Epoxy

Check the inputs. Make a plan. Bring only what you still need.

Selected recipe · Compounder

The source rate is 40 Epoxy per minute. The table below converts each input rate into its theoretical cost per output item. Rates are reference ratios, not a promise about real-world completion time.

Ingredient	Input per minute	Per output item
Liquid Helium	20	0.5
Goethite Powder	40	1
Synthetic Resin	20	0.5

Default source recipe: compounder:7. Other machine tiers and alternative recipes may use different proportions. This planner selects the first default source recipe for each output.

Compare included machine tiers

This snapshot includes 2 default machine recipes for Epoxy. Compare each recipe's direct input-to-output proportions below. The planner and every example on this page still use the first default recipe, Compounder; this table does not change that selection or optimize the dependency chain. Explicit alternative recipes are excluded, and these rows do not establish unlock requirements, discrete craft batches, construction costs, or completion times.

Included default recipes; material amounts are per output item.
Machine	Source output/min	Direct inputs per output	Planner selection
Compounder `compounder:7`	40	0.5 Liquid Helium 1 Goethite Powder 0.5 Synthetic Resin	Selected default
Compounder v.2 `synthetizertier2:epoxy_v2`	120	0.333 Liquid Helium 0.333 Goethite Powder 0.333 Synthetic Resin	Reference only

Worked example: plan 10 Epoxy

With no inventory, the selected recipe chain expands to the terminal resources below. The plan contains 22 production steps. Theoretical amounts retain fractions; the gathering column rounds each resource up once. Real craft batches may need additional inputs.

Reference resource budget for 10 Epoxy, before inventory
Terminal resource	Theoretical amount	Rounded gathering amount
Calcium Ore	12.813	13
Goethite Ore	0.25	1
Helium-3	13.125	14
Sulphur Ore	35	35
Titanium Ore	2.813	3
Wolfram Ore	4.792	5

What uses Epoxy?

The selected default recipes below directly consume Epoxy. Open an output item to inspect its complete dependency chain.

Uberfilament — 1 Epoxy per output item, using Assembler.
Explosive Charge — 1 Epoxy per output item, using Assembler.
Pseudorubber Insulator — 1 Epoxy per output item, using Assembler.
Anti-Radiation Covers — 2 Epoxy per output item, using Constructorizer.
Heat Shield — 1 Epoxy per output item, using Mega Press.
Ion Stabilizer — 1 Epoxy per output item, using Mega Press.
Organic Compound — 0.333 Epoxy per output item, using Compounder.

Before you build

The plan combines shared ingredient demand and consumes your inventory once across all targets. Enter any finished parts you already own before collecting raw materials. Rounded gathering quantities are an allowance over theoretical ratios; actual discrete craft batches may need additional supplies.
