Having recently discovered and fallen in love with 3D printing, I’ve compiled a list of resources for 3D printing software, supplies and parts.
GST3D – Low cost PLA+ 3D printer filament in a variety of colors. Prints reasonably well, and the company ships fairly quickly.
Overture 3D – PLA, PLA Silk, PETG, ASA, ABS, TPU, Nylon filaments. Also carries nozzles, and build surfaces.
Sunlu – PLA, PLA Silk, PETG, SPLA, ABS, Carbon Fiber, Wood, TPU filaments, including some rainbow and shiny filaments. Also sells filament dryer boxes, 3D pens, and a line of 3D printers.
Xvico – PLA and PETG filaments, as well as a range of 3D printers.
Matter Hackers – ABS, ASA, SLA, PETG, Nylon, TPU. Medium to Professional quality filaments, with accompanying elevated pricing. Also printers, and replacement or upgrade parts.
3D Filament Source – PLA, PETG, ABS filament. Includes some of the more pastel colors, reasonably priced.
Toolots – Low cost filaments – ABS, PLA, PLA Silk, PLA+, PETG, TPU, Rainbow, Glow in the Dark, Wood. Also carries 3D printers of a more industrial type.
3D Fuel – PLA, PETG, ABS, ASA, Nylon filaments. Mid-priced. Wide array of colors and shades.
eSun – Wide variety of filament types and colors.
Eryone – Nice assortment of PLA and PLA+, PETG filaments, including some gorgeous metallic, rainbow, marble, wood and silk colors.
Thingiverse.com – One of the biggest repositories for free 3D models you can download and print. Tends towards the useful objects.
Thangs.com – Big source of 3D printed models though there are more figurines than useful things.
Cults3D – Mix of free and paid STL files in many different categories.
Prusa – Well categorized downloadable models and gcode files at the Prusa printer site.
My Mini Factory – Mix of free and paid models with a heavy bent towards figurines.
GrabCad – Over 4 million models. Not all are suitable for 3D printing, but many are useful to design other components around, such as a raspberry pi model to help design a case.
McMasterCarr – Huge engineering and mechanical parts provider that has CAD models downloadable of most of their parts.
Great places to get advice and troubleshooting tips for your 3D printing and modeling.
