
Winston Jennings over 9 years ago
Does the device have to stay within a certain drop zone or can it be permitted to drop and roll away?
Winston Jennings over 9 years ago
This is a simple but technical design challenge!
Paul Miles over 9 years ago
Is the self-construction and video absolutely required to enter? Not everyone has access to a 3D printer. Any maximum size? Should the model be built to survive multiple tests, or just one successful drop?
Don B over 9 years ago
what about chickens?? what about the chickens??
lol
Nathaniel Andresmooi over 9 years ago
Egg drop container should survive drop? Its common in automotive to have crumple zones aka sacrificial parts that absorb impact. I would assume this container should be multi-use?
Robin Diekmann over 9 years ago
So only people with access to a 3D printer are able to compete?These things are expensive.. Well, at least it's an excuse to buy one, i've always wanted one for myself.
ZMA over 9 years ago
Shall the container be single-use, or it shall be re-usable for many "landings"?
Robin Diekmann over 9 years ago
Paulina Perepelkin that's true, The Netherlands is indeed a 3D printing paradise. Even the local phones/games/tv's/washing machines supplier sells 3D printers..
But again.. Great excuse to buy one! :)

I am from pakistan and i dont have access to any 3D printer and i want to compete is there any solution.
Ali Imran over 9 years ago
QADEER SHAH There are companies in Pakistan which will 3D print your design for you, for example:
marriala.net
print3d.com.pk
xplorer3d.com

Paulina Perepelkin Thanks ;)
Vagner Bachm over 9 years ago
Certainly the project Video requirement ready already disqualifies many good projects only because it does not have access to a 3D printer.
Don B over 9 years ago
I've seen many of the challenges.. A LOT of people will see the headline and immediately start working on it. Some brains probably work that way. As for the access to a 3D printer to complete this challenge...... I work at a college that uses an "educational only" copy of the program. I legally cannot win here (nor have I yet...lol). I still get involved to see other designs and learn more ways to inform the world around me that 3D printing is a huge feather in their resume. I love this stuff. I'm thankful that I can participate...

@ Don B I have access to 3D printers on a college campus aswell typically they will work with you if the machine time isn't already allocated. At most they might ask you to pay for filament. I would call this a design competition in which case it falls under education. You would have to ask if a design competition is permissible? Most education copy software doesn't block you from exporting an STL which is what you need to test a model.
Nathaniel Andresmooi over 9 years ago
Is the drop to be straight down landing on a hard surface? IE not sand a feather mattress water etc.
Hemant Chand over 9 years ago
Hi mam
Will the whole design be made just out of 3 d printed material or some other materials can also be added to the design like cotton and thing like that to keep the egg safe
Hemant Chand over 9 years ago
Hi mam
will the same prototype be tested by the judges for different height, what i mean is that if the egg is safe and the designed prototype has broken will the same prototype be used for the other height tests or you are going to take new 3-D prototype for the design
Bhavneet Singh over 9 years ago
i know i have knowledge that how can i protect that egg but for that i need some software to do that i have that software but its not installing in laptop so what can i do

Dear Paulina Perepelkin,
Hii, my concept is ready with design. On 21/07/16 i tried many(5+) times to upload the model. It didn't accepted my entry. Why it happened I don't know. Please, let me know the process to upload, if there?....
Nathaniel Andresmooi over 9 years ago
What kind of file are you uploading rahul?
Hemant Chand over 9 years ago
Hi sir, can you tell me what are the materials that will be used for 3D printing of our uploaded design, i am not able to find this information.
Nathaniel Andresmooi over 9 years ago
The two common printing plastics are ABS and PLA
Nathaniel Andresmooi over 9 years ago
It might be worth noting that judging criteria number one is printability. If you need an entire spool of filament the project should be impressive and need that much plastic? Either way it might be useful to make a max size for the project say about 100cm or 40 inches. This would stop someone from attempting an epic size parachute that might take weeks to print. Print time might be the better control. Max print time 48 hours?
Hemant Chand over 9 years ago
Can we use both the materials ( PLA and ABS) for printing the various parts of the design ?
Nathaniel Andresmooi over 9 years ago
Honestly I don't speak for Grabcad. I have printed lots of things with 3D printers though. I would assume yes you can use both? I would say you need to make an entire component out of one or the other though. Mixing the two plastics could be done with a dual printing head but most printers require a complete change over and a settings changes to print with either PLA or ABS. They run at different temperatures and sometimes different printing speeds. You can't lay down a layer of one and then immediately print with another. Also the cooling rates and the way the plastic warps differ. Stick to making a whole component out of one material to be safe. In this project I would suggest sticking to one plastic for the entire project unless you want to try to use materials properties in a special way. PLA is less brittle has more flex and warps less in cooling. ABS is slightly higher strength and more like glass harder and more brittle. ABS also tends to warp more during cooling. Polylactic acid (PLA), Acetyl-Butyl-Styrene (ABS)
Nathaniel Andresmooi over 9 years ago
@Paulina Perepelkin will there be video of some of the finalists drop tests? Also will the designs have to account for the different chicken egg sizes ie it will work with a JUMBO Grade AA egg all the way down to the smallest store bought eggs?

