8.0 Supplementary Information
poor print results but damage Robox® - we can’t take responsibility for poor
quality filament causing damage to the product.
• Where can I find mechanical, chemical and safety specifications (MSDS) for
the print materials?
These will be available alongside each Robox material on our website –
www.cel-robox.com/materials.
• What is the life expectancy (hours) of the printer?
Robox is currently undergoing rigorous life-cycle testing and from initial
results, it looks like 2000 hours of printing is possible before any maintenance
is required.
• Can you explain the resolution metrics (feature size, layer thickness, X/Y
resolution etc.)?
Feature Size – this refers to the smallest feature that can be realistically
produced in the X+Y dimension (parallel to the bed), and is dependent on
nozzle size – for Robox® the minimum feature size is 0.3mm (300 microns).
Minimum Layer Thickness – this is the thinnest layer that can be extruded
by Robox®, and has the greatest impact on surface finish. Robox® can print
with 20 micron layers, producing an almost completely smooth outside
perimeter.
Resolution – this specifies the theoretical maximum resolution, i.e. the
smallest motion that can be performed by the motors and the linear
components. For example if a step motor rotates 1.8° per step, and the
controller can produce 16 microsteps that equates to ((360/1.8)*16)=3200
steps per revolution. If this motor is connected to a screw with a pitch of
0.5mm (as is found on our Z axis), this equates to (0.5/3200)=0.15625 microns
per microstep or 2.5 microns per whole step - see section 2.2 for more
information.
• Is Robox® compatible with all AC supplies?
Robox® includes a 230/110V internal switching power supply, and will
include the appropriate mains lead for your country.
