3D Printing
3D Printer
A machine that creates three-dimensional objects from a digital file.
3D Model
A digital representation of a three-dimensional object.
Electricity
a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current
Power Supply
where or how the power gets to the circuit
to conduct
vodit
Filament
The material used in 3D printing, often plastic or metal.
Layer Height
The thickness of each layer in a 3D printed object.
Eletrical Current
2 types of electrical signals
DC = direct current
flow between power and ground is constant
AC = alternating current
The current flow constantly reversing ( 50Hz )
It has to do with how the electricity is generated
Switches
Parts that close the circuit in order to activate the device
E.g.: ON/OFF
Selectors which decide what part of the circuit is active
(which way the current flows)
insulator
izolant
Extruder
The part of the 3D printer that heats and melts the filament.
Nozzle
The part of the extruder that dispenses the melted filament.
Conductors
a type of material that conducts elctricity (copper, brass, aluminium, steel, tin,...)
Transformers
some of the oldest and most common parts, used to alter the voltage and current
wire
drát
Slicing
The process of dividing a 3D model into layers that the 3D printer can understand.
Infill
The internal structure of a 3D printed object, used to provide strength and support.
Semiconductors
Materials that conduct electricity under specific conditions (compounds)
Motors
Devices that turn electrical energy into mechanical energy - ‘basically power to movement‘
solder
pájka
Additive Manufacturing
The process of creating objects by adding layers of material.
Subtractive Manufacturing
The process of creating objects by removing material from a larger block.
Electric Circuit
path for transmitting electric current
Relays
relay = electrically operated switch
Use: when necessary to control a circuit through a low power signal
electromechanical (moving parts) vs solid-state relays (using semiconductor properties)
E.g.: door lock in a car, safety relays
torque
točivý moment
