Project Information

I have a friend who is a member of the SWAT team for the Salt Lake City Police Department. I thought I would surprise him with this.

I bought the model from CGTrader, but it was meant to 3D print and was hollowed. After I sliced it using Netfabb, I had to bring it into ZBrush to fill all the hollow areas. I then brought the repaired slices back into Netfabb where I grouped the different slices so when I imported them into Aspire I could do the double side cuts at one go.

I cut it using MDF, but after all the glue up I sprayed the bronze metal coating. Because the rifle would have been to fragile using the MDF, I 3D printed that.

Hope you like it.

pretty nice figure but I didn't see any mention of the table saw work nor scroll saw, nor hand saw, router but then things are changing regarding wood working technology

Netfabb is a software that I got to manipulate 3D 'STL' files. ZBrush is a Clay Sculping software, similar to doing it with real clay except it's on the computer. Rhino is a 3D Cad/Cam software. Aspire is a modeling software, but is also where I create toolpathes for the CNC machine.

When I retired, I went from working 80-plus hours a week at my business, to doing nothing after I sold the company. I don't have anymore hair to pull out of my head from being bored so I took up 3D graphics and the CNC machine, plus any other fun equipment in my shop. For many years I've enjoyed it and don't plan on giving it up anytime soon.

Watch for more of my projects.

I was very impressed with your elephant you did posted a little while ago ( https://www.lumberjocks.com/projects/418087 ). This SWAT member appears to be even more complex and it really does look like a bronze casting.

Actually applying the metal powder is fairly simple and once you do it, you'll find a lot of projects to apply it on.
First you need a few inexpensive tools:

1: Spray gun with a 2.3mm nozzle for a little over $40 on places like Amazon or Ebay. Not the same one at Harbor Freight which is only 1.6mm. (Titan Gravity Feed HVLP Spray Gun 2.3mm nozzle)

2. A digital scale that measure grams ( about $10 on Amazon).

3. Plastic container to clean gun. You need about a cup Acetone to clean the gun. Completely disassemble and clean each part immediately after you have sprayed the resin to avoid it setting in the gun. Takes about 5-minutes to clean the gun, it takes about 10-minutes when the resin starts hardening.

I get the metal powder and resin from https://www.metalpowdersusa.com although he doesn't list the resin on his website, you can call or email him from his website. The resin is a lot thinner than fiberglass resin you get at Home Depot or an auto parts store. The thinner resin when mixed with the metal sprays better. The mixing ratio 3 grams of metal to 1 gram of resin & .3 grams of MEKP hardner (i.e. 100 gram metal to 34 gram resin) . Make sure you paint the the model with Primer before applying the metal mixture.

I use a board with nails sticking out to suspend the model while spraying, sitting on some cardboard. Use Steel wool and a light gage wire and nylon brushes to sand off the surface resin after it has set for several hours. You may also apply some patina to highlight parts. If you sand through, mix up a little in a plastic cup and touch up with a flux brush.

Although Aspire has a slicing feature, it's not always applicable, so I use Rhino, Netfabb and ZBrush to manipulate the models, however, there should be a lot of free software that will work. I found the software that runs my 3-D Printer also has a slicing feature.

Wow, you really are an advanced level computer-woodworker.
Wish I had a fraction of those skills.
Well done. Congrats.

really nice. can you put something of real size to be able to understand the scale.

I also don't understand the tools or methods…. but I see your talents…. Nice job, as was the elephant… I enjoy seeing your projects…
