Forget about it for plastics unless you get to the higher power Diodes at 10W or more. Seriously consider the overall cost of a build including preferably a full enclosure and laser proof plastics windows or goggles and some form of extraction.

The entry level K40 has some 'quirks' and needs some mods to help it get good results. Partial thread of my improved toy here 3-4mm Acrylic no problems and some other plastics too along with Balsa and 3mm Ply or MDF. As I had an unresolved issue with the supplier on some shipping damage I haven't added any further posts to it but the laser itself cuts really well. https://www.eevblog.com/forum/reviews/40w-300x200mm-laser-cutter-engraver-vollerun/msg1665956/#msg1665956

Metal of any sort needs 100W+ and generally a lot more if not a specific style of laser for some metals.
