The document discusses 2D and 3D cutters. It explains that 2D cutters can cut materials like thin metals and wood along two dimensions (x and y axes) while 3D cutters can cut along three dimensions (x, y and z axes), allowing for more complex shapes. Both 2D and 3D cutters use a high-powered laser to make precise cuts in materials. The laser is directed based on a digital design created on a computer.

4. 2D and 3D cutters
• A three-dimensional (3D) laser cutter works in a
similar way to a two-dimensional (2D) cutter.
• The main difference is that the 3D cutter can
recognise an object in the x-y-z direction rather
than just x-y
• 3D laser cutters can cut the following materials:
• glass
• crystal
• metal
• polymer
• wood.

5. 2D AND 3D CUTTER
A 2d and 3d cutter is a high powered
laser that cuts material such as thin
metals or woods, used mostly for
industrial purposes.
They make precise and clean cuts, it is
also is very fast which makes it
efficient. It is first designed through a
computer and then sent through a
laser cutter to give you the design.

7. • The machine will cut as accurately as it can
be drawn. This means sophisticated and
complex parts drawn using CAD software can
be produced with ease.

8. 3D LASER CUTTER
• What is a 3d cutter?
• A 3d laser cutter can recognize all sides of a
substrate to make more complex shapes.
A 3d laser cutter can also work with a cube
instead of a flat piece of a material.

9. What is laser cutting and how does it
work?
Laser Cutting.
• Laser cutting is mainly a thermal process in
which a focused laser beam is used to melt
material in a localised area. A co-axial gas jet
is used to eject the molten material and
create a kerf. A continuous cut is produced by
moving the laser beam or workpiece under
CNC control.

12. • An actuator is a component of a
machine that is responsible for
moving and controlling a
mechanism or system, for
example by opening a valve. In
simple terms, it is a "mover".
• An actuator requires a control
signal and a source of energy.

13. What is actuator used for?
• An actuator is a part of a device or
machine that helps it to achieve physical
movements by converting energy, often
electrical, air, or hydraulic, into
mechanical force. Simply put, it is the
component in any machine that enables
movement.

14. What is an actuator example?
• In a mechanical device, an actuator is a
component that turns the control signal
into movement.
• Examples of actuators include: Electric
motors. Solenoids. Hard drive stepper
motors.

15. What are different types of actuators?
• Types of Actuators
• Electric Linear.
• Electric Rotary.
• Fluid Power Linear.
• Fluid Power Rotary.
• Linear Chain Actuators.
• Manual Linear.
• Manual Rotary.
