Mass Fabricator (GregTech 5)/en

The Mass Fabricator from is the machine that produces the UU-Matter used to replicate scanned elements. As it's placed in the world and connected to an energy source of its voltage, it starts to consume energy to produce UU-Matter, thus it's highly reccomended to use a or a  to prevent it to drain energy when not required. The UU-Matter is produced in fluid form, 1L at a time. Inputting UU Amplifier in the Mass Fabricator will reduce the processing time and the energy required of 4 times.

Recipe
Like every electric machine in GregTech, the Mass Fabricator comes in 5 variants, one for each voltage from Low to Insane.

Usage
The Low Voltage Mass Fabricator produces 1L(or 1mB) of Liquid UU-Matter within 160 seconds when no UU Amplifier is used. With UU Amplifier it takes 40 Seconds per 1L UU-Matter (1L UU-Amp used per produced 1L UU-Matter). The LV Mass Fabricator uses full 32EU/t when working, so because of losses, at last 2 Amp have to be supplied to it. Every higher tier of Mass Fabricators uses 4x as much EU/t while working twice as fast, so it needs twice as much EU per UU-Matter produced. So higher tiers of Mass Fabricators are inefficient and should only be used when energy used does not matter.

Since the Osmium needed to make the Mass Fabricator is usually rare in, it is often first used to replicate more Osmium. The full Setup with LV Mass Fabricator, LV and 1 scanned Osmium in  needs 7 Osmium to start. This first Osmium can only be obtained by processing Iridium Ore.

Osmium has an atomic weight of 190, so 190L UU-Matter are needed to replicate a single Osmium Dust. An LV Mass Fabricator needs 19,547,200EU and 8h29min to produce that. 4,886,800EU and 2h8min when supplied with 190L UU-Amplifier.

UU-Amplifier Efficiency
In an LV Mass Fabricator, 1L UU-Amplifier saves 77,160EU.

1L UU-Amplifier needs 9 Scrap, 9 Scrap need in average 72 recycled items.

An LV needs 5120 EU per 1L UU-Amplifier and  72 Items takes 3240 EU.

So every recycled item saves 956 EU. Producing enough UU-Amplifier for 1 Osmium Dust needs 13680 recycled items.

Inserting an (any configuration) into the Mass Fabricator will prevent it from running unless it is supplied with UU-Amplifier.

GregTech 5.09 Changes
In GregTech 5.09, the Mass Fabricator was changed to use 32V at 8 Amp for the LV version and can accept up to 10 Amps. Before 5.09 it was 1 Amp usage and 2 Amp max current.

This means that generating UUM consumes 8 times more EU, which makes Amplifier more important. This change was made to bring up the GregTech energy costs to equal the original IndustrialCraft 2 costs.

Another change is, that the higher tiers keep the same efficiency. Every tier higher means 4x Voltage, 0.5x processing time and 0.5x amp.

For example:
 * LV 32V, 160 sec, 8 Amp
 * MV 128V, 80 sec, 4 Amp
 * HV 512V, 40 sec, 2 Amp
