#55344, "RE: 3D Printing"
In response to In response to 8


          

Odd this thread is brought forward because I've just finished printing the castings,frames & cylinders for the port reciprocating engine. I plan to finish and detail it but not sure how detailed it will go. I don't have much free time these days so it will take a long time to finish.
Here's what I have. It's about 11-1/4"L x about 7"H:


It's a variant of a model made for my engine room project. Here is the starboard engine with some port side elements mixed in:


All of it will be (almost) exclusively 3D printed.
I think 3D printing is a mystery to most folks. Most people I've talked with believe the printed parts are similar to injected molded parts and all of the shaping/artwork is produced within the 3D software and printing process. Once printed, it is ready for the model.

It is not.
Printing is only the first step.

There is quite a lot to do post-printing. The surface is not smooth like injection molding. The printing process involves stacking layers upon layers of material on top of each other which crates a rough uneven surface full of valleys and hills. Creating a surface which is suitable for the model you're making is where the real art begins. I work with PLA which is resistant to glue and paint and it creates a challenge of its own. The only glue I've found which works well is the 24hr JB Weld epoxy, for example.
I love to air brush acrylic. Acrylic doesn't stick to this very well so I follow it up with a water-based clear polyurethane. The polyurethane is glossy which shows all the imperfections on the surface. More of a challenge.

I've been doing 3D modeling for almost 2 decades mainly with a program called LightWave 3D by Newtek. It's in the same category as 3Ds Max, Bryce, Maya etc. I've learned what I do in LW3D very well and that's the main reason why I stick with it.

If I were a 3D noob wondering where to start then without question I'd download the free open source Blender 3D (https://www.blender.org/) and YouTube for the seemingly endless tutorials ranging from the very simple noob basic instructions up to and beyond the most advanced processes. Blender is NOT a half-bit tossed together crappy freeware. It's a very seriously capable, and expandable modeling program which most anyone can learn if they have a serious mind to do so.

Blender is multi-OS supported so you can load it on your Windows, Mac or Linux machines.
Me? I'm not a MS Windows person. I HATE windows but my LW3D only runs in the Windows OS. My main OS is Linux OpenSuse and LW3D won't license in that environment. I'm an old fuddy-duddy who is too much set in my ways else I'd definitely be using Blender.

I was wondering.... Does anyone know the mathematical formula to determine the scale of an object?
Thanks.
