Chocosketch, 3d chocolate printer by Rokit

Last month we got the chance to visit the headquarters of Rokit in Seoul South Korea. Thanks to Shane we got to know more about the and their 3d chocolate printer, Chocosketch.

During our visit we got the chance to see the printer in action, taste its prints and get an overview of the features.

Printing Chocolate




The Chocosketch is the chocolate Desktop 3d printer from Rokit. Rokit is a South Korean 3d printing company with printers that range from desktop to professional.



The build up volume for the printer is 210 x 120 x 70 mm, and the overall dimensions are 454 x 300 x 500 mm. It has a clear door locked with magnets for easy access to the interior.



The printer works with syringes filled with Chocolate. Rokit provides 3 types of chocolate that has been tested. Those are white, milk and dark. You can use your own material although you would need to tweak the configuration parameters to make sure it works properly.



The printer has a preheat station in the inner left side of the printer, where cartridges can be preheated while printing.

This is especially good if you plan to print multiple or big items that might require more than one syringe of chocolate.


Printing plate

The build plate is made out of stainless steel, what makes it pretty easy to wipe out. Although It is fixed, so don’t expect to pop it into the dishwasher. Pro tip: for that use some cooking or wax paper, pro tip use some oil to stick it to the plate.



3d chocolate prints are possible by controlling the temperature. For that the the Chocosketch has a fan that forces air circulation. There is no active cooling system . Proper air circulation makes sure the chocolate sets and the nozzle does not get clogged.


The printer has a removable top for easy access to the extruder, to load and unload the syringes.


The extruder itself works similarly to the RichRap syringe extruder, where a belt pushes down the plunger. Obviously it includes a heating system that keeps all the syringe warm including the nozzle.



There is 3d different ways to send files to the printer. Using WIFI, USB or SD-Card.

Price and contact

The printer retails for about 2100$(depending on the country) and each preloaded syringe for about 5$.

For more information make sure to contact with Rokit.

Thanks Rokit and specially Shane for letting us visit and get a closer view of the printer.

Walkthrough Pinya3, 3d food printing platform

In this video we go through some of the reasons why we build Pinya3 a 3d food printing platform.

Pinya3 is the open source 3d food platform that we use to create our digital recipes.

This video was made during our time in Seoul. Thank you to the Art center Nabi for allowing us using their kitchen, where we did this walk though pinya3.

Pinya 3 was design to fit in the kitchen. The most important feature one was the dimensions. Fits perfectly under the cabinets of the Pier9 kitchen. Also the distant between towers was designed to easily slide in and out dishes. Also having a usb connector and a power plug, was an improvement from previous printers to be able to survive in the kitchen and to be easier to move around.

All the electronics are located in the upper side of the frame to avoid the electronics getting damaged by spills or food explosions that may happen during the kitchen wars.

The printer uses magnetic ball joints to remove and clean easily its parts. Also it makes easier to change the tool used.

Pinya3 is a 3d food printing platform because it can use many different tools, not just one.

The base is made out of stainless steel 304, with a thickness of 3mm. The rest of the frontal plates are to hold connectors, the LCD screen and to hide cables. This helps to give a more friendly appearance to the printer for when it needs to relate to people.

On the upper part we have the electronics. Pinya3 uses an Smoothieboard. It has a basic setup with the board with 5 stepper drivers plus 2 external ones. Also we decided to add the LCD screen to test how the interface will play in the kitchen and the interaction with people.

Also since it is Pinya3 it has 3 pineapples etched in the plywood parts.

We hope you enjoy this short explanation. If you have more doubts do not hesitate to contact with us!

3DC Instructables Roundup pt 1

In this 3 part series we’ll be sharing some of Luis’ 3D food printing experiments that were posted on Instructables as part of his Artist in Residency at Autodesk Pier 9.  All are about 3D food printing and to be shared and used to hopefully get people involved in 3DFP.  What good is 3D printed food if it can’t be shared? So here we go…

Heated Nozzle

Working with heated nozzles and 3DFP is something that presents a challenge.  Many things to think about and lots of different variables come into play when working with heat and food printing.  This isn’t your Momma’s food extruder (although if your mom is printing food with heated extruders then that is really, really awesome!).  The Instructable is unique in that Luis broke down his process for machining the tool and it’s worth a read if you’re thinking about working with heat and 3DFP but even more since you’ll likely have to build your own tool for this as well.

Lucky Hummus Experience

You probably remember something similar to the Lucky Hummus Experience from a while back on 3DC. This Instructable is unique because Luis explains some intimate thoughts: 

Building 3d food printers is one thing. Using them another. Engaging people to understand, relate and experience them a completely different one.

