Spec score 7.6 #18 of 42 in Minecraft Schematic Tools

What it is

Seija-Printer is a free, open-source Minecraft mod for printing blocks and fluids from Litematica schematics while you play. It simulates placement on the client and compares selected block-state properties with the schematic before placing the intended state. Meteor Client and Litematica are required. Configuration can allow midair placement and states that differ from the player’s facing direction on servers without anti-cheat plugins. Face-detection and ray-tracing checks are available for servers with anti-cheat. Block replacement substitutes custom blocks for schematic blocks, Bridge mode attempts to add supports around suspended blocks, and Surface mode prints a chosen number of outer schematic layers. Fluid placement is unstable and may put fluids in wrong locations, so the README recommends enabling it after construction. Simulation is performance intensive, and a large placement range may crash the game. The maintainer describes the project as close to semi-discontinued but plans to adapt it to newer Minecraft versions.

Who it suits

It suits Minecraft players who already use Meteor Client and Litematica and want schematic-based construction in-game. It also offers controls for server configuration, replacement blocks, bridges, and surface layers.

Verdict

Seija-Printer provides extensive schematic-printing controls for players with its required dependencies. Performance, fluid reliability, licensing restrictions, and uncertain development status should be considered first.