can the same model(not an assembly) have diiferent parts printed by different materials like rubber and plastic
QADEER SHAH over 9 years ago
And if anyone can tell me the major and minor diameter of egg ... i am considering the major as 55mm and wat bout minor .... help here please
James Matthew over 9 years ago
QADEER SHAH - I measured 43 at the minor diameter but it is difficult to know where to measure. Average length was 62.
Nathaniel Andresmooi over 9 years ago
@Paulina Perepelkin could we get an official set of egg dimensions? Preferably with some pictures and labels?
Either that or a statement saying the size of eggs will not necessarily be the same. Will need stretchy bending spring like or adjustable egg holders to deal with different egg sizes.
Nathaniel Andresmooi over 9 years ago
"Greater than 2 oz. or 56.7 g" Isn't really a dimension. So going to have to design adjustable or springyness to accommodate different size eggs. "ninja flex" is one soft printable material.

May we use hand cut filament? ie sections of printer material that haven't been printed. Or must it all pass through printer in one shape or another to be used in design.
Jonathan Brazeau over 9 years ago
a fun little challenge, we did something like this when I was in design school....
Sandeep sanwal over 9 years ago
what is the prize of the contest.
Nathaniel Andresmooi over 9 years ago
Paulina Perepelkin Yes that does. I know that there have been a couple designs using the raw filament as a material. Project must be entirely printed got it.
Bieber Alexis over 9 years ago
I did a drop test of 3 meters, and the Egg didn't survive.. This is a real challenge ! It survived 1meter with no problems. ( I will post a video of the failed drop test)
Bieber Alexis over 9 years ago
It was quite funny when the Egg exploded on the pavement !
Lance Skelly over 9 years ago
Paulina Perepelkin I tried several times to use the "Submit an entry" button on this page. It provides me only with a check box to accept the T's & C's, and a Save Button. No interface for uploading at all. Can one upload a design in the regular manner and add the relevant tag manually?
James Matthew over 9 years ago
Bieber Alexis - I agree, this is challenging. I just made a second attempt with a different design, with messy results. I think the chickens need to work on their egg design...
Raymond DeCarlo over 9 years ago
https://www.youtube.com/watch?v=nsnyl8llfH4 This will give you some good ideas.
My idea is just putting the egg in a balloon filled with enough helium or another light gas so that the egg falls slowly. It is a super obvious solution to a simple problem.
James Matthew over 9 years ago
Raymond DeCarlo - This challenge, however, allows only components that have been 3D printed. That makes balloons and helium unusable.
Bieber Alexis over 9 years ago
James Matthew - Yeah ! maybe a bigger shell would help ! :)

Paulina Perepelkin, it looks like the bug was fixed. Thanks.
Nathaniel Andresmooi over 9 years ago
Are there 3 successful drop test videos yet? Maybe extend contest if there aren't at least 3 successful videos uploaded? I won't be able to print an entry till the end of the month so even a two week extension would make the difference. Good luck to all those able to print and test.
Don B over 9 years ago
I'm just loving this challenge. Look at the entries.. wow. I posted this on my personal Facebook page to brag about you all. I think you all should also. We need to inspire young minds that their imagination is the only thing holding them back from being successful. Thanks to all.
Lauri Link over 9 years ago
I made some test if height is more than 20mm then natural egg will not surive without any additional parts :)
Lance Skelly over 9 years ago
Lauri Link, thanks for the science :) I think a few of us have discovered how fragile eggs really are. I dropped some of my contraptions from a height of 1m and the egg still broke!
BTW, I did some calculations and if you ignore air resistance, an object dropped from 4.6m (15ft) will hit the ground at 34km/h (21 mph)! Challenging indeed!
Fred Co over 9 years ago
Added photos and videos for my "Eggs-2" Skycycle Rocket, Minion BELLO(W) Rocket, and Bungee entries. Happy Monday.

"Scale: 1-10 for each category
Materials: any, as long as they were 3D printed!
Size contstraints: depends on the 3D printer you are using, as well as your design. If it takes longer to assemble but makes efficient use of materials and is able to get a 10 on style points, than a larger enclosure would make sense.
Landing: Landing is part of the style points. Does it look like a Romanian Gymnist upon landing? Or does it do a victory dance upon impact? Either would probably earn you 9+ points."

I vote for the rubber chicken (POLYGONAL CHICKEN), although she may need to borrow some big blades from the eggcopter (Eggcopter) to use as wings to slow her fall :)
I would also like to see some 3D print-only designs that could benefit from a multi-durometer printer (Ovulix v1.3 - GrabCAD Egg Drop Challenge, Egg Protector Case, and CUCKOO'S NEST, just to name a few)
