Frequently Asked Questions

Frequently Asked Questions

What glue do I use?

Cyanoacrylate, CA, or plain ol' "Super Glue" will hold resin parts very well. I have not found any plastic solvents that work.

Which paint should I use?

I have yet to find a paint that does not work with UV resin prints! Vallejo Model Color Acrylics are my favorites. They both spray and brush exceptionally well. With Vallejo Acrylics, I frequently skip primer coats, excpet when extra smooth surfaces are required.

What material are prints made from?

As of November 2018, all CG N Scale prints are printed in UV Activated Resin. Read more on UV Resin at Wikipedia: https://en.wikipedia.org/wiki/Photopolymer

Can I sand and cut 3d printed parts?

Yes, but take care! UV Resin can be sanded or filed exceptionally well! Sawing or cutting can be done, but due to the brittle nature of curred UV Resin, cuts can chip and fracture if done too much too fast. Once parts are carefully removed from the support platform, I recommend you break the platform in half in your hands. Continue to break apart one of those halves in your hands in order to get a feel for the material properties. Use the other half of the platform to practice cutting or sawing.

How durable are these 3d prints?

While UV Resin prints are among the strongest "curred" plastic 3D prints, unfortunately these prints are still much more fragile than traditional modeling materials. Careful handling is required, especially on very small detail parts. Once parts are carefully removed from the support platform, I recommend you break the platform in half in your hands. Continue to break apart one of those halves in your hands in order to get a feel for the material properties. Use the other half of the platform to practice cutting or sawing.

Will you make this model in other scales?

Perhaps.
