Assembly Line
ModGregTech 5 Unofficial
TypeMultiblock machine

The Assembly Line is a multiblock machine added by GregTech 5 Unofficial, used to craft LuV and above components.


The Assembly Line can be 5–16 blocks long. The minimum length requires depends on the number of components and fluids required by the recipe it's crafting. The Data Access Hatch or Advanced Data Access Hatch next to the controller is optional; it can be replaced with a Grate Machine Casing.


To get the recipe for an item one must scan the item for a voltage tier lower than it in a Scanner. This will consume the item. The analyzed data stick can then be taken to a Printer to obtain Printed Pages, which can then be crafted into a Construction Data book in an Assembling Machine.

This Construction Data book will contain information on how much power a recipe requires as well as what fluids and items need to be inserted into the input hatches or buses.

To perform a recipe with the Assembly Line, a Data Stick containing corresponding analyzed data needs to be placed either in the top-right slot of the controller, or in the Data Access Hatch or the Advanced Data Access Hatch.


Unlike most other multiblock machines from GregTech 5, the Assembly Line follows the standard rule of overclocking penalty.

Tips on automation

Since Assembly Line recipes require a specific item stack (or fluid) to be put in a specific input bus (or hatch), it is generally hard to automate the machine even with the help of dedicated automation systems such as Applied Energistics 2. One way to automate it is to use Steve's Factory Manager which can observe an input chest to see if it has a combination of materials to perform a recipe, then move items in the input chest to each of the correct input buses. One can then dump materials in the input chest with, for example, Applied Energistics 2 and let Steve's Factory Manager do the rest.

Some of the Assembly Line recipes require more than 9 item stacks, which is problematic for Applied Energistics 2 because it can only handle up to 9 item stacks for one recipe. To work around the limitation, one can use a dummy item as a "token", such as chiseled Dirt. The token needs to be an item that is highly unlikely that a player would want to put in AE2 storages. Create a processing recipe which "crafts" the token with a part of required materials to perform the actual recipe. By "craft" it means SFM gives AE2 the token in exchange for the specific subset of required materials. Then create another processing recipe which crafts the actual result with the remaining part of the materials and the token. SFM takes the token, combines materials separately sent from AE2, sends them to input buses and hatches, and keeps the token for the next crafting request.
