Velleman projects K8200 Short user manual - Handbuch (Seite 3)

The 3D printer contains a lot of moving parts, but the force of the stepper motors is too low to cause serious injuries. Never-
theless it is recommended to provide additional protection against mechanical risks.
The easiest way to make your 3D printer “accident proof” is to put it inside a protective enclosure which completely covers
the 3D printer – with or without an access door and fume extraction. (numerous designs can be found on the internet)
To make it extra safe a switch which interrupts the power supply of the printer when the enclosure or door is opened can be
added. It is also advisable to install an external emergency stop switch, which also cuts off the power supply.
Providing adequate protection is the responsibility of the assembler.
Always cut power before maintenance or modification.
Mechanical safety and protection:
!
The 3D printer is not intended for use by persons (including children) with reduced physical, or mental capabilities,
or lack of experience and knowledge, unless they have been given supervision or instruction concerning the use of
the appliance by a person responsible for their safety
Children should be supervised to ensure that they do not play with the appliance.
The above information is believed to be correct but does not purport to be all inclusive and shall be used only as a guide.
The information in this document was obtained from sources which we believe are reliable.
However, the information is provided without any warranty, express or implied, regarding its correctness.
The conditions or methods used for assembling, handing, storage, use or disposal of the device are beyond our control and

for loss, injuries, damage, or expense arising out of or in any way connected with the assembly, handling, storage, use or
disposal of the product.
General safety information:
There is a potential risk of burns as the Printer head (extruder) can reach up to 270°C.
The use of common sense should be sufficient to prevent burns, but in some environments it is highly recommended to
provide additional protection. (see § Mechanical safety and protection)
The max. temperature of the heated bed is 60°C, this is below the 1 min. burn threshold for plastic surfaces according to
CENELEC Guide 29. Normal reflexes prevent long contact periods with hot surfaces
Always let the 3D printer cool down for 60 min. before maintenance or modification.
Risk of burns:
!
This printer is designed for use with PLA and ABS filament (MSDS for the Velleman filament is available).
PLA: is a safe and non-toxic material, there are no known health safety risks when used in 3D printers.
ABS: when printing with ABS there is a distinctive ‘burned plastic’ smell. This is quite normal but it may also cause head-
aches, respiratory- and eye irritation with sensitive people (although it is not toxic)
Only use the printer in a well-ventilated area, if printing with ABS it is advisable to add a fume hood (with active car-
bon filtering for ductless extraction). Fume extraction is mandatory for use in offices, classrooms and alike.
Never burn printer filament, toxic gasses and vapors will be generated if exposed to fire.
