The ITK-20121 exhibition and conference

The ITK-20121 exhibition and conference were held at the hotel Cumulus Resort Aulanko in Hämeenlinna on 1-3 December 2021. The ITK Conference is a unique event for digital education and learning in the education sector.

Lecturers Oona Haapakorpi and Jouko Matedoja from Omnia and Heli Kalluinen from RASEKO presented the results of the Digi2go project.

The  purpose of this project was to create, develop and build a  new industrial3D-food printer with start-up company Mehta Heino Industries Oy.  Our aim was to experiment and develop a 3D food printer using MHI3D printer software. Idea was that we built the printer collaboration with students and working life. And we seem to have succeeded this well.

In the presentation of the ITK event, we said the following:

The process of 3D printing consists of a few essential tools. First you need to have a 3D model and a 3D printer, but there is an instrumental piece in between. The 3D printing slicing software essentially acts as an intermediary between the 3D model and the printer.

The 3D printing cutter prepares the selected model for your 3D printer and generates G code, which is a widely used numerical control (NC) programming language. In this presentation we introduced Simplify 3D activities, because it works in a Manu 3D food printer.

The world of ”3D Chocolate Printing” (Digi2go project)

The aim of the project is to create and develop new 3D chocolate printer.

At the same time we going to create material for new degree called  ”3D technology in catering services, 20 competence points”.  The following competencies are required of the student in that degree:

  • Students familiarise themselves with orders and use a 3D printer.
  • Students describe the techniques of 3D printing with chocolate or sugar.
  • Students use a 3D device and print a product.
  • Students assess their own competence.

At the same time, the project also aims to develop a 360 ° ThingLing environment by creating a pilot version for Kokkikilla’s website.Idea is create unique experiences with interactive images, videos…The aim is to promote the use of open learning materials by utilizing virtual environments.


Chocolate 3D printing has been around for some time but it still belongs to a very niche part of the 3D printing world. That doesn’t stop it from advancing chocolatiers’ horizons, though. 3D chocolate printing is similar to 3D plastic printing, which itself is based on traditional coordinate system technology.

Normal chocolate figures are made by pouring melted chocolate into different molds and allowing them to cool to a solid. This really limits the shapes that can be achieved. However, with a Chocolate 3D printer, we can print some pretty crazy chocolate shapes, which would not be possible with a traditional mold.

Toinen Digi2Go hanketapaaminen

Digi2go-hankkeen tavoitteena on luoda ja kehittää 3D‐ suklaan teknologiaosaamista samalla tehdä uusi tutkinnonosa 3D-tekniikan hyödyntäminen ravitsemispalveluissa, 20 osp.

Hankeessa tehdään yhteistyötä Mehta Heino oy kanssa. Yrityksen ensimmäinen tuote, oli MHI3D-tulostin, joka on 3D-tulostin. MHI3D-tulostimen käytön oppiminen vie vain muutaman minuutin, ja se säästää koneen käyttäjien aikaa ja vaivaa .

3D-suklaan printerissä tulemme käyttämään samaa pohjaa mutta muunamme koneen käyttötarpeen 3D-suklaan tulostuksen tarpeita varten.
