PrusaSlicer and Simplify3D compared for makers, with LunarWerx 3D Print: what each does, price, setup, and what to check.

By TexHouse · 2026-10-18

TexHouse is published by the makers of LunarWerx 3D Print, Vector3D and MeshyDL, which are compared here alongside other tools.

PrusaSlicer provides 200+ tested profiles. ^[1] LunarWerx 3D Print is a set of free browser tools that work out ironing settings, check a part for injection moulding and design 3D-printable foam inserts. ^[2]

If you want software that runs on Windows, macOS and Linux, PrusaSlicer's page lists all three. If you want a tool with no account, PrusaSlicer is free and needs no account. If you need ironing settings exported as a ready 3MF file, the LunarWerx claims say it does that. The two tools can be looked at as different jobs rather than strict replacements.

The table shows the Simplify3D facts used for this comparison. A maker can compare the listed claims with the needs of the project.

What LunarWerx 3D Print is built for

LunarWerx 3D Print is made by the team that publishes this site. It is a set of browser tools for ironing settings, injection moulding checks and foam inserts. ^[2]

The ironing helper works out settings for your printer, material and finish and exports a ready 3MF file. ^[2] It makes a 9-pad or 16-pad test plate, and you mark each pad as worked or not. ^[2] You can click flat top surfaces, and the export adds a modifier part over each picked surface. ^[2]

The mould helper runs 13 checks, shows shrinkage, pressure and weak-point maps, and builds the two mould halves; all numbers are estimates. ^[2] The foam tool lays parts out in a box and designs a foam tray and top pad that each part lifts out of. ^[2] It also turns backwards faces in an STL file right side out and says how many it fixed. ^[2]

Setting it up and printing

PrusaSlicer's page lists Windows, macOS and Linux, and its Windows build for 2.9.6 is 64-bit. ^[1] ^[1] Where it runs is all these allowed facts say about setup, so check its own page for installation steps.

LunarWerx 3D Print runs in a web browser. ^[2] You use it on its website, which is hosted on Cloudflare. ^[2] It runs only in your browser; sign in with Connections and your settings, recent test plates and print results follow you to every computer. ^[2] For your slicer, an uploaded Bambu or Orca project gets per-object ironing settings, and the rest of the file stays unchanged. ^[2] One checkbox slows just the first layer to 15 mm/s by default. ^[2]

Simplify3D's setup details are not given in the facts gathered here, so check its own page for how to install it and connect a printer.

Things to check before you choose

Ask which computer you use, since PrusaSlicer lists Windows, macOS and Linux. ^[1] Check Simplify3D's own page for what systems it runs on and what its price is, since neither is published in the facts here.

Ask whether a browser tool suits your workflow, since LunarWerx 3D Print runs in a web browser. ^[2] If you want to see the code of the tool you use, check each one's licence. The LunarWerx 3D Print code package is marked private, not public. ^[2] Mould numbers are estimates, so decide how much weight to give them. ^[2]
