I went with real this time.


In Topic: Those that have done resin casting; what is your favorite casting resin?

Hands down, Smooth On. Used it for years. Tried others, not the same. Also, there's a distributor in Orlando.


In Topic: Have you ever noticed ?

In Topic: Air bubbles in Alumilite resin

22 March 2014 - 10:01 AM

I have held off answering this until I tested this answer myself. I had just visited my local Smooth On distributer at the time this question was asked. While there, I asked why the Smooth Cast resin that advertises no bubbles, was coming out with bubbles big time. He explained it to me thusly. Pour parts A and B into your separate containers. Instead of mixing them right away, let them sit for 5 to 10 minutes to gas out. Remove any visable bubble and combine slowly into the mixing container. stir gently as to not creat any new bubbles. Pour into mold gently. My results, perfect casting with no bubbles.      


In Topic: 3D printing growing as we speak

22 February 2014 - 06:26 AM

There will be leaps and bounds in the developement of decktop 3d printers over the next  few short years. DLP printers started showing up in the open source community over the last couple years and also, the B 9 creator printer was introduced. These have incredible detail, but rather small printing footprint. DLP hasn't really taken off and I believe that many were waiting for the patents to expire on some of the laser printers. These patents started expiring this month. Marlin, which is one of the open source firmware that runs the ramps electronics for FFF printers, just announced that they have incorperated the ability to print with a laser with the firmware. Once the open source community starts developing laser technology, thing will really develope. For those that don'tknow, it was the open source community that developed the FFF or FDM printer. Makerbot came out of the reprap project. These printers that people post on this forum are only someones design of the same printer with maybe some improvement, but that is what it's all about. Taking something and improving it. The reason these printers, FFF & FDM are coming down in price is because:1-The electronics are about 1/3 the cost they were a year ago 2- the design is cheaper to build 3- Better technolgy is developed. Using the vcr analogy, the cheap printers are the vcr, the DLP printer is the cd and the laser printer, just over the horizon, is the dvd.
