All Frequently Asked Question:

Do your resins cure with LEDs or Diode Lasers

Yes, our resins have been tested to work with a range of Lasers and LEDs, up to 405nm wavelength. We also have an alternate test photoinitiator at 450nm on demand.

Does your resin detach from non-stick surfaces?

Yes, we have resins that are tested against PDMS (Polydimethylsiloxane-divinyl) silicone. it may also be used on fluorinated films such as FEP and Teflon.

I have problems with the object detaching from the build base, what can I do?

The build base needs to adhere sufficiently to the object so that the first layers of the print attach to it solidly and don’t fall off at any point of the print. Below we list different strategies that have been tested to this effect:

• Perforated metal build areas are very effective at fastening the initial layer in place and guaranteeing dimensional stability (by reducing warping of the initial layers)
• Brushed Aluminum (sometimes powder coated) is often used as a material for build tables, but the resins tend to detach from it. These bases should be pre-coated of resin, hardened under the sunlight or UV light. This will produce very good results.
• Layering spray glue (3M or similar brands) before a build has been tryed with mixed results.
• Some resins will attach to PVC so covering the build base with vynil film is an option.

Why do I need to provide a telephone number to place an order?

Product shipping will be carried out by a courier service and these, overwhelmingly, require us to provide a contact telephone number to call to in case there are problems finding the shipping address or to reschedule a delivery if an initial try has failed.

We do not resell or forward any of the information you have provided to third parties. All provided information will only be used to fulfill the order.

Why are your products listed by weight and not by volume.

The reason is that the weight of the products is an invariant figure specific to every resin. Not so the volume, which is dependent on temperature. The specific density of our resins oscillates around 1 to 1.1 g/ml depending on the product.

Which dyes or pigment colors are best for your resins?

This depends on your printer setup, desired resolution and irradiance power per surface area. Dyes and pigments that absorb UV and blue light are the most effective at controlling cure depth and as such, resolution: yellow, orange, red and black are the most effective. Pigments are more effective absorbers than dyes.

 

Is it better to use dyes or pigments?

Dyes dissolve completely in the resins and don’t need to be re-homogenized before every use. They are transparent but also absorb light less efficiently.

Pigments are more effective light absorbers than dyes but as these are made of solid, undissolved particles, they need to be resuspended from time to time as they will eventually precipitate. Pigmented resins are opaque.
