The 3D Hydroponics System Challenge

Medium

The goal of the 3Dponics challenge is to create an eco-friendly and original 3D-printable gardening part that can be used with one of the existing 3Dponics systems to make it as efficient as possible.

The demand for locally grown, organic food is at an all-time high. However, buying organic can be pricey and not everyone can afford it. A better option is if you could grow exactly what you need in the comfort of your own home, even if you do not have a huge garden or any outdoor space.

3Dponics has created a series of 3D-printable hydroponics systems that allow people to do just that. All of our DIY gardens are green technologies that attempt to minimize energy use, recycle everyday materials (e.g. empty plastic bottles), and leave the smallest environmental footprint. This is also what makes 3Dponics so accessible and appealing to everyday people.

Now, we are encouraging GrabCAD users to draw from our inspiration and come up with more eco-friendly gardening hacks for our 3Dponics gardens. Whether you improve upon an existing 3Dponics part or you come up with your own from scratch, the ultimate goal is to create something that encourages sustainability and efficiency, but that remains accessible and easy for the average person to assemble.

The key is to think outside the box and remember all of the different applications of 3Dponics… The systems are used not just by gardeners and greenthumbs, but also by teachers in STEM education, urban farmers, professional chefs, and even astronauts for space farming.

And remember, the simplest ideas are often the best ones.

You can download existing parts from the https://grabcad.com/3dponics-1/projects profile on GrabCAD.

About 3DPONICS

Based in Ottawa, Canada, 3Dponics Inc. is a fresh, new tech lab that’s uniting two exciting worlds—3D printing and hydroponics—to create 3D-printable gardens that allow you to grow your own food without the use of toxic chemicals or loads of energy.

3Dponics presents a realistic solution to a number of today’s problems, from the rising cost of produce and food insecurity to climate change and space farming. It is also an incredibly valuable teaching tool in today’s K-12 classrooms, which are becoming increasingly focused on science, technology, engineering and math (STEM).

At 3Dponics, our ultimate goal is to fuel innovation by giving people the tools and opportunities to apply their knowledge, skills and creativity to meaningful, and potentially world-changing, projects.

We want to empower you not just to imagine the world of the future, but to create it. And that’s exactly why we’ve started this GrabCAD Challenge. If you like what we’re doing and want to join us, enter the challenge and make a difference!

    one thing i don't understand for the Drip system: the solution is in costant dripping on the first plant: drop to drop h24 7/7 ?

    Hi James, great question! The quick answer is yes, PLA is food-safe. For a more detailed explanation, you can check out the 3Dponics forum - https://www.3dponics.com/vanilla/discussion/4/is-3dponics-safe-for-use-around-food-what-about-toxic-chemicals-in-the-3d-printing-materials

    Hi Simone, it depends on what you're trying to grow, since different plants require different amounts/types of nutrients. The best is to monitor the health of your plant and adjust the drip according to that. If you find that your plants are not responding well to constant dripping (24/7), feel free to turn off the pump.

    Is the somebody who have found some good 3d model of bottles here on grabcad. Could be nice to be able to get the thread right. Plus it would be nice to have it for size and render as well. Hope you will share your findings.

    Hi Asbjørn, I'm not sure about 3d models of bottles, but you can try our 3Dponics Customizer that basically allows you to customize the drip nozzle to fit any size of bottle. It works with other 3Dponics parts as well. Here's the link: https://www.3dponics.com/software/3dponics-customizer/

    I agree! Worse and worse challenges. Is there anybody that value work and ideas, not only to try to get something free of charge?
    It'll be good if GRABCAD team would pay attention on it.

    Anja Pujic ,just a generic question,

    for the drip system: does not the last plant (near the floor, just to understand) take the "taste" of the 2nd and the 1st one?
    If the drops fall into the middle plant, and feed it, then drip again into the other, is not the final taste compromised?
    it is just a curiosity of mine

    Even if this challenge is on a voluntary basis, $100 of credit for the winner it is totally stupid. It's worse that to give nothing, it is a total lack of respect.

    Hello Simone, its often recommended that you should plant same kind of plant for different levels in the same system. The reason is, we have to add fertilizer / nutrients to the system. Each type of plant requires some specific value of pH concentration. So if there is, say, a tomato plant on the top and lettuce plant at lower levels, the difference in pH concentration won't be healthy enough and might change the taste of the plant.

    Hi Don, the thread in case of 3Dponics is defined by three parameters i.e. Pitch, revolution and angle, where pitch = 2.70mm and revolution = 3.6 with a starting angle of 1.54 degree clockwise. Rest, the thread cuts can be trapezoidal, triangular, of semicircular depending upon your design considerations.

    To all participants, please write the descriptions for the system when you upload it. This will be helpful for better understanding your design intent.

    Hi #David & Steve Wegener, being a early stage company, 3DPonics has limited resources. I'm sorry that you did not find this challenge enticing based on the prizes. I can assure you that we will have more challenges with larger prize pools in the near future.

    I would enter this challenge even if there wasn't ANY prizes. We should all use these 3D printers to help. This challenge actually energized my imagination to show my Environmental Science students here the college.... to let them know they can grow food at home.

    Dear participants,

    On behalf of the 3Dprintler, 3Dponics and GrabCAD Community, I would like to thank you for participating in the "The 3D Hydroponics System Challenge".

    Your support and participation in this special event are sincerely appreciated by 3D printing and healthy food growing community, as well as those who serve them. We hope that by this joint effort we can really make and promote the safe and healthy food growing practice to many regions of the world and ensure that the hydroponics would someday be adopted by most of the people around the globe in the future.

    We truly appreciate your support, and look forward for more such contest on this topic from our team.

    Sincerely,
    Atul Mourya,
    Sr. Design Engineer,
    3Dponics.

    Congratulations to the winners! first and second places are very great and cool ideas.
    The third one... I don't understand it... 9 points for usability. Can you explain me what usability means for you? It can be used only with an aquarium....
    By the way,
    I think this is the most inefficient system to take care of red fishes in aquarium....
