FAB LABs
●
●
Started in 2005 in the Center for Bits and Atoms, MIT by Neil
Gershenfeld
Today there is a significant and growing number of FAB LABs around
the world -> at the beginning of 2011, the international Fab Lab
network consisted of over 50 Fab Labs in 16 countries.
-> The real impact of digital communications and computation came in
giving ordinary people control over the information in their lives; digital
fabrication will likewise give individuals control over their physical world
by allowing them to personally program its construction.
Machine list recommendation
Flexible manufacturing equipment within a fab lab can include:
●
●
●
●
●
Laser cutter, plasma cutter, water jet cutter, knife cutter: sheet
material cutting
3-axis CNC machines: 3 or more axes, computer-controlled
subtractive milling or turning machines
Rapid prototyper: typically a "3D printer" of plastic or plaster parts
Printed circuit board milling: 2 dimensional, high precision milling to
create circuit traces in pre-clad copper boards
Microprocessor and digital electronics design, assembly, and test
stations
Origin
●
●
Digital fabrication tools were originally used for prototyping purpose
by the industries. -> NOW the manufacturing machines are used for
end-product manufacturing by small-scale producers and oneperson-factories.
These tiny manufacturers kicked off without or very little external
funding. The main reason for that is low-cost of machines and open
source code and design.
Probably the best known example of the emergence of a personal
technology is that of the personal computer (Lipson and Kurman
Factory@Home). -> The history of personal computers began in the
1970s (Wikipedia).

Industrial revolution
Personal manufacturing “evolution”
Communication Telegraph, telephone, improved
commercial printing technologies
Internet, online shopping, online user communities,
search and rank algorithms that enable users to
find what they’re looking for in the chaos, online
blueprints
Power
Steam, coal, electricity
Powerful computing technologies bring formerly
industrial-scale design and analytical capabilities to
the masses
Machine
technology
Steam engines, coal burning
machines, looms, automated
agricultural technologies.
Factory-scale machines mass
produced standardized objects very
quickly
Personal fabrication machines are ready for home
use, outside the factory.
Cheaper and easier CAD software Hardware and
electronic components get smaller and cheaper
and more powerful
Distribution
Rail ways, improved roads, the
postal system
The Internet becomes the distribution
infrastructure + local Fabbers
Consumers
Emerging consumer markets
eagerly purchased lower-cost mass
produced items
Unskilled labor could assemble
objects on an assembly line
Today’s consumers want to be unique and express
themselves with custom objects
Labor
Unskilled consumers, like unskilled computer users,
can design and operate their own manufacturing
machinery
What about knitting and craft in general?
●
Knitting is very old craft.
●
The origins of knitting go back to 400-500BC

Knitting Machines
The 1st stocking frame knitting machine
Invented by William Lee in 1589.

Circular knitting machine
Hand-powered circular knitting machine of the ChemnitzBased "Strumpfmaschinenfabrik" (Stocking Machine Factory)
for the production of stockings with toes and heels, 1880.

When did a knitting machine appear at home?
The first simple hand-powered flat-bed knitting
Machines were constructed for home use by the
cottage industry in 1890.
As well small-size factories were using these
machines.

Electronic knitting machines
-> although Brother knitting machines have been discontinued, they are still the ones that people have at ho
The two most popular knitting machine lines in the market, namely Brother and Silver Reed/Studio
Electronic/computerized knitting machines
- 200stitches can be used for a
pattern
- has about 600 preprogrammed
patterns in internal memory
- pattern input waus:
mylar paper
INPUT mode (manual)
Floppy drive
The PPD110 and PPD120 allows
you to create your own stitch
pattern designs or to input stitch
patterns from knitting patterns,
magazines or books, using a TV as
your screen, and then to transfer
your stitch patterns to your
knitting machine. Stitch = pixel
=> knitting machine is a 1st personal manufacturing
tool at home

Nintendo Knitting Machine (1987)
Source: http://www.ign.com/articles/2012/08/31/nintendo-almost-made-a-knitting-add-on-for-nes
The ad says:
●
“You're looking at the Nintendo Knitting Machine. It's not a
game; not a toy; not something a young girl can outgrow
in three or six months or even a year. It's a machine that
interacts with the powerful Nintendo Entertainment System
to actually knit sweaters: and not just one or two patterns
but a multitude of different and unique designs. The
Nintendo Knitting Machine is just one more example of the
innovative thinking that keeps Nintendo on the cutting
edge of video technology. And your customers on the edge
of their seats. Of course we should probably mention that
no other video game system offers anything even remotely
similar. But why needle the competition?”

Decline of knitting
●
●
●
In 1980s knitting suddenly became unpopular because of
appearance of machines, and cheap and available clothing
However with the boom of Internet in late 1990s knitting
communities appeared again. Internet enabled sharing, learning, and
communication.
Among the first Internet knitting phenomena was the popular
KnitList with thousands of members. In 1998, the first online knitting
magazine, KnitNet, began publishing. Blogging later added fuel to
the development of an international knitting community.
Thanx Internet!
●
Guardian: But despite this decade-long reign over the lifestyle pages,
the last 12 months have been particularly good for knitting. Peter
Fitzgerald, a retail director at Google UK, says that while online
searches for knitting-related terms have grown steadily since 2004,
the growth this year has been really noticeable. "Our data shows
that searches for knitting have increased over 150% just this year,"
he says. The term "knitting for beginners" has increased by 250%.

Conclusions
●
●
●
●
Knitting machine is the 1st digital personal manufacturing tool at
home, which has been totally over looked nowadays in the age of
digital fabrication.
Textile fabrication has a huge tradition and importance in society ->
available skills & knowledge.
Open knitting has a great potential in the growing field of digital
fabrication -> cheap, available and recyclable material, growing
community of fabbers/innovators/makers, new business
opportunities, and more.
The fabrication and business model is changing (disappearing bigsize industries, FAB LABs, startups, factories at home). Hence,
knitting and textile manufacturing introduce new possibilities and
personalization.
Thank you for listening!
