Kiri:Moto and OrcaSlicer compared for makers: what each one's sources say, price, setup, and what to check before you choose, with LunarWerx 3D Print as a third option. | Option | What it does | Price | Where it runs | |---|---|---|---| | Kiri:Moto | Its page describes it as a project for makers, hobbyists, professionals, students, and educators [^1] | not published | not published | | OrcaSlicer | Slicer for FDM 3D printers [^2] | Free [^2] | Windows, macOS, and Linux [^2] | | LunarWerx 3D Print | Browser tools for ironing settings, injection moulding checks and foam inserts [^3] | Free to use [^3] | In a web browser [^3] | ## The short answer A slicer is the program that turns a 3D model into the instructions a printer follows. Many home printers use the FDM method, which melts plastic and builds a part one thin layer at a time. OrcaSlicer is a free slicer for FDM 3D printers. [^2] Its page says calibration tools are built in. [^2] Kiri:Moto's page describes it as a project for makers, hobbyists, professionals, students, and educators. [^1] The sources gathered for this page do not say what Kiri:Moto is built to do for a maker, so check its own pages before you decide. LunarWerx 3D Print is a set of browser tools for ironing settings, checking a part for injection moulding and designing 3D-printable foam inserts. [^3] Ironing is a finishing pass that smooths the top surface of a print. If you want ironing settings exported as a ready 3MF file, LunarWerx 3D Print says it does that. [^3] ## What Kiri:Moto, OrcaSlicer is built for OrcaSlicer's page says it supports Windows, macOS, and Linux. [^2] It is licensed under AGPL-3.0, a software license. [^2] Its page lists calibration tools built in, with tests for flow rate, pressure advance, temperature towers, retraction, tolerance, and maximum volumetric speed. [^2] [^2] For first layers, it lists adaptive bed mesh calibration, which probes only the region your print occupies so first layers stay accurate without a full-bed level on every job. [^2] For prints that tend to warp, where corners curl up off the plate, its page lists automatic mouse-ear brims that hold corners down and are easy to remove. [^2] It also lists smart supports, with overhang detection and support placement for complex shapes. [^2] Its page lists wall and seam control, sandwich mode for alternating wall and infill order, and settings for speed, layer height, pressure, and temperature that can differ for walls, infill, supports, and more. [^2] [^2] [^2] Kiri:Moto's page describes it as a project for makers, hobbyists, professionals, students, and educators. [^1] Its page lists Releases & Binaries, so the makers it is meant for can get its builds from there. [^1] The sources gathered for this page do not say what Kiri:Moto is built to do for a maker, so read its own pages for that. ## 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. [^3] The ironing helper works out settings for your printer, material and finish and exports a ready 3MF file. [^3] It makes a 9-pad or 16-pad test plate, 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] The mould helper runs 13 checks, shows shrinkage, pressure and weak-point maps, and builds the two mould halves; all numbers are estimates. [^3] The foam tool lays parts out in a box and designs a foam tray and top pad that each part lifts out of. [^3] The foam insert is split into pieces that each fit your printer's bed. [^3] When you open an STL file with faces turned backwards, it turns them right side out and says how many it fixed. [^3] ## Pricing and fees | Option | Price | |---|---| | Kiri:Moto | not published | | OrcaSlicer | Free [^2] | | LunarWerx 3D Print | Free to use [^3] | Kiri:Moto's page says it accepts support for development. [^1] The sources gathered for this page do not publish a price for Kiri:Moto, so check its own pages for any cost. OrcaSlicer's page describes it as free. [^2] The sources gathered list no other fee for it. LunarWerx 3D Print says its tools are free to use. [^3] No card fee or add-on fee is published for any of the three options in these sources. ## Setting it up and printing OrcaSlicer runs on Windows, macOS, and Linux. [^2] Its page says it can send jobs to and monitor printers running Klipper, PrusaLink, or OctoPrint. [^2] These are control programs that run on some home printers, so check which one your printer uses. Kiri:Moto's page lists Releases & Binaries. [^1] The sources gathered for this page do not say which computer systems it runs on, so check its own pages before you install. LunarWerx 3D Print runs in a web browser. [^3] You use it on its website, which is hosted on Cloudflare, a web hosting company. [^3] It runs only in your browser; signing in keeps your settings, recent test plates and print results across every computer. [^3] For your slicer, an uploaded Bambu or Orca project gets per-object ironing settings, and the rest of the file stays unchanged. [^3] One checkbox slows just the first layer to 15 millimetres per second by default, which LunarWerx 3D Print says helps the print stick to a clean plate without glue. [^3] ## Things to check before you choose Ask which job you need done: calibration and printer control, or settings and design helpers. Ask which computer systems you use, and check that against what each tool's sources list. OrcaSlicer's sources list Windows, macOS, and Linux.
