The short answer

A maker comparing printing tools starts with what each one does. OrcaSlicer is free slicing software for FDM 3D printers. [1] Simplify3D develops premium 3D printing software. [2] 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. [3] [3]

For a free tool, OrcaSlicer's page says it is free slicing software for FDM 3D printers. [1] For faster slicing, Simplify3D's page states 3.0x faster slicing performance. [2] For a browser helper that costs nothing, LunarWerx 3D Print says its tools are free to use. [3] The three answer different jobs rather than strict replacements.

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 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]

The mould helper runs 13 checks for injection moulding, 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 3D-printable foam tray and a top pad that each part lifts straight out of. [3] If the insert is too big for the bed, it is split into pieces that each fit your printer's bed. [3] It also turns backwards faces in an STL file right side out and says how many it fixed. [3]
