Ho scale M of W Power container gen.

Q:

A:  Pending test print 03/22/2019

 

 

What is the difference between the old PLA based models and the new resin based models?

   Our new Photon, resin based printers give our new models a new and improved finish. Unlike our older models that had a ruff finish these models have a nice flat smooth finish. " It dose NOT have that 3D printed look to the finish".  We have also added new details or redesigned many of our models.

Here is an example of the difference in finish on the Phantom Ballast regulator. 

  

 


 

Painted models?

Q: Some of the models I have purchase came painted or had a coat of primer on them while others where not painted. Whets up with that?

A: We normally ship models in unpainted condition. Some times we pull a random model and give it a quick coat of paint as a quality test. A painted model shows the details better. Then the model is put into inventory if it passes the visual quality test.

 


 

 

What kind of resin?

    UV Resin Specifications

  • Model Number: 405 nm resin
  • Material: resin monomer , photoinitiator
  • Hardness: 79 D
  • Viscosity: 552 mpa.s
  • Curing wavelength: 405nm
  • Shrinkage: 7.1%
  • Tensile strength: 23.4 Mpa
  • Curing time: 6-10 S
  • Elongation at break: 14.2 %

    Note: Resin color may vary. 


 

Sticky parts?

  While we do our best to wash the models/parts before we ship them, some resin residue may appear on the models/parts. Some models may even ooze/seep some uncured   resin. If this happens try to wash the model/part in 95% isopropyl alcohol (IPA). If the part dose not come clean, use the contact form and send us a photo of the part and we will replace it at no charge.   


 

How dose Phantom Hobbies wash or clean the models / parts after they where printed.

We wash them in a bath of 95% isopropyl alcohol (IPA) or equivalent in a ultrasonic cleaning chamber. They are then rinsed in water before going to the UV curing chamber.


 

Resin curing

UV curing is a process in which ultraviolet light and visible light is used to initiate a photochemical reaction that generates a crosslinked network of polymers.[1] UV Curing is adaptable to printing, coating, decorating, stereolithography and assembling of a variety of products and materials owing to some of its key attributes, it is: a low temperature process, a high speed process, and a solventless process—cure is by polymerization rather than by evaporation

Note:  You should put a thin coat of primer paint on your models as soon as you get them. Unprimered / unpainted models / parts that are exposed to a light source like the sun or other sources that may contain UV light may cause the models / parts to cure farther. This could cause the model to become fragile or even crumble.
