A fab lab (fabrication laboratory) is a small-scale workshop offering (personal) digital fabrication. A fab lab is generally equipped with an array of flexible computer-controlled tools that cover several different length scales and various materials, with the aim to make "almost anything". This includes technology-enabled products generally perceived as limited to mass production.

• It provides teachers with 3 dimensional visual aids
that they can use in their classroom particularly in
illustrating a hard to grasp concept.
• Digital Fabrication make it easy for teachers to seize
the interest of their students compared to just
showing the pictorial representations of objects.
• It enhances hands on learning and learning by doing.
Using this prototyping technology, students will be
able to produce realistic 3 dimensional mini models
• It provides more room for interactive class activities.
How beneficial is Digital fabrication in Architecture Education ?

7 AXIS KUKA ROBOT (KR100 HA L90)
• The 7 axis Robotic Work cell is a large
format 6 axis articulated robotic arm
mounted on a 10 m linear axis.
• The robotic system serves as a flexible,
reconfigurable, motion control platform.
• A variety of tools can be mounted to the
arm, including a high speed router
spindle, miller and an abrasive water jet
cutting nozzle.
• In addition to machining processes, the
arm can be reconfigured to perform
assembly work using a gripper.

8. 8
PHYSICALASPECTS
• The Robotic system is composed of a Kuka KR100 HA L90 arm mounted on a K-1500-3
linear axis.
• The arm has a max reach of 2.8m and a max payload of 90 Kg.
• The linear axis has a 10m travel. This allows the system to move between work cells,
allowing rapid conversion from one task to the next.
• The work cell is pre-configured with a 4'x8' cutting area for multi axis water jet and a 4'x8'
cutting area for multi axis routing.

9. 9
PROCEDURE
• Robotic programming requires additional
steps not found in typical CNC
programming operations.
• There are two
primary methods
used to program this
system.
• One uses the
standard Mastercam
software, using 3-5
axis tool paths.
• This is augmented by a plugin called Robot
master, which converts the tool path to
robotic motion instructions, and simulates
the tool path on a 3d kinematic model.

10. 10
MATERIALS SUPPORTED
• In Water jet applications the robot can cut all
metals and plastics, as well as rubber and wood.
• Milling application, mills the wood and mdf like
materials to produce a desired form.
• In routing applications, The robot is limited to
wood and foam materials.
• In general, robots do not possess the necessary
rigidity to perform heavy cuts compared to a
gantry or bridge type router.
COST
Varies between ₤9500 to ₤10000 depending upon the model used

Abrasive Water Jets
1. Water jet machining is a mechanical energy based
process used to cut machine soft and non-metallic
materials.
2. Involves the use of high velocity water jet to smoothly
cut a work piece.
3. During this process its kinetic energy is converted to
pressure energy.

2. Pump
3. Intensifier
4. Accumulator
5. Control valve
6. Flow regulator

Has an ability to cut intricate design, at high
speed without breakage-
‒ cutting granite, marble, slate, limestone,
soapstone, travertine, engineered stone or
any other material for floors and counters.
‒ porcelain or ceramic tile for inlays or
medallions;
‒ glass and metal for artistic accents and
signage.
APPLICATIONS The Advantages of WJM are:
1. Water jet machining is a relatively
fast process.
2. It prevents the formation of heat
affected zones on the work piece.
3. It automatically cleans the surface of
the work piece.
4. WJM has excellent precision.
Tolerances of the order of ±0.005″
can be obtained.
5. It does not produce any hazardous
gas.
6. It is eco-friendly.
WJM has following disadvantages
which are:
1. Initial investment is high.
2. Requires large space for installation.

The newly renovated Digital Fabrication Lab (FABLab) at Taubman College leverages
state-of-the-art industrial technology to perform architectural fabrication research.
Currently the FABLab houses
• six industrial robots, organized into three cooperative work cells, providing the ability to
work at a wide range of material scales.
• A wide range of large-scale CNC machines
• including two 3-axis routers
• one 5-axis router
• one 3-axis vertical machining center for metals, one 3-axis water jet.
• one 4-axis digital knife cutter.
• Lasers
• 3D printers.
• A CNC industrial knitting machine is a recent addition to the FAB Lab’s suite of digitally
driven tools, enabling complex textile forms to be produced for a wide range of
applications.
