The Sawmill is a machine added by Thermal Expansion 5. It is used as a more efficient method of obtaining planks from wood, yielding 6 planks instead of the standard 4 planks in the crafting table recipe. It can also deconstruct many wooden objects into planks.

The Sawmill has one input (blue), a primary output (red) and a secondary output (yellow). These can be changed to different faces using the Configuration menu in the machine's GUI. It is possible to use two faces of the machine for the same output, or have primary and secondary products output to the same face (orange).



Sawing a log will give one Sawdust as a byproduct in the lower output cell. Sawing other items may result in other byproducts at a percentage chance (for instance, sawing eight Sugar Canes will produce a Pulped Biomass with a 100% chance for two Sugar). Most plant-type items (saplings, crops, etc.) can also be sawed into Pulped Biomass.


A Sawmill can accept the following Augments:

Image Name Type Description

Auxiliary Reception Coil Augment Increases max power usage (speed) at the cost of higher power use per operation. Stackable. Multiplies max power usage by 1+n, where n is the amount of coils installed, and increases power use per operation by 10% per coil.

Auxiliary Sieve Augment Increases the chances of producing a secondary product at the cost of higher power use per operation. Stackable. One sieve multiplies the chance by 1.18x, increasing up to a maximum of a 20x multiplier at 7 sieves installed. Each sieve increases power used per operation by 10%.

Nullification Chamber Augment Destroys secondary products when the secondary output slot is full. This allows the machine to keep working despite a full secondary slot.

Resin Funnel Specialization Extracts fluids from wood. The fluids extracted depend on the type of wood, and correspond to the fluids produced by the Arboreal Extractor. The amount of fluid produced is equal to the amount the Arboreal Extractor produces divided by 5. The Sawmill consumes 50% more power per operation. This augment also adds a 4-bucket internal tank to the Sawmill, which can be configured to output to any side, sharing the color of the secondary output (yellow).


A Sawmill is crafted at the lowest tier (Basic). It can be upgraded to higher tiers using Upgrade Kits. As it is upgraded it is able to use more RF per tick, which allows it to process items faster. Upgrading also adds augment slots, and increases the input and output rate of items and fluids.
