## The short answer

A slicer helps turn a 3D model into instructions for a 3D printer. OrcaSlicer is a free tool for FDM 3D printers. [^1] PrusaSlicer is free and does not require an account. [^2]

OrcaSlicer says it provides adaptive bed mesh calibration and per-feature overrides for speed, layer height, pressure, and temperature. [^1][^1] PrusaSlicer says it provides tested profiles. [^2]

LunarWerx 3D Print is a browser based tool that works out ironing settings and exports a ready 3MF file. [^3][^3]

## What OrcaSlicer and PrusaSlicer are built for

OrcaSlicer describes itself as a free slicer for FDM 3D printers. [^1] It supports Windows, macOS, and Linux. [^1]

OrcaSlicer provides wall and seam control, smart supports, and per-feature overrides for speed, layer height, pressure, and temperature. [^1] [^1] [^1]

OrcaSlicer's page also describes adaptive bed mesh calibration, which probes only the region your print occupies. [^1] It lists automatic mouse-ear brims that hold corners down on warp-prone prints. [^1] It says you can set speed, layer height, pressure, and temperature independently for walls, infill, supports, and more. [^1]

PrusaSlicer describes itself as a feature rich tool that is frequently updated. [^2] It runs on Windows, macOS, and Linux. [^2]

PrusaSlicer provides 200+ tested profiles for every Prusa printer and every filament. [^2] It also lists automatic profile updates through the built in updater. [^2]

## What LunarWerx 3D Print is built for

LunarWerx 3D Print is made by the team that publishes this site. It runs in a web browser. [^3]

LunarWerx 3D Print works out ironing settings for your printer, material, and finish and exports a ready 3MF file. [^3] It makes a 9 pad or 16 pad test plate around your settings, and you mark each pad as worked or not. [^3]

You can click flat top surfaces, and the export adds a modifier part over each picked surface. [^3] For an uploaded Bambu or Orca project, it adds per-object ironing settings and keeps the rest of the file unchanged. [^3]

It can also turn backwards facing faces of an STL outward and tell you how many it fixed. [^3]

One checkbox slows just the first layer to 15 mm/s by default; LunarWerx 3D Print says it then sticks to a clean plate without glue. [^3] For shipping parts, it lays them out in a box and designs a 3D printable foam tray and top pad. [^3] The foam insert is split into pieces that each fit your printer's bed. [^3]

## Pricing and fees

OrcaSlicer is described as free. [^1] PrusaSlicer is described as free and no account is required. [^2] LunarWerx 3D Print tools are free to use. [^3]

The facts gathered here state no card fee for any of the three tools. A maker should check each tool's own page for current terms, and confirm whether any add-on or service they want carries its own cost.

## Things to check before you choose

Ask these questions before choosing a tool:

- Does it support the printer, material, and workflow being used?
- Does it provide the calibration or preparation tools needed?
- Does it need an account or work without one?
- Which operating system does it support?
- How does it move print files to the printer?
- Does it work with existing project files?
- Are the settings and exports suitable for the way the printer is used?
- Does the tool keep working when the internet is down, and does that matter for your workshop?
