Masked Stereolithography (MSLA)

Masked Stereolithography (MSLA)

MSLA or Masked Stereolithography is the process of curing a photoactivated liquid resin into a hardened shape. MSLA is almost identical to SLA however has an added benefit or producing parts faster.  This process works by curing layers of material on top of each other creating a final product. These parts are isotropic meaning they have the same strength characteristics no matter the printing orientation.

Lead Time

  • Standard 3-5 Days
  • Expedited 1-2 Days

 

Technology Specifications

  • Build volume of up to 330 x 185 x 400 mm (12.99 × 7.28 × 15.74 in).
  • The accuracy for our MSLA printers is +-0.08 mm (+-0.0031 in) on the  X & Y axis, and +-0.05 mm (+-0.0019 in) on the Z axis.
  • The recommended minimum wall thickness is 1.0 mm (0.0393 in).
  • The minimum feature thickness is 0.1 mm (0.0039 in), (depending on feature geometry).
  • Standard layer thickneses are 0.05 mm, 0.1mm, 0.2mm (0.0019 in, 0.0039 in, 0.0787 in).

PLA

About PLA

-This material is stiff and has accurate dimensions when printed. Great for larger models and prototypes.

FLEX

About FLEX

-This material is flexible allowing it not to break under almost any conditions. Great models that you don’t want to break.

ABS

About ABS

-This material is tough which makes it more durable than PLA. Great for functional applications.

Filled

About Filled

-These materials have a metal or wood filler in them. Giving them the appearance of the filler itself.

PETG

About PETG

-This material is similar to ABS however can take even more abuse, however, it loses some stiffness. Great for functional applications.

Specialty

About Specialty

-These materials could be something special you have in mind such as a glow in the dark filament.
