Photo-Bleaching Instructions

Follow these instructions for photobleaching printed models.

•

The fluorescent lamps should be rated 45W, 6500K.

•

When using desk lamps, place the models in a container lined with aluminum foil. Use at least two lamps, more when treating models in a large container.

•

Arrange the models with enough space between them to allow light to reach all sides of each model.

•

Verify that the ambient temperature around the models is approximately 40°C (104°F). Higher temperatures may cause model distortion; lower temperatures may not produce satisfactory results. When using desk lamps, you can achieve the required temperature by positioning the lamps approximately 10 cm (4 in.) above the models.

•

Inspect the models after six hours of treatment.

❒

For parts with a matte finish, this should be enough. Polish and lacquer the parts.

❒

For parts with a glossy finish, continue the photobleaching treatment for up to 18 hours more.

In Stratasys laboratories, there was a tint reduction of approximately 70% within six hours. After 24 hours, tint was reduced by approximately 90%.
