Introduction to digital prototyping tech
This module presents state-of-the-art technology for 3D design and printing and gives some links to other sources, where one can find more information in this fields. AUTHOR OF THE MODULE: Stavroula Sokoli

New Artisans
This module focuses on implementation of the 3D design and printing in present artisans work. The field of artisanship is very vast and it is not possible to analyse (as well as make a list) all the jobs that can be defined as "artisans". We have chosen for this module the most characteristic fields then. After recalling the most important information regarding 3D modelling and printing, we present in details, how 3D technology changes jewellery-making process. We give also some hints regarding implementation of this innovation in other handicraft works, like those using leather, wood, metal, glass and ceramics as raw materials. The artisan production is closely connected with other sectors, and we have to consider that the development of 3D modelling allows a greater integration of these fields with undeniable benefits in all sectors. For this reason, the field of architecture and interior design in which artisan production is a strategic factor has been also considered as an example.

Youth creativity in the digital age
The aim of Module III is to present one of the possibilities, how the Module I and Module II can be implemented in small makerspace for and with young people interested in different implementations of 3D modeling and printing techniques. On the basis of workshops run in our 3D laboratory in Wadowice, we prepared practical lessons on how to introduce this interesting subject to your students or lab members. Following the lessons you will get information on how to start teaching 3D design and printing and what steps you can take in order to encourage people to create their own models. We are presenting here examples of specific activities on several different subjects and requiring specific skills going beyond 3D design. Finally we are giving here some tips on evaluating the process and showing potential advantages of learning 3D techniques for entrepreneurship possibilities. AUTHOR OF THE MODULE: Łukasz Putyra

2. 3D design software – Introduction

3D printable models may be created with:
(a) a computer-aided design (CAD) package, via
(b) a 3D scanner, or by
(c) a plain digital camera and photogrammetry software.

3D printed models created with CAD result in reduced errors and can be corrected before printing, allowing verification in the design of the object before it is printed.

As shown in the diagram below, a file may need to be translated to an accepted format for 3D printing. This may involve taking out extra data, modifying the file format, and slicing (layering) the data. Software programs such as Blender, an open source 3D creation suite, will accept and translate many file formats.

The same article, “Introduction to 3D Printing: History, Processes, and Market Growth”, offers, also, a table that presents a list of some of the 3D print file formats in use:

*.STL	Stereolithography; 3D single color (one extruder ~1980s)
*.WRL	Vermal; multi-color (supports more than one extruder)
*.OBJ	Open source 3D geometric format
*.X3G	MakerBot format
*.PLY	Scanner output
*.3MF	3D manufacturing format - 3MF Consortium specification (introduced in 2015, and still in use)

Table 2.1. Some 3D Print file formats

There are numerous CAD programs available – some are freeware, some cost quite a bit of money. Of course, they all have their pros and cons. Here is a list of some of the most common accessible to educational/youth establishments:

– Blender
– Sketchup
– TinkerCAD
– FreeCAD
