Both the Mold Star and Smooth Cast are bubble free or close to it. The trick to using the Smooth Cast is to pour parts A & B into separate containers, let them sit for a few minutes to clear any bubbles. Then gently combine the two and gingerly stir so as to not create any new bubbles and pour. The pressure pot, I have found, forces resin into all tiny areas and gives a nicer cast.
It's been a year since I posted the first prints off of my high def 3d printer I build. Since that time, I have been able to do some amazing things with it. These spark plugs are an example. In the first pic are three scales. The largest is 1:8th or larger. The ones on the left are 1:16th. The ones on the right are 1:24th/25th. The ones in these two pics are the 1:16th & 1:24th/25th.
I have been using Smooth On for about 14 years and wouldn't use any thing else. Here is an Olds engine that I cast about a month ago. I cast 1:25 inside door hardware and they come out beautifully. Currently I am molding with their Mold Star 30 and casting with their Smooth Cast 310. I use a pressure pot at about 40-42 psi.
I'm with Rich on this as far as the only model car site I visit. My computer is in the same room as my modeling desk, so I tend to spend more time than I really need to on the computer. As a retiree, I find that I have a lot of time on my hands and that managing that can get out of hand. I should really should spend more time on projects, but I have found that the concentration wanes with age. Maybe I should take up learning to spell properly. My college prof's in the past and this web site tell me i'm wrong. O"well, hard to teach an old dog new tricks.
Thank you Eric, you've made my day. What I'm about to say is meant to be taken in a positive, kindly way and not harsh or negative . My post was not intentionally directed at you. From your opening post on, you never presented this 3d print to be anything other than what it is. My concern was that it seemed that others were seeing what they wanted to see and not reality. I was excited to see that someone had bought a 3d printer to use for model car parts printing. One of the major reasons for my w.i.p. 3d printing posts is to encourage others to get involved. Otherwise, I would just complete the model as some others have and say-here it is, I 3d printed this at home. The experience you gain from working with your printer will carry thru into future, more advanced printing machines. Now, as to your print. Take note on the 35 LaSalle post, I state, at least I think I did, that to get the best print with a filament printer, you need to break the file down into pieces. Teach yourself the best orientation of the part on the build platform. Learn when and where to use support material. You will see a steady improvement in your prints. Good luck, happy 3d printing.
