The panels would be only for aerodynamic and weatherproofing purposes.

      Forming the body out of fiberglass is traditionally the most laborious part of building a custom/kit car, and then the fiberglass needs gelcoat, an awful paint that fades and cracks and looks like a kid's toy from the '50s, and then the fiberglass sags with age on top of all that. And if you damage it you gotta start all over again! And if you're on a small budget you're basically restricted to using the car itself as a mould so that is a real bitch.

      ABS panels are far more durable and if you damage one, you just print a replacement, and the color can be in the material itself - even if you want to paint it, you can make the material the same color to make scratches less visible.

      Also, you don't need an autoclave to do CF work. You can use the fibre and room-temp resin. The problem is that you get too much resin for the amount of fibre. Vacuum bagging helps with this, but the ultimate in weight vs strength is to use the pre-impregnated cloth.

    Additive machining is cute, but not a miracle. It's a slow process. Building up objects one layer at a time takes forever. The consumables are rather expensive. Injection molding and casting are probably 100x cheaper in quantity.

    High-end additive machining system are getting to be quite good. The low-end machines, though, are not yet very useful. The precision is too low, the surface quality is poor, and the material options are too limited. TechShop has both a high-end commercial machine, which is usually busy, and a machine at the MakerBot level, which is almost never used. If you're making tiny parts, you need high precision.

    The big advantage of many of the additive processes is that they don't have work-holding problems. The big limitation of CNC machining is that you have to clamp down the workpiece, and the clamps get in the way of what you're doing. Some part of the workpiece will be inaccessible. So most work requires multiple setups, each of which has to be aligned with the previous setup to 0.001in or better. Designs have to be planned to be clampable.

    The more interesting processes can work metals. But they need 500W to 6KW lasers. If you're going to work in steel, you need enough power to melt steel.

    For comparison, here's a high speed stamping press. This is how most of the small metal parts in the world are made. Once you get the tooling set up, parts come out at machine-gun speeds.

      Additive machining is cute, but not a miracle. It's a slow process.

      Sure, but that's not the point. If you need 100,000 greeblies, you can probably afford to have a $100k mould cut for your high-speed injection moulding process. The exciting property of 3D printers is that it's now possible to create plastic (or metal) parts in small numbers.

      Printing also has some advantages over the usual machining techniques; clamping is one. The absence of tools means you can create structures that are too fragile to achieve with a milling machine. You can print objects inside one another.

      For some industries, the 3D printer is a revolution. I build scale models. Until now, the model kit cottage industry created kits by hand-building a master (a process in which it is basically impossible to get curved surfaces exactly right) and then casting resin copies of it. The 3D printer means that we can create sub-mm accurate masters, or even sell the 3D parts directly (though they still are more expensive than resin cast parts).

      Have to disagree with this comment - 3D printing machines have a number of benefits over CNC milling. From a technical standpoint, 3D printing is not restrained by the limitations of a cutting tool, so you can build 'impossible' geometries including blind holes, complex internal supports and truly amazing: finished assemblies containing moving parts that come out of the printer whole and ready to use. From the business angle the advantages are even greater. With a 3D printer in-house you can shave weeks off of product prototyping cycles - and turn what used to be a slow, tedious, and often manual process into a fast, automated, and highly accurate procedure.
