# Paste 3d Printing Pottery Lab


![](https://i.imgur.com/J4HXOZL.jpg)

Additive manufacturing (AM) techniques are mainly deployed through layer-by-layer or contour crafting by using FDM technology using standard thermoplastics such as PLA/ABS/etc. Nowadays there is a global collective drift towards the development of alternative natural or biobased materials that can be 3d printed.

This workshop will examine the implications of paste extrusion, in the 3d printing process and how it modifies the traditional printing methodologies. Needing to adapt kinematic movements to its characteristics.
This intensive workshop will focus on the techniques involved in paste 3d printing from creating bio- 3d printable materials together with traditional ones such as clay or ceramics with a custom opensource 3d printer paste extruder PDM (paste deposition modelling).

Paste materials can be printed with a custom opensource modification kit . Making this materiality 3d printing reaches a level of precision which is very close to that of plastic polymers extruders thanks to the combination of a screw extruder and a pressure extruder. With this technology, it is possible to accurately control the flow of material and also use retraction to interrupt deposition. Innovations also include a system which could be easily adapted to most of the standard 3d FDM printers in the market, making it easy to replicate everywhere in the world.

### Short version
This workshop will focus on paste extrusion in 3d printing and how it modifies the traditional 3d printing methodologies. We will focus on the techniques involved in paste 3d printing from creating bio-based 3d printable materials together with traditional ones such as clay or ceramics with an custom opensource 3d printer paste extruder PDM (paste deposition modelling). Nowadays there is a global collective drift towards the development of alternative natural or biobased materials that can be 3d printed.

# FAB BLIMP

![](https://i.imgur.com/QnkYo78.jpg)
![](https://i.imgur.com/GKLU1yh.jpg)

Blimps are relatively simple flying machines; they use a gas that is lighter than air, such as helium, in order to be able to float, while using motored propellers on a bottom structure to move forwards and backwards. By building your own blimp bag out of plastic bags, filling it with helium, and attaching it to a motorized bottom, you can construct your own relatively inexpensive indoor blimp.

### Workshop Structure
During the workshop the participants will develop different skills related to digital manufacturing.
- Design, cut and weld blimp bags to forms the different volumes that will then be filled with helium
- Prototyping a structure light enough to hold motors and electronics, and capable of directing both right and left as well as up and down the blimp.
- Design and program an app to control the blimp

![](https://i.imgur.com/rnitenR.jpg)

Open discussion on how maker education can be used for entrepreneurial skills & social innovation.

An interactive discussion group on Maker Education and how to use it to increase entrepreneurial skills in children and youth around the topic of social innovation, based on the DOIT project of which FabLab Barcelona and Waag/Fablab Amsterdam are part.

### Workshop Structure

* Fab Lab Barcelona will share learnings from the pilot programmes in schools and makerspaces of the DOIT project. Some maker activity where attendees actively participate and reflect on how open source technologies, maker education practices and open design can be used by local communities to address local problems.
* After that we will have an interactive discussion on how to use design thinking in Maker Education for Social Innovation. 
* Also we would like to see what the current need in the maker network is for training materials for facilitators of Maker Education. 


# HYPERCONNECTED TOOLS FOR DISTANCE LEARNING

![](https://i.imgur.com/uqrRpfw.jpg)
![](https://i.imgur.com/YVHP5cI.jpg)

Hands-on interconnected activity. We will experience some of the tools, techniques and methodologies used during Fabacademy and MDEF this year at Fab Lab Barcelona, in a practical and decentralized way. With the aim of establishing connections and dialogues of those ahh and ohh moments.

Not only do the participants to watch their designs come to life, but they also will learn how to produce custom files and gcode scripts to run multiple outputs; how to fix the machine remotely by fixing the firmware online and collaborative management of use times by using issues on the GitLab repository.

# DESIGNING LEARNING ECOSYSTEMS IN AN EMERGENT FUTURE

![](https://i.imgur.com/8T7UL8y.png)

Theoretical workshop to introduce our framework to design learning ecosystems based on a multiscale approach within innovation labs. We will discuss about toolkits, methodologies, communities and facilities.
It creates a hyperconnected learning ecosystem that provides feedback whilst navigating between home, Fab Labs and educational institutions. The framework reflects how it is possible to learn almost anything in a lab, school or at home, whilst building skills and key competencies to meet social challenges in an uncertain future in the SDG's context.
