SAFETY
GUIDELINES
- 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 ventilated
room.
- We recommend connecting Magna to your
extraction unit through the hole in the back
panel, using the supplied extraction spigot
- Resins are classified as irritants, not harmful,
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.
Please note that the latest instructions will always
be available from:
www.photocentricgroup.com/3d-support

document for future reference. Follow all warnings
and instructions marked on the product.
- Magna weighs approx 100kg. Ensure you have
four people available to remove Magna from its
crate.
- The footprint of Magna is 850mmx640mm. Take
care to choose a flat and stable work bench
that can handle Magna’s weight and foot print.

3. CLEAN
1. Take off the platform. Drain off excess resin by
holding the platform vertically over the vat.
2. Wipe off the remaining excess resin from the
platform with absorbent paper.
3.1. Place the platform in Photocentric Wash99
filled with Photocentric Resin Cleaner. Wash for
5-10 minutes.
If necessary, leave longer than 10 minutes.
Take the platform out of the wash unit and rinse
with warm/hot water.
Or
3.2. Spray warm soapy water over the parts. A
sponge or soft brush can be useful to clean
detailed parts. Rinse with warm/hot water.
1413

4. Once cleaned, there should be no trace of
uncured resin visible.
5. If you have access to an air compressor with an
air gun, you can dry your parts after cleaning.
We recommend this for delicate and accurate
parts to ensure all holes and pores are free of
any traces of uncured resin.
1. Gently remove the parts from the platform
by sliding the scraper (provided) or a snap-
off blade knife (taking great care) underneath
parts.
2. Place parts under hot water (60°C) in UV light
for 15 minutes to remove the surface tack.
3. Large parts can be post exposed for 1 hr in
water, under UV light.
4. Once post exposure is complete, dry parts and
your print is ready.
5. To prepare for the next print job, scrape off any
cured resin and clean the build platform with
hot water and Photocentric Resin Cleaner in
the spray bottle. Dry the platform and place on
the print arm.
4. FINISH
Note: Take extra care to make sure the platform
is clean and there is no residue of cured parts.
Any hard resin may pierce the vat film and could
cause print failure. Please see Maintain Section
5.
6. Pour the remaining resin from the vat back
into the bottle using the funnel and filter paper
provided.
7. Use the vat cleaning tool (provided) to direct
any excess resin from the vat down towards
the funnel.
8. Place the vat on the Foam Vat Cleaning Mat
(provided) and mop up any resin residue with
absorbent paper.
9. Use the soft spatula (provided) extremely
carefully to remove small cured pieces.
Note: Take extra care to make sure the Cleaning
Mat is perfectly clean and there are no chips of
cured resin on it. If the vat film gets damaged,
it can lead to a vat leak and damage to your
printer.
10. Make sure your screen plate area is clean prior
to placing the vat back into place on the printer.
11. If you have evidence of a leak on the screen,
mop up the liquid resin immediately using
absorbent paper or a damp tissue with IPA.
Hardened resin can be removed by chipping
off carefully with the provided soft spatula. It is
extremely important to keep your screen plate
surface clean from any resin. If not, you risk
print and/or printer failures.
