I don't do any of the resin casting, that's done by talented people who are good at it, and have been doing it for years. I create some custom parts like wheels, tires, alternative front ends (to change my '74 Dodge Monaco to a '77 Dodge Monaco Royal) and get them 3D printed. I use ProEngineer software because I use it at work all the time, then upload the 3D files to somewhere like Shapeways or iMaterialise and they send me a master model.
This gets used as the master model for the silicone mold
I've had several master models printed for resin casting, as said above just make sure the resolution (number of triangles the stl file is saved as) is high enough and you specify a high-detail material for printing.
I've had wheel inserts done, tires and complete bodyshells
Here's the idea
And here's the reality, all parts done from 3D masters, including the wheels and tires for the pickup
For the 3D files I either bought it or created it myself, then uploaded it and did the usual route for silicon mold and resin casts. The tires are urethane, what doesn't come across in the photos is the tread pattern and sidewall letters I could do!
I had to redesign the front suspension because the tires were fouling on the wheelarches. I moved the kingpins out so they pivot within the tire's footprint, now they don't swing around so far when the truck steers.
Graphics drawn up and made
And it all fits together!

Me too, which is why I made these to be stronger. With all the track time my cars have had, the kids racing them and they were used all day non stop at an exhibition I've never had one break. The body post came loose on the van once but that's because I used the wrong glue, once it had been fixed it's been fine. And you don't want to know how many takes it took making those videos... The A Team video had the van jumping 20 times at least!
Were they really used as taxis? I remember seeing them like that on TV, but they were used everywhere on TV at the time! There must have been a fabrication shop in Hollywood making a dozen roll cages per week
Thanks! My car (the Tonka and the real one) were replicas from The Love Bug. The blue stripe is a little lighter than later cars, the VW badge on the hood is blanked off and the running boards were body coloured too. How did I miss that on the Tonka toy?!
The 1:1 also has the wide wheels from the racing scenes and slightly lower suspension too.
