Desktop Metal says their method for metal 3D-printing is superior to the the laser sintering for volume production of metal parts because of the laser methods slow rate of deposition. DM claims 100 times faster production rates than the laser method. But since this high production rate comes from using many more print heads, it seems to me you could get the faster deposition rate with the laser method by using, say, 100 copies of the lasers. Laser 3D metal printing commonly uses a 200W laser. So to scale this up 100 times would require 20,000W. The cheapest cost I've seen for lasers were by manufacturers in China in the $15 per watt range. So 20,000W would cost in the range of $300,000. Most likely the lasers would be the primary cost for the machines, so call it ca. $600,000 for the full machine able to duplicate the Desktop Metal production rate. One laser 3D metal printing company also suggests use of wirefeed rather than a powder bed can increase the production rate and also reduces the cost of the material: VIDEO: Is Wirefeed the Future of Selective Laser Sintering? James Anderton posted on December 19, 2016 | http://www.engineering.com/AdvancedManufacturing/ArticleID/13955/VIDEO-Is-Wirefeed-the-Future-of-Selective-Laser-Sintering.aspx Near the end of this video they also suggest scaling the laser up to the 15,000W range could bring the production rate to the level of other commonly used metal production methods.

But they do mean for it to be used by engineers in an office setting to do rapid prototyping. Their Desktop Metal Production system due out next year is intended for high volume production. They claim a production rate of 8,200 cm3 per hour, which they say rivals standard manufacturing techniques. As described in their videos, this is for production of multiple copies of a part by a machine with about a cubic foot operating volume: Desktop Metal Production System. https://www.youtube.com/watch?v=aUOCiRktuCo However, it would seem the machine could be adapted to make a single part of this size. That is, instead of making a hundred copies of a part a couple of inches wide by using multiple jets performing identical deposition passes, have these jets be separately, and independently directed to make different portions of one part that is a foot wide. Say, you wanted to make a steel engine within a machine operating volume 3 feet wide on a side. This would require 33 = 27 of the current machines (or a single one scaled up this size.) Say, the engine weighed 270 kilos, that's 270,000 grams. Say the weight is equally distributed among the 27 machines, so 270,000/27 = 10,000 grams for each machine. The density of steel is about 8 gms/cm3. So that's 10,000/8 = 1,250 cm3. This would then take 1,250/8,200 =.15 hours, or 9 minutes to make the complete engine. It's notable in this video the company's chief engineer says their system could be scaled up to make an automobile chassis: VIDEO: How Additive Manufacturing Can Produce Metal Parts en Masse. James Anderton posted on June 06, 2017 | http://www.engineering.com/AdvancedManufacturing/ArticleID/15052/VIDEO-How-Additive-Manufacturing-Can-Produce-Metal-Parts-en-Masse.aspx One imagines also, it could be scaled up to make the complete automobile.

But I was surprised the mass and volume required for the Tesla electric motor is much smaller than a comparable gasoline engine. This video makes a comparison of a Tesla electric motor to a typical gas engine. The power to weight ratio is 10 times better for the Tesla electric motor(!) How does an Electric Car work ? | Tesla Model S. https://www.youtube.com/watch?v=3SAxXUIre28&t=220s The video gives the weight of the Tesla motor as 31.8 kg for 270 kW of power. The size of the motor visually looks like it just might fit within the 14"x14"x14" manufacturing box of the DeskTop Metal's Production machine, though the rotor's central driveshaft might have to be produced at an angle to make use of the full diagonal length of sqrt(3)*14" = 24" inside the box. So instead of needing 27 of the machines I estimated before, we might be able to make it with just a single one: For a 32 kg = 32,000 gm engine say of steel with a density of 8 gm/cm^3, this is 32,000/8 = 4,000 cm^3. At a production rate of about 8,000 cm^3 per hour, the Tesla engine could be produced in about a half-hour by this single machine.

Bumpiness of ride depends on the springs between wheel & body. Greater unsprung mass means poorer following of road uevenness, which degrades grip. It is still sprung by the tyres of course, but not a lot. So the motors get to experience greater lateral forces than they would mounted under the bonnet. Every vehicle design is a mix of advantages & compromises. NT

I think it was based on a design by TRW in the 70's. It is similar to a differential but implemented with sun and planet gearing. One motor/generator balances the torque of the engine, while the other drives the axle in addition to direct torque from the engine. Electrical power flows between the two motor/generators with the battery providing buffering. The gearing is arranged so that at cruising speeds most of the power to the wheels goes through the mechanical path for efficiency and it acts like a parallel hybrid. Under other conditions significant power is transferred electrically and it acts like a serial hybrid. The engine can run at almost any speed independent of road speed so it can be kept at a very efficient part of its RPM/torque curve without any stepped gear changes. If the required power to the road is less than the engine can provide efficiently it can be stopped and the car be powered only by the battery. kevin

Here's a video of showing the operation of a gas engine:
EXACTLY how a car engine works - 3D animation !
https://www.youtube.com/watch?v=FfTX88Sv4I8
It's complex in its construction and operation. It requires high
temperatures and high pressures. Moreover, the multiple pistons moving at
high speed within the cylinders require tight tolerances.
The DC electric engine I linked in the first post in this thread is
significantly simpler. Actually, the Tesla uses an AC electric motor, just a
little more complicated in its construction, but it has an advantage in not
needing permanent magnets.
Another advantage of the electric cars both using DC and AC motors is that
they don't need a multi-gear transmissions. This is also a significant
simplification.
Here's a video describing the electric motor of the Tesla and its single
speed transmission:
How does an Electric Car work ?
https://www.youtube.com/watch?v=3SAxXUIre28
About the copper wire winding, ideally, you would want the entire car to be
3D-printed, but you could have most of the electric motor be 3D printed and
the copper wire windings placed separately.
For the "binder jetting method" of metal 3D-printing, most similar to the
method amateurs use for plastic 3D-printing, it would be difficult to create
also the wire windings at the same time as the electric motor. The reason is
it requires an additional step of heating at high temperature and the wire
insulation would melt. Perhaps there could be used high temperature ceramic
coating for the wires.
Other methods for 3D-metal printing such as electron beam and laser
deposition do not require this extra step of furnace heating so should be
able to do the copper wire winding, assuming the 3D-printer has the
capability of rapidly switching out the material being deposited between
metal and plastic as needed, or perhaps using separate print heads for each
material.
For instance, if you imagine a horizontal slice through the electric motor.
You would have wire insulation, then the copper wire, then insulation, then
copper wire, and this pattern would be repeated, then you would have the
core, then the insulation, copper pattern repeated again. A 3D-printing
method that could rapidly switch between depositing metal and plastic
insulation material should be able to do this.

Bob, go watch your original video. Much about powder spreaders.
