A RESEARCH PROJECT IN DIGITAL FABRICATION AND DISTRIBUTED DESIGN

1. A human-made/hand-knitted vegetal tangible interface by Romain Di Vozzo (France, 2006). An interspecies collaboration : 4 different species : Phytolacca branches, Maple tree, Rosebush pins and a Human.

2. A group of digitally-designed and digitally-fabricated tangible interfaces : Modular, Flexible, Foldable, Circular, Parametric, Press-fit, Flat. Design and Fabrication by Romain Di Vozzo, 2019.

3. SURFACE.IO : Exploring the possibilities and limitations of a digitally-made tangible interface by Romain Di Vozzo.

4. The grey (recycled) leather above was laser-cut and assembled manually.

5. You will design your parts to 3D-Print them at FABLAB UPSACLAY.

6. Let me share with you one of my last experiments in designing and 3D-printing an isometric pattern for flat, flexible and foldable surfaces.

THE DIGITAL-FABRICATION COURSE RULES

1. YOU GO FROM BITS TO ATOMS : YOU TURN CODE INTO PHYSICAL OBJECTS.

2. YOU DESIGN 2D/3D OBJECTS FOR DIGITAL FABRICATION PROCESSES.

3. YOU USE COMPUTER NUMERICAL CONTROL (CNC) : 3D PRINTERS IN THIS CASE.

4. YOU PRACTICE ITERATIVE DESIGN. AND ADVANCED PROTOTYPING. YOU AVOID DESIGN TUNNELS.

5. ALL HANDS ON MACHINES. NO DESIGN-THINKING. YOU MAKE ART.

6. THE VALUES YOU COMMIT TO BY JOINING THIS CLASS : COMMUNITY BUILDING. PEER-TO-PEER LEARNING. THE COMMONS. NO START-UP ETHOS NEEDED.

7. YOUR UNDERSTAND THAT WHAT IS NOT DOCUMENTED ONLINE NEVER EXISTED.

8. YOU DOCUMENT VIA RAW (GIT) VERSION CONTROL OR CMS (WIKIFACTORY).

9. YOU DEMONSTRATE AND CULTIVATE COLLECTIVE INTELLIGENCE.

10. YOU DON’T PRETEND THERE IS NO GLOBAL WARMING/CLIMATE-CHANGE. YOU EMBRACE THE OPPORTUNITY TO ENGAGE AGAINST IT.

11. MORE IMPORTANT : HAVE FUN, EXPLORE, EXPRESS YOURSELF.

3D PRINTING : LIMITATIONS, OPPORTUNITIES AND USEFUL FACTS

1. 3D PRINTERS ARE MOSTLY USED TO PRINT OBJECTS COMPOSED OF VOLUMES AND OVERHANGS. FOR THE MORE COMMOM ONES, THE PRINTING VOLUME IS 20x20x20 MM.

2. USING 3D PRINTERS/ADDITIVE MANUFACTURING TO MAKE THIN PARTS IS UNUSUAL, OR EVEN COUNTER-INTUITIVE FOR MOST PEOPLE. SUBTRACTIVE MACHINERY LIKE LASER-CUTTERS OR VINYLE-CUTTERS AND FLAT STOCKS ARE USUALLY PREFERED.

3. PRINTING VERY THIN LAYERS OF PLASTIC - like 50 microns thick - MOSTLY DOESN’T WORK WELL. THERE IS A MINIMUM HEIGH/NUMBER OF LAYERS TO PRINT TO OBTAIN “CLEAN RESULTS” (MEAN WITH A CLEAN SURFACE AND WITHOUT WARPING).

4. IN OUR CASE, WE WANT TO BE ABLE TO PRINT OUR DESIGNS AS THIN AS POSSIBLE TO KEEP GOOD FLEXIBILITY FOR OUR PROJECTS. BUT PRINTING TOO THIN MEANS SHREDDED PARTS AND UNCONSISTENT ASSEMBLIES. TOO THICK MEANS LACK OF FLEXIBILITY AND MORE MATERIAL INVOLVED.

5. A GOOD MINIMUM EIGH FOR OUR PARTS IS A MINIMUM OF 200 MICRONS. FOR VERY THIN PARTS, IT SEEMS THAT PRINTING THEM IN ONE SINGLE LAYER GIVES BETTER RESULTS. A MAXIMUM LAYER HEIGH COULD BE 550 MICRONS.

6. SO, IF THIS IS TRICKY AND DIFFICULT, WHY ARE WE USING THIS TECHNOLOGY ? BECAUSE ADDITIVE MANUFACTURING ALLOWS FOR COMPLETE CONTROL OF : THE TYPE OF MATERIAL WE WILL PRINT,THE QUANTITY OF MATERIAL WE WILL USE FOR ONE PRINT, THE COST OF THE MATERIAL WE WILL USE FOR ONE PRINT. IT IS MORE SUSTAINABLE, ESPECIALLY BECAUSE WE WILL BE USING A 100% BIODEGRADABLE MATERIAL MADE OUT OF BACTERIAL FERMENTATION.

7. APPARENTLY, WE NEED TO INCREASE BOTH THE EXTRUDER’S AND THE BED’S TEMPERATURE TO MAKE SURE OUR THIN LAYERS STICK TO THE BED PROPERLY DURING THE PRINTING. THESE TRIES WERE MADE WITH 230 C FOR THE EXTRUDER AND 70 C FOR THE BED.

8. FOR A DESIGN OF X = 95 MM, Y = 86 MM AND Z = 0.55 MM, THE PRINT TOOK 6 MINUTES ON A PRUSA I3 MK3S. WITH A 0.8MM NOZZLE. 2.25GRAMS or 760 MM OF PLASTIC WERE MELTED/PRINTED. FOR A COST OF 0.08 EUROS.

9. FOR A DESIGN OF X = 95 MM, Y = 86 MM AND Z = 1.1 MM, THE PRINT TOOK 11 MINUTES ON A PRUSA I3 MK3S. WITH A 0.8MM NOZZLE. 6.34GRAMS or 2130 MM OF PLASTIC WERE MELTED/PRINTED. FOR A COST OF 0.23 EUROS.

MINIMUM AND MAXIMUM THICKNESSES

MINIMUM THICKNESS = 200 MICRONS	x1 LAYER PRINT
MAXIMUM THICKNESS = 550 MICRONS	x1 LAYER PRINT

OTHER THICKNESSES

THICKEST = 1100 MICRONS	x2 LAYERS PRINT
THIN = 150 MICRONS	x2 LAYERS PRINT
THIN = 100 MICRONS	x2 LAYERS PRINT
THINEST = 50 MICRONS	x1 LAYERS PRINT
