Do we have enough surplus energy for this manufacturing proposed?

The energy requirement looks to be the heating of the source material and then the cooling of the fiber. So to produce the amounts at the rates being discussed by MIS, it should not take much power in a % value of that available on ISS or even on a more power constrained BA330 module. These are small NAROO (no assembly required on orbit) rack mount boxes that are doing the work not some large built up system. To produce from 6 to 14 km of fiber a 2 kg block of source material is what is being brought to a melting point. It takes ~20Mj to melt the 2 kg block and that is equivelent to just ~6 kwh. Meaning to also cool it would require 12kwh to produce the entire fiber from the source block. If the unit only pulls 200w it would take ~60hours (2 1/2 days) to produce the complete fiber.

So the amount of power used by these boxes is almost trivial to the other power requirements of the ISS or other space-station such as a BA330.

A BTW that 6km of fiber at $300/m let alone the $3000/m price is worth $1.8M. At $3,000/m it is worth $18M.

http://www.spacedaily.com/m/reports/UK_Ministry_Of_Defence_increases_investment_in_Magna_Parva_in_space_manufacturing_technology_999.html

Current pre-manufactured structures (antennae, solar arrays, deployment booms) designed to go into space are high in mass and volume, and have specific launch environment requirements. By manufacturing in space, many of these requirements are eliminated, offering an order of magnitude capability increase over current state of the art systems. Based on a deployed length to packed volume ratio of greater than 1000:1, the Magna Parva market disruptive technology can offer a new and unexplored utility from even small satellites.

New related story that suggests that to support expanded in-space manufacturing the down-mass capabilities (to get the manufactured goods to the largest market) will need to expand greatly.

Made In Space has built what it calls a “miniature fiber-pulling machine” that’s about the size of a microwave oven, which will be flown to the International Space Station (ISS) later this summer on SpaceX’s Dragon.

So CRS 12 I assume?

Noticed this in the Expedition 51 thread, from an ISS update dated April 28th:

Bigelow Expandable Activity Module (BEAM) Shield Installation:  The crew ingressed the BEAM and installed a Radiation Environment Monitor (REM) shield onto the REM sensor. This shield is a 1.1 mm thick component produced by the 3D printer on the ISS.  BEAM is an experimental expandable module attached to the ISS.  Expandable habitats greatly decrease the amount of transport volume required for future space missions. These “expandables” weigh less and take up less room on a rocket than a traditional module while allowing additional space for living and working. They also provide protection from solar and cosmic radiation, space debris, and other contaminants. Crews traveling to the moon, Mars, asteroids, or other destinations could possibly use them as habitable structures.
This was the first time that I had heard of the ISS crew printing a part to use on station instead of as a comparison to a ground-made part.  Are others aware of other examples?

In-Space industrialization is just a small step away.

For large amounts a DragonLab dedicated flight could produce quite a lot of fiber per flight. I believe the data was that 1 kg of source equates to 3km of fiber. So for 1 mt of fiber manufactured in a 2mt plant would produce 3,000,000 meters of fiber. At a sale price of $100/meter (that is less than the current price for the worst quality fiber) the revenue would be $300M. The cost of the flight of both the Dragon2 and F9 (both of which are reused) at about $100M/flight results in $200M profit. Because of the enormous amount of fiber this represents is why I used just $100/m for this supper quality fiber instead of its value when very little of it is available of $3,000/m.

If I had used the $3,000/m the revenue from a single flight would be $3B!!!!!!!!!!!!

So there is a lot of room for high costs of space travel.

With a Manned station the Dragons would transport just source and bring back finished fiber rolls ~3mt of fiber for support of prices as low as $30/M for $270M in revenue /flight. Enough to pay for not only the supply flights but for a pair of astronauts and the rental of a space station if 12 Dragon fiber delivery flights per year were made to the factory resulting in 108,000km of fiber produced per year at $30/m is $3.24B  in fiber. If all space launch costs are $2B then profit /yr would be $1.2B.

This could literally catapult a small company into a big player.

Thanks for your answer. So this seems very viable and truly a way to kickstart a space economy.

Thanks for pointing out the article.

It shows that the commercial industry has started the first big step in being able to manufacture in space prototypes to test without having to build them and then launch them from Earth. This saves time and money for prototype/space innovations. As the ability to manufacture in space larger/more complex and even metallic objects the acceleration of space innovations will start to show some payback for commercial space industry in increased capabilities for much lower costs.

From Expedition 51 thread:
ISS Daily Summary Report – 5/29/2017

Posted on May 29, 2017 at 4:00 pm by HQ.

Manufacturing Device (MD): The Manufacturing Device failed to complete the 12 hour print of a Radiation Environment Monitoring shield on Friday and during a second attempt yesterday. The REM shield was to be installed in the BEAM during ingress later this week. The Made-In-Space team is assessing the anomaly.  The MD – Additive Manufacturing Facility (AMF) enables the production of components on the ISS to meet both NASA and commercial objectives.  Parts, entire experiments, and tools can be created on demand utilizing the AMF.  The AMF is capable of producing parts using a wide variety of thermopolymers, including engineered plastics.
