White resin 3D printing process

Womp uses SLA (Stereolithography) technology for 3D printing, offering unmatched detail and smooth finishes. Here’s how it works:

How it works

Stereolithography (SLA) creates 3D objects by curing liquid resin with a laser, layer by layer. A computer-guided laser traces each layer's shape onto the resin's surface, causing it to solidify. The platform rises after each layer, allowing the next to form. After printing, the object is cleaned and UV-cured for strength.

Understanding Drain Holes

Drain holes are important in SLA (Stereolithography) printing because they allow trapped liquid resin to drain out of hollow or enclosed parts of the printed object

Problems without drain holes

  • Incomplete Curing: Trapped resin inside the object doesn’t get fully exposed to the curing light, so it remains liquid
  • Pressure Build-Up: During post-processing (like rinsing and curing), trapped resin can create pressure, which may deform or even crack the object.
  • Inefficient Cleaning: Drain holes make it easier to fully rinse the object after printing, ensuring any uncured resin is removed and leaving only the solid parts.

Womp Solution

  • Easily add drain holes anywhere on your model
  • X-ray view to easily indentify hollowed pockets

If you choose not to add any drain hole, however, the 3D printing technicians may need to place one themselves to ensure the resin drains properly. This helps create a durable, fully cured model, even if it means adjusting the original design slightly.

WPP specifications

Properties

  • High resolution (25-100 microns)
  • Smooth surface finish
  • Excellent detail reproduction
  • Good dimensional accuracy
  • Suitable for functional prototypes
  • Can be sanded, painted, and finished for end-use parts

Color and Finish

The color of Accura White resin can vary slightly and may change over time. It can range from bright white to a soft off-white or light yellow tone.

UV exposure may cause subtle yellowing over time. For best color stability, keep your print out of direct sunlight or consider additional protective coatings.

Post-Processing options

  • Basic finishing: Sanding, polishing, or tumbling for a smoother finish
  • Coating options:
  • Decorative finishes: Dip coating, flocking, spray painting, airbrushing, or traditional brush painting
  • Advanced treatments: Acid or vapor smoothing, Plating, chroming, or water transfer printing (hydrographics)

Each method can improve your print's appearance and durability. Keep in mind that some methods require special care and expertise.

Safety Considerations

WPP is not food safe without additional treatment. It's also not bio-compatible or skin safe for prolonged contact without protective coating or paint.

For food-related or skin-contact applications, additional treatments or coatings are necessary to ensure safety.