This is the goal of this first 3d food printing experience for Pinya3. Trigger people imagination and start a dialogue around 3d food printing.

He breaks down the steps to take to have your own lucky hummus experience, to include reminding us to NEVER FORGET TO SIEVE!!!  (While at Pier 9 I did my best to master a sieving technique and it is much harder than it sounds) If you want to create your own shapes like the lucky four leaf clover then feel free to use the Roses App here on the site on the 3d food printing design tools page.

Testing food for 3D food printing


One of the most fun aspects of 3DFP is playing with the food!  To make it sound more official and a tad professional then we call it “testing”…..  Actually that’s just me.  In all seriousness, we as a community of 3DFPr’s won’t be able to advance the technology unless we keep testing and documenting how different foods function with 3D food printing; if they even work, how they react, viscocity, does the taste change, etc.. etc..

That is the thought behind the Instructables: Testing food for 3D food printing, to share how different foods are working with 3DFP.

The foods Luis worked with in this Instructable:

  • Lucerne Cream Cheese with Chive & Onions
  • Posh Bagel Cream Cheese
  • Artichoke Spinach Hummus
  • Water and Xanthan Gum
  • Jelll-O
  • Greek Yogurt

Stay Tuned...

As mentioned this will be a 3 part series so come back again soon and subscribe to our mailing list below as well so we can let you know when we make some breakthroughs or need some feedback from you on our projects.

“Eat me if you Dare” – Food Grade Paste Extruder from VormVrij

If you’re not familiar with VormVrij then get ready.. They’ve created some great products for 3D printing with clay and now have a food grade paste extruder available for your next 3DFP themed event or school!

It really is a thing of beauty; you can clearly see the craftsmanship and care that went into its creation.

VormVrij Food Grade Paste Extruder

Here are some notes from VormVrij about the LUTUM Food Grade Paste Extruder:

  • made of bronze
  • motor, auger and housing can be disassembled in one twist
  • improved extruding speed
  • exchangeable augers
  • optional barrel cap offers continuous flow mode

We were so excited about this news that I reached out to Yao van den Heerik (founder of VormVrij) to get more personal about their new food grade paste extruder.  The following is a portion of our conversation and following the Q&A check out the video of the LUTUM 3D printer and food grade extruder in action.

Hi Yao – How in the world did you decide to start printing with food?

We started printing with marzipan last year (pictures below) for the desserts of the Christmas family dinner, but at that time we did not develop the motorized extruder yet. So we left the food printing for the time being and focused on developing the extruder for printing clay.

As our clay extruder is now functioning to a level exceeding our own expectations we wanted to try food again. (Christmas is coming again!)

What led you to decide to create a food extruder?

The fact we already produce 3Dprinted ceramic tableware makes food printing a natural follow up to explore and contribute to a richer culinary experience, definitely a direction we will explore more with in the near future!  Here are the first results: https://plus.google.com/+YaovandenHeerik/posts/bRqz6f14TPv

VormVrij paste types

Where there any challenges in the development of the extruder?

The two things we changed to our ceramics 3dprinter were the air valve to regulate the speed at which the pastes reach the extruder and the material the extruder is made from. Normally we print clay, and that stuff is much more difficult to extrude than the food pastes. I guess it’s due to the water content. In clay you want as little water as possible, totally different to food (except marzipan). In essence our printer was over dimensioned for these soft pastes and I guess that’s why it was so easy to adjust the system to print food.

We also had to upgrade the material of the extruder. Most 3Dprinted metals are slightly porous and therefore difficult to clean and easily contaminated by pathogens. Our normal extruder is made from 3Dprinted stainless steel, the extruder we use to experiment with food is 3dprinted in wax and then casted in raw bronze. Hard enough to last but easy to scrub or boil clean (the extruder can be taken apart or assembled in less than a minute).

Now that you’ve had a “taste” of 3DFP what is next for you and VormVrij?

After the ‘I amsterdam’ print we decided that printing food would be a perfect addition to our current work.  We are now developing a food grade variant of our printer. But as you mentioned this is much more difficult and has many restrictions in terms of material use, safety and clean-ability. This reflects drastically in the cost of the printer but on the other hand that new machine will be industrial grade and safe for restaurants or other public venues.

Currently Yao and VormVrij are looking for investors to propel the development of a large scale food grade 3D printer.  You can find out more about the team at VormVrij on their website VormVrij.nl

We want thank Yao for allowing us this interview and wish him and his team all the best with their new venture into the world of 3D food printing!
