4.1.
Washing
Parts must be cleaned of uncured resin after printing. Nexa3D recommends washing parts
with xClean or Isoporpyl Alcohol. Washing should be done immediately following printing for
best results.
Wash in a bath using gentle agitation for 5-10 minutes total. Consult local jurisdiction to
determine requirements for safety and disposal in your area.
If parts remain tacky after washing, the solvent may need to be refreshed. Use 2 baths of
progressive cleanliness will help ensure final bath has limited resin contamination. If using
xClean, rinse in water for up to 1 min. In case of 3843-ABS-
Black and xMED412, don’t rinse in
water
–
allow to air dry or rinse in IPA.
Danger:
Most cleaning solvents are
flammable. Don’t use near open flame
and ensure adequate ventilation and spill containment measures are are in
place.
4.2.
Curing
To achieve advertised mechanical properties curing is required in a UV chamber with
>2.5mW/cm
2
of UV light in the 405-365nm spectrum. Duration may need to be extended for
thicker section parts. If warping occurs during cure, then cure attached to buildplate and/or
at room temperature.

Support Removal
Supports may be broken off by hand or with snips, then sanded down to improve finish if
desired. They may be removed before or after washing and curing. Progressivly sanding with
220 and 400 grit paper works well. Mineral oil is recommended for wet sanding and cleaning
excess dust.
