Pinya3 is an open 3d food printer platform design to fit in the kitchen and work with as many different types of food and mixtures extruders as possible.

Requirements:

  • Portable
  • Height under 50cm (~20")
  • Compatible with existing food compatible extruders
  • Open platform

Step 1: Frame Design

The printer configuration is based on a delta robot. Because it allows to have a fix printing platform, meaning that the food that is being printed does not move. The second reason is because this configuration permits easy access and disassembling moving parts (specially important for cleaning operation). But I can not fool anyone, the true reason is that I love how they move.

The desired printable area must have the diameter of a regular dish. But what does that really means? I am not sure so I head to the kitchen to measure different plates sizes.

ID (inner diameter) ranges from 1.6 to 9 inches (4-23 cm), OD (outer diameter) varies from 4 to 11 inches (10-28cm). The inner diameter corresponds to the flat surface on a dish, where we want to print. And the outer diameter is the opening size that the printer must have fit the plate inside.

The last one is going to set the dimensions for our printer because we want to be able to fit dishes easily into it! Knowing that the distance between delta towers must be at least 11 inches, we can abuse this awesome delta calculator to get a rough idea on the printer dimensions. If you feel like doing some kinematic calculation go ahead. I did this in the past, and turn out the building process is way more important to have a nice accuracy. Still food is about deliciousness not precision (yet).

Printer height is limited by the distance in Pier 9 kitchen between the counter and the cabinet around 50cm (20").

<p>Hi there,</p><p>i would like to know if you have printed anything else with it?</p><p>what other ingredients can i print with it and what is it depends on?</p><p>what are the limitations?</p><p>thank you</p>
<p>Hi!</p><p>Thanks for your comment, I have another instructables with other types of foods that I tried. </p><p><a href="https://www.instructables.com/id/Testing-Food-for-3d-Food-Printing/">https://www.instructables.com/id/Testing-Food-for-...</a><br>Also you can read more at http://www.3dgitalcooks.com of other experiments I did in the past :) Have a nice day,</p>
<p>May i ask about your instructablse journey? i see you join recently in jan last year, I am curious in how your passion lead you from Barcelona to SF Pier9 !! i am from Hong Kong and am applying for the coming summer internship, i am dying to pump out my 3d idea with the awesome CNC!! !! May i ask about the international presence too?</p>

<p>How would you print something say like Chocolate? Or would the materials used for printing have to be semi-solid but squeeze-able through the extruder - and not temperature dependent?</p>
<p>Chocolate is tricky, also depends a lot on the type of chocolate. Controlling temperature is a necessary. But depends on what you want to achieve, I would look into other people printing chocolate and learn from them. That's the best way :)</p><p>Thank you</p>
<p>What would you change to make this a FDM 3D Printer, for use with filament?</p>
I would add a plastic extruder a heated bed. I would also add autoleveling, and I would had make it bigger. For me, I would had taken a different approach, but definetely could work.<br>Thank you
<p>Wow, That is awesome!</p>
<p>Thanks a lot for your words :)</p>
<p>Well, there is a 3d food printer that can do the same, but a lot faster and a lot cheaper.</p>
<p>I think beating the human hand motion is a tough one, specially if you add our amazing closed loop vision system! I would argue though about repeatability and the cheaper factor. I think this are too different approaches. For me one cool thing about 3dfood printing is that allow to more people getting involved designed for food, without having to be masters at piping or decoration. But I agree that there is different ways to do the same :) Thank you </p>
You said nothing about what this uses for ingredients. Is it some sort of synthetic slurry, powder, or ??
<p>After a cursory search for &quot;3d food material&quot; I found this-</p><p><a href="http://www.3ders.org/articles/20150218-3d-printed-colored-hummus-mixes-additive-manufacturing-with-gastronomy.html" rel="nofollow">http://www.3ders.org/articles/20150218-3d-printed-...</a><br><br>It's hummus paste. Seems that anything thick enough to not drip out of the extruder could be used, icing, flour and water mixtures, blended peas, refried beans, jello, jelly. But that's just my opinion, I haven't made any 3d printed foot at this time.</p>
<p>Hi! My belief is that anything can be printed if you have the right approach. That being said, liquids, pastes and powders are the common materials. The extruder needs to fit the food/mix properties. Hummus is by far one of the easiest ones to have fun with, easy to tweak and play with! Thank you.</p>
<p>Hi sorry, for the test I was using Jell-o, just because its easy to source and print with. Hopefully more test prints to come soon. Thank you</p>
Very nice project
Thank you!
<p>Thats a really nice delta printer. How much did it cost in the end?</p>
<p>Hi!Thanks for you comment. The project budget was around 600$</p>
<p>Thanks for the Instructable with all details and design files. I feel like it got within reach to reproduce the printer. I especially like the magnetic joints.</p><p>By the way, investigating the potato milling challenge, not that machine. The slowest spindle speed is 10k RPM. Would make a mess.</p><p>I think that using a DC motor in slow speeds would remove "material" nicely though. But then any Prusa Mendel framework could be used to hold the slow speed spindle.</p>
<p>We are sooooooooo gonna test the potato milling challenge. I love the idea of low spindle speed, maybe an stepper motor would do the trick instead. Also I have been thinking about using different Tempura postprocessing deep frying techniques to grow on top of the milling designs. We shall see were all this mess ends.... hahaha</p>
Wow. Very nice, very nice. Love the picture of you standing on the mechanism :))
Thanks a lot. Its good to try things first hand :)
