M70 High Precision Resin Instruction
The Product Description
M70 resin is a high-precision rigid resin that comes salmon color. It contains unique inorganic fillers allowing for low shrinkage, wear resistance, matte and delicate surface, so it has become a favorite with action figures, BJD and garage kit (GK) printers. The ability to create parts at very high resolutions makes these materials ideal for applications like miniatures, precision parts and high detailed mold.

Printing
Before printing: make sure that the build plate is fully leveled. Because M70
is a high-precision resin, the transmission depth is lower than other resins,
so it is easy to have the prints not stick to the build plate. The build plate
needs to be leveled so that each position is exactly one piece of A4 paper
away from the LCD screen.
(Please use 4 sheets of A4 paper for leveling in strict accordance with the
method in the picture below)
Listed below are some cases where prints are dropped due to issues with the
build plate, and solutions:
a. There is a depression in the middle of the build plate, which needs to be
polished according to the method shown in the figure below.
(This situation generally occurs on printers with a print size of not less
than 8.9 inches, many of their build surfaces are uneven)
b. Use a magnetic build plate. The magnetic plate is too smooth to stick to
the prints and needs to be removed or use 800 grit sandpaper to roughen the
magnetic platform before use
c. Due to inertial positioning after the knobs or screws of the build plate
are locked, as shown in Fig3. Correction with spacers when mounting the build
plate
After eliminating the above problems, you can start setting parameters and
slicing. We recommend using the “Rest time after bottom retract” Setting, set
8-10S. It is more conducive to the bottom layer sticking to the build
platform.
Supports Settings: Sets the medium supports. Note that M70 resin is difficult
to stick to the build plate, you can set a thick bottom raft or increase the
number of bottom layers to ensure that the bottom layer of the prints can
stick to the plate.
Printing Settings: You can download the resin printing parameters from
RESIONE’s official website. The detailed operations are as follows: RESIONE’s

Cleaning and Post-curing
Cleaning: You can use ethanol(concentration ≥95%), or IPA to clean, the
cleaning and soaking time shall not exceed 10min. It is recommended to use a
toothbrush to scrub the prints. After cleaning, blow dry the print with
compressed air.
(Why does M70 resin need to be cleaned with a toothbrush? Because some
printers have an anti-aliasing effect, it is easy to produce a layer of
incompletely cured resin on the surface of the print, which makes it difficult
to clean and easily cause the surface of the M70 print to become white. )
Post-curing: After cleaning and drying, the print can not be cured
immediately, which will make the surface of the print white. It is recommended
to place it for half an hour after drying with compressed air and wait for the
solvent on the surface of the model to evaporate before post-curing .If you
use a post-curing box with a power of 40W, our recommended post-curing time is
about 10mins (Adjust the post-curing time according to the power of the post-
curing box, the relater the power, the shorter the time). 
Attentions:
a. Too long post-curing time will make the resin prints easy to warping, hard
and brittle.
b. The resin prints will be fragile after post-curing. It is not recommended
to apply force to the prints immediately. Just need to wait for a while until
the internal stress of the prints is completely released.
