I’m not sure if this has been posted but wanted to give a tip on how to get optically clear parts. We are making microfluidics devices in our labs and for fun wanted to see if there was a cheap and simple way to polish the parts.
Our polishing steps are:
Wet sand in order with 800, 1000, 1500, 2000
Does not have very long, and alternate the direction each time you change paper.
Next use Brasso metal polish and PEC-Pads, or any low lint soft cloth. Use little circles.
Rinse
Next use toothpaste with the same technique as the Brasso.
You can finish it off with Novus #1 to clean and protect.
Alternatively, you can use the Novus polish system and achieve similar effects.
Out of interest, what grit system are you working with there?
In the past I’ve used toothpaste then Brasso - from dim & distant memory I was under the impression the toothpaste grit size was larger than Brasso’s abrasive.
I really ought to try flame polishing a print to see how it works.
These are purely suggestions and if there is a better product that is great to know, both suggestions were cheap, and I learned from a person who makes professional models. It’s nice to learn about alternatives.
I have tested the method out and works great, and I have strict requirements since I’m working in a research field. I tried using just using toothpaste and the result with using the Brasso first was far better.
Give it a try and test it out and report back your results.
Remember to use the little circle technique I mentioned. Like buffing your car.
