3D printing
What is 3D Printing
and how does it
work?
3D printing is an
additive form of
manufacturing
where layers are
built up on top
of each other to
form a 3dimensional
object.
•If you slice a piece of fruit,
each slice represents a
cross sectional layer of the
whole fruit
•If we could create each of
these layers from a
printable material and
fuse them together you
would end up with a full 3
dimensional piece of fruit.
What is 3D Printing
and how does it
work?
A virtual 3D image is
created of an object.
Special software takes this
3d image and digitally
slices it into layers with
specific thicknesses.
Instructions are written in
the form of a language
called a g-code that tells
the printer where to move
and what to do
throughout the print to
form each layer.
The 3D printer then takes
these instructions and
physically forms each
layer. In the end you get a
series of drawing, one on
top of the last together to
create a 3D object.
What are the
different methods for
3D printing?
Extrusion – This method uses material that is, or can be made soft
and malleable and is extruded through a nozzle with a small orifice.
Each layer is built by a bead of material that is left behind as the
printer moves around the instructed area.
Photo polymerization – This method uses liquid resin that is curable
by light. Each layer is built up on the built plate by applying the
resin then using a controlled light system to cure a layer of the
print. The steps are repeated for each layer.
Selective fusion - This method uses granular material that is spread
out on a build plate. The granules are fused together at each layer.
More granular material is before proceeding to the next layer

FAQ
Are your filaments compatible with my printer?
• Filament diameter - The most common sizes are 1.75mm and 3.00mm both of which we
carry. It is recommended using the manufacturers compatible diameter for that specific
model unless otherwise modified.
• Compatible material–The manufacturer of the printer will state which materials are
compatible with their nozzle based on the heat resistance of the nozzle. For build plates
if it is not heated then the recommended material is PLA, (small ABS prints may be done
without a heated bed but adhesion to build plate and warping may occur).
• Spool holder – Different manufacturers have spool holders that hold spools of different
inner diameters. A simple solution is to print a substitute spool holder (which can be
found on STL sharing sites for a variety of printer models) to fit the spool you intend to
use. Otherwise our 1kg spools have an inner diameter of 56mm and our 0.25kg and 0.5kg
spools have an inner diameter of 30mm.
• Regardless of the situation we have a product that will fit almost everyone’s needs.
PLA vs. ABS, why choose one over the other?
• Other than compatibility there may be other reasons to choose one material over the
other.
• PLA is more rigid, can be printed without a heated bed, is biodegradable, is good for
printing finer details and less prone to warping, and can be easily manipulated and bent
with some heat post print for finishing purposes.
• PLA however cannot be finished with acetone like ABS, cooling takes longer and expands
much more than abs when heated so smaller prints may require slower print speeds.
• ABS is more flexible than PLA, it can be welded and smoothed out using acetone, and
prints at similar temperatures to HIPS so can be used in conjunction on dual nozzle
printers and is more temperature resistant.
• ABS however can produce a noticeable odor during printing, is more susceptible to warping
due to shrinkage and may not give as good detail as PLA.
• It really depends on the application but if necessary our technical support team can aid in
determining the best material to use.
What is the diameter variance of your filaments?
• Our filaments are quality control tested for diameter variance.
• Variance for both 1.75mm and 3.00mm is less than ± 0.1mm.
Why is the clear filament more brittle than your other colours
• Because clear filaments have no pigment there is no additional binder to
strengthen the PLA polymers, for this reason it is very common to find clear
filaments to be more brittle.
• In order to maintain the strength of the filaments it is also highly
recommended that they be stored in an air tight container or bag with the
desiccant pack provided when ever it is not in use.
• If ABS filaments are accidently left in open air and become more brittle they
can be revitalized by drying in an oven at a low temperature for a few hours or
left in the container with desiccant for a few days.
Why am I having issues printing when I change to different
coloured filaments?
• Pigments can affect the thermal properties of the plastics, therefore when
different filaments are used print temperatures may need to be adjusted.
• For glow in the dark filaments print temperatures will likely need to be
higher than normal, whereas printing black filaments may require lower
than normal temperatures.
• If there are is warping or adhesion issues when switching colours adjusting
the temperature in 5 degree increments until a good layer is produced
should solve the problem.
