- Keep the printer and resins out of the reach of
children.

- The resin is an irritant to skin and eyes. Always
wear gloves when coming into contact with
the liquid resin. Always use in a well ventialed
room.

but in exceptional circumstances people can
be sensitive to the resin and develop a skin
irritation or rash. Avoid this possibility by always
wearing gloves and avoid breathing fumes.

- The printer should be operated on a stable
and level surface, preferably away from direct
ambient light.

CONGRATULATIONS

You have just purchased a new and innovative Direct UV-Light Printing (DUP) technology
based 3D printer. The direct UV method of printing uses LCD display panel as a matrix of
pixels that hardens the liquid in the resin vat with the light from the UV light source. UV-

LEDs at the bottom is used as background lighting.

Bulld Plate

Resin

Resin Vat

Light beam
UV LED

This revolutionary system is a new way of printing that uses normal UV light as the energy
source to provide initiation of free radicals polymerization that is necessary to change the
liquid imagepac resin into your solid hardened object.

LCD Panel/
Display

Working Principles of
DUP 3D Printers

There are two amazing advantages of DUP technology:

1. High resolution can be achieved through affordable and accessible LCD screens.
These screens are the same as the widely available screens of mobile phones and
tablets, so phenomenal value for money is passed directly on to you.

2. Energy used by GR1 is an order of magnitude lower
than comparable systems. This is not only good news for your energy bills and
the environment, but also performance advantage due to avoiding unnecessary
creation of excess energy that leads to over-curing. The problem of over-curing
is common among Digital Light Projector (DLP) and laser systems.

POST PROCESSING

Place the platform to WANHAO Washer. Remove the objects by sliding the
scraper in at their base. Wash off any liquid polymer in alcohol container. You can

gently clean it with a soft brush or sponge, take care not to damage it, it will not

achieve full hardness until after post exposing in UV light. A WANHAO Washer
will clean your objects without the possibility of damaging them.

Alcohol

Check your object is thoroughly clean as resin cannot be easily removed afterwards and

then leave it under water in sunlight for about 3 days. Or in the WANHAO CURING
BOX for 20 minutes. The longer you leave it under water the darker the colour will get,

some colour change is inevitable. When it is completely post-exposed it will be strong

and have a dry surface. Empty the contents of the vat back into the bottle by pouring
through a sieve with the vat on a at surface wipe the inside thoroughly
with absorbent paper. Replace the lm when damaged.
