3D Printer chips, Furnace ingots and Gun Parts

The 3D Printer adds 24 progress a night and uses 8 energy, so a chip’s progress divided by 24 is its print time: one night for sights and springs, up to five nights for Combat Knives and Machetes. Fifteen chips print from filament or Scrap Metal on a stock printer. Metal magazines and metal melee weapons need a Metal Printer Module; Gun Parts and gun frames need both the Metal Printer and CNC modules, and both must sit in the module bay. All 24 chips are listed with inputs in the recipe table.

Getting a printer and chips

The Gunsmith start includes a worn printer with two modules stuck in its bay (a Glitched Module and an Eco Module). Otherwise buy Retired Gunsmith from Wild’s Network for 650 credits: the kit has a worn printer, a .22 Pistol chip and filament, and the Retired Gunsmith sells printers and chips weekly. Chips are not used up.

Chips by requirement

Requirement	Chips	Nights at base speed
None (filament)	Liberator pistol (×1 and ×2 chips), .22 magazines (three sizes), Small Plastic Bottle, Makeshift Red Dot Sight, Toy Laser Pointer	1–3
None (Scrap Metal)	Improved Internal Springs, Red Dot Sight, Laser Sight, Suppressor, Box Cutter, Kitchen Knife, Hatchet, Meat Cleaver	1–4
Metal Printer Module	10mm magazines (three sizes), Combat Knife, Combat Machete	2–5
Metal Printer + CNC modules	Gun Parts, Nestfire Compact Frame, Ironcraft 10 Frame	2–3

Update 1.0.0.12 made the Metal Printing and CNC modules work only from the module bay; a module left in the input or output grid no longer counts. Turbo boosters also can no longer go in those grids.

Furnace: Metal Ingots

The Furnace (200 credits from Dr. Jackson, offered on his first visit) turns 2 Scrap Metal or Metal Ore into 1 Metal Ingot each night and uses 8 energy. Ore is used before scrap, and the Furnace does not run if the output is full.

Input	Ingot purity	Ingot value
2 Scrap Metal	Low	−15%
1 Scrap Metal + 1 Metal Ore	Fair	50 credits (base)
2 Metal Ore	High	+25%
2 Ore + a Flux Smelting Agent	Very High	+50%
2 Ore + 200% Quality from modules	Perfect	+200%

• Flux Smelting Agent (Basic) costs 4 and adds one purity step; it is consumed only when it actually helps. The Advanced version (300) adds the same step and is never consumed.
• Every full 100% of module Quality adds one step. Flux and Quality do not stack; the Furnace uses whichever gives more.
• Blast module: 3 inputs become 2 ingots, one step lower. A flux agent cancels the penalty.
• Junk Processing module: on nights with nothing to smelt, 6 Junk become 4 Scrap Metal.

Metal Ore comes by phone from the GP Mining Coop (Wild’s Network, 250 credits).

Gun Parts

Ingot purity	Gun Parts per print
Very Low	2
Low or Fair	3
High or Very High	4
Perfect	5

One ingot per print, two nights. Two ore with a Basic flux agent gives Very High ingots, worth 4 parts each; Perfect needs 200% Quality on the Furnace. Taking a gun apart with a Screwdriver also gives 2–7 parts. Gun Parts repair used guns and finish printed frames into working guns.

Melee weapon condition

Each printed melee weapon gets a score: a random 20–30, plus a quarter of the printer’s Quality, plus an ingot bonus for ingot chips (Very Low −30, Low −20, Fair 0, High +20, Very High +30, Perfect +100).

Score	Condition
Under 25	Poor
25–59	Fair
60–89	Good
90 or more	Excellent

Worked example. A Combat Knife print from Very High ingots on a printer with +100% Quality scores 20–30 + 25 + 30 = 75–85: always Good. The same print from Perfect ingots scores 145–155: Excellent. Scrap-metal knives with no Quality score 20–30, so they come out Poor or Fair. A Melee Batch Module adds one weapon per melee print at the cost of 50% Performance and Efficiency.

Modules on the printer

Module	Effect
Metal Printer Module	Allows Metal Printing chips; Efficiency −50%.
Computer Numerical Control Module	Allows CNC chips; Performance −25%, Efficiency −25%.
Melee Batch Module	+1 melee weapon per print; Performance and Efficiency −50%.
Performance, Overclock	More progress per night.
Efficiency, Eco	Less energy per night.
Quality	Counts at a quarter on the printer: raises melee and frame condition and printed gun stats.

Since 1.0.0.12 the Printer and the Furnace’s Blast module spill finished items into the store when their output is full. More on module shapes and stacking in the modules guide.
