PRESENTATION OF THE I3 METAL MOTION
The latest creation of the eMotion Tech company, the I3 Metal Motion
promises stability and accuracy.
With all our knowledge and experience acquired with our previous
printers, we wanted to propose an elegant and reliable solution
to the problems encountered on many 3D printers on the market.
The I3 Metal Motion will seek to become a symbol of durability and
robustness, a precision tool at your disposal.
The I3 Metal Motion is, rst of all, a solid steel frame that makes it easy
to build in compare to any classic I3, with a low number of components.
We have searched to develop a heavy and solid structure, including
reinforcements in order to minimize vibrations and maximize the stability.
A sharper and reliable extrusion
The whole extrusion system is mounted on a steel carriage that
avoids the distortions that most of the plastic parts are victims. For
a higher ergonomics and quality, we have brought our solutions :
- a disengageable extruder to take o󰀨 or engage the lament with a
simple ngers pressure.
- Manual extrusion of the lament made by a molded wheel to have a
very sharp ow.
- No clearances or empty space on the path of the lament, so it’s
possible to print with every kind of lament available on the market
(PLA, ABS, G-l, G-Carbon, eMotion Flex...)
Here are the features of the I3 Metal Motion :
• Dimensions : Height 440mm, Width 400mm, Depth 430mm
• Print volume : 200x200x200mm
• Thickness of the layers : from 100 to 350 microns
• Compatible laments : 1.75mm diameter, PLA, ABS, G-Fil, M-Fil, Flex
• Heating bed : yes, up to 110 ° C.
• Rated print speed : > 80mm / s
• Maximum movement speed : 200mm / s
• Nominal movement speed : 150mm / s
• Average accuracy (X, Y) : 100 microns
• Average accuracy (Z) : 50 microns
• Electronics type : eMotronic and TF card
• Microcontroller : LPC1768, 32-bit ARM Cortex-M3 at 100MHz
• Print with Hexagon 1.75mm extrusion head (interchangeable nozzles)
• Nozzle outlet : Ø 0.4 mm by default (modiable a posteriori)
• Operating System : Win XP, Vista, 7, 8, 10, Ubuntu 12+, Mac OS X
• USB connectivity
• Interfacing : LCD screen with TF card reader
• Power supply : 24 Volts / 320 Watts
The kit includes :
All the spare parts of the kit
A spool of 500 grams of PLA

SAFETY INSTRUCTIONS
General safety instructions
The nozzle can reach 270°C, do not touch the nozzle while the printer is
working.
A supervisor is needed when the printer is used with young people.
KEEP PRINTER AWAY FROM CHILDREN AND ANIMALS
Operate in a ventilated room. Plastic vapors e󰀨ets are not known. In
case of use in a closed room, we recommend the use of an extractor fan.
The addition of protections is your own responsibility. Safety can be
improved by :
• Housing protection
• Smoke detector
Electrical safety
The power supply provided is labelled CE. The power supply is protected
against short-circuit and do not need any modication. The I3 Metal
Motion operate at 24V and is not concerned by the low voltage directives.
Further informations
Informations above are not exhaustive.
We used sources of informations that we consider reliable. However, we
cannot guarantee that all these informations are true and complete.
We assume no liability for loses, injuries or damages due to assembly,
transporting, storage or removal of the product.
NEVER LEAVE THE PRINTER WORKING WITHOUT
SUPERVISOR.
