Congratulations!
You have just purchased a new type of 3D printer
using Daylight Polymer Printing (DPP) technology.
This is a patent applied-for method of image creation
that hardens liquid with the normal visible light emit-
ted from an LCD screen. This revolutionary system is
a new method of Additive Manufacturing that uses the
same intensity and part of the spectrum that we use to
see. This is the energy providing source that initiates
the free radical or cationic polymerisation necessary
to change the liquid photopolymer resin into your har-
dened object. The light emitted from the screen is not
modified and the images are safe for viewing.
These are some of the advantages of DPP technology:
i) Low cost- We use high resolution low cost LCD
screens that are widely available in monitors, ta-
blets, mobile phones and televisions. These pro-
vide phenomenal value for money, which we pass
onto you.
ii) Reliable- Because we don’t modify the back light
the screens are used normally and have a long life
expectancy.
iiI) Very large scale- The screen lights every pixel
,
t
light projector which in turn exposes every voxel,
so you can create large areas of custom product
simultaneously. As the format grows this makes it
much more efficient than all alternative means.
iv) Very low energy usage- It uses the amount of elec-
tricity to run a tablet, this is an order of magnitude
lower than that required to operate a laser or a di-
gital light projector.
v) Low adhesion at the build interface- the heat crea-
ted by the screen is very low and the small amount
of initiation energy in the polymrisation creates very
little attraction to the vat film.
vi) Limited over-exposure- Using this low intensity vi-
sible light, the energy is dissipated very quickly, it
either strikes a photoinitiator and creates a free ra-
dical or it loses all the energy hitting solid material,
so there is very limited ability to over-expose and
create solid parts where you don’t want them.
