Fabricator

Assembles finished parts from several refined materials at once. A script picks a recipe, gathers each ingredient into its shared stockpile, and drains the finished items out.

Stats: Power in variable · Steam/Water/Oil buffers 10 t each · Output buffer 20 · Byproduct buffer 20 · Stockpile 200 (mixed) · Recipes 69 available

How to obtain: Requires the Fabrication research (Terraform Index 130,000). Buy from the Shop for 1,400 cr.

Access: self / get_component(id) · Like every component, exposes .id and .name.

Methods

.outpost

The outpost where this building is deployed, as an OutpostRef.

.list_recipes()

Every recipe this fabricator has been given a blueprint for. Returns Recipe objects with .tier, .id, .name, .inputs, .output_item, .output_count, .duration_game_hours, .power_draw, .fluid_inputs (tons consumed per run), and optional byproduct fields. Locked recipes (no blueprint yet) do not appear: the list reflects what the player can actually craft today. sorted(self.list_recipes(), key=lambda recipe: recipe.tier) orders the available queue from foundations upward.

Returns: List of unlocked Recipe objects

.find_recipe(recipe_id)

Find one unlocked recipe by id without looping through list_recipes(). Returns its Recipe object, or None when the id is unknown, locked, or belongs to another machine.

Returns: Recipe or None

.set_recipe(recipe_or_id) SELF ONLY

Select which recipe to assemble: self.set_recipe("craft_gas_pipe_segment"), or pass a Recipe from list_recipes(). Setting a recipe doesn’t clear the stockpile, so leftovers from a previous recipe stay until consumed or self.input.flush() discards them.

Returns: ActionResult · Outcomes: "ok" / "unknown_recipe" / "offline" (transient) / "recipe_locked" / "busy" (transient) / "material_mismatch"

.clear_recipe() SELF ONLY

Unset the selected recipe and leave the Fabricator idle. The input stockpile is preserved because it is general staged material, not the selected recipe.

Returns: ActionResult · Outcomes: "ok" / "busy" / "material_present"

.get_recipe()

Current recipe id as a string, or the empty string if no recipe is set. The 69 recipe ids span pipes and bridges (craft_gas_pipe_segment, craft_liquid_pipe_segment, craft_power_line_segment, the three bridge kits), core components (craft_machine_frame, craft_circuit_panel, craft_control_unit, craft_battery_cell, craft_pressure_valve, craft_turbine_rotor, craft_tank_lining), kits (craft_thermal_cap_kit, craft_water_pump, craft_oil_pump, drone station kits, mining drill kits, craft_seed_maker_kit, craft_plant_terraformer_kit, craft_grow_lamp_kit, craft_sprinkler_kit, craft_dispenser_kit, craft_garbage_disposal_kit, craft_exotic_gas_cap_kit, craft_exotic_spring_tap_kit, craft_lead_cask, craft_lightning_rod_kit), oil products (craft_lubricant, craft_plastic, craft_rubber, craft_tar), drone hardware (chassis sizes, thrusters, cargo pods, battery pack, oil tanks), advanced materials (craft_reinforced_biopolymer, craft_enrichment_compound, craft_coolant_loop, craft_neutron_capacitor, craft_lead_plate, craft_shield_plating), field treatments (fertilizers Mk I-III, craft_growth_accelerant, craft_yield_amplifier), and upgrade packs (Plant Terraformer Mk II, Grow Lamp and Sprinkler Mk II/III, craft_habitat_pack_mk2, the Mk IV atmosphere packs). See Fabricator Recipes for the full table.

Returns: String (recipe id, or empty string)

.get_recipe_inputs()

Input requirements for the current recipe as a dict {item_id: count_per_craft}. Empty dict if no recipe is set.

Returns: Dict

.get_stockpile()

Current stockpile contents as a dict {item_id: count_currently_stored}.

Returns: Dict

.get_stockpile_used() / .get_stockpile_capacity()

Total units across every material in the stockpile, and the combined cap. When full, further input is blocked until the running craft consumes some material.

Returns: Number

.is_running()

True while a craft is in progress. Use before set_recipe() to avoid "busy", or to show status.

Returns: Boolean

.get_progress()

Progress toward the current craft’s completion (0-1). Resets to 0 when a craft finishes.

Returns: Number (0-1)

.get_output_count()

Completed units waiting in the output buffer. Drain them via self.output.send(...) before the buffer fills: processing stalls when the output is full.

Returns: Number

.input

Input I/O port feeding the multi-material stockpile. Inventory works at home only; remote Fabricators connect local stores and may switch between them for each ingredient. Transfers require Auto Feeders research. See InputSlot.

.output

Output I/O port for finished items. Inventory works at home only; remote Fabricators connect a local Storage Bin or Warehouse. See OutputSlot.

.byproduct

Secondary output port for byproducts. Most recipes only emit through self.output; oil-refining recipes (lubricant, plastic, rubber) emit tar here on every craft. Same API as self.output.

Warning

The byproduct bin must have space for the next craft, otherwise the recipe stalls. Keep this drained, not just self.output.

.steam_in / .water_in / .oil_in

Internal process buffers (10 t each) for recipes that declare the matching fluid_inputs. Call connect(...) with a compatible provider’s stable machine id or display name. A local source transfers directly; a remote source also needs a completed conflict-free pipe route between both locations. Read level() / flow_rate() to detect starvation. Recipes consume from the buffer on craft completion. See FluidPort.
