3D Printing Zone

In 2022 a two-year-old Shenzhen start-up founded by ex-DJI drone engineers put a printer on Kickstarter and raised about seven million US dollars in a month. Four years later Bambu Lab ships more entry-level 3D printers (under US$2,500) than anyone on earth, its model site MakerWorld claims ten million monthly users, and a Texas jury has just ordered it to pay Stratasys 27.6 million US dollars for patent infringement. This episode tells the story: what the X1 actually changed, how the price of a "just works" multicolour printer fell from 1,200 to 300 US dollars, and what the industry gave up along the way. You'll come away understanding what CoreXY, lidar and an AMS are and why they mattered; how Bambu went from a Kickstarter to a 37 percent share of entry-level shipments; how MakerWorld's points system rewired the free-model economy; the August 2023 "ghost print" cloud outage, the A1 heatbed recall, the January 2025 firmware lock-down, the 2026 open-source licensing fight with Prusa and the Software Freedom Conservancy, and the Stratasys verdict; and what all this means for a hobbyist buying a printer, or a business ordering a print, in Australia in late 2026. Fair, sourced and honest about both the engineering and the controversies. Need something printed?

Walk into any filament shop, online or otherwise, and plain PLA is surrounded by cousins: silk, matte, glow-in-the-dark, wood, marble, carbon fibre, sparkle, rainbow, colour-changing, and the mysterious "PLA Plus". They are all PLA underneath, yet a silk vase and a matte figurine print, feel and break quite differently. This episode goes finish by finish and explains what the additive actually is, what it does to the print, and what it quietly costs you in strength, nozzle wear or dollars. You'll come away understanding why silk filament is glossy but can lose most of its layer strength; why matte PLA is heavier than plain PLA and hides layer lines; what strontium aluminate is and why glow filament needs a hardened steel nozzle; how dual-colour silk changes colour as you turn it; what the "plus" in PLA Plus really buys; and the one thing none of these finishes change, which is how PLA behaves in a hot car or in the Australian sun. Ideal for anyone choosing a finish for a gift, a sign, a cosplay piece or a display model, and for makers wondering why their shiny print snapped along a layer line. Need something printed?

The week of 26 September to 4 October 2026 in 3D printing, for makers and small businesses. California signed a law that will one day require printers to recognise and refuse gun files, Bambu Lab launched a matte PETG at the same price as its glossy one, Prusa put a 400-degree hotend on the Core One, Creality announced a laptop-free blue-laser scanner, E3D turned its high-flow nozzle patents into a licensing badge, a three-year-old 3D-printed planter business got bought by a private-equity-backed décor brand, and the first rocket thrusters printed in orbit came home for testing. Plus two Australian research stories.

A dishwasher basket wheel snaps, a fridge shelf clip crumbles, the bracket on a roller blind gives way, and suddenly a perfectly good appliance is heading for the kerb over a few grams of plastic. This episode is about the most useful thing a 3D printer does in an ordinary home: making the small part nobody sells any more. We walk through real examples, how to find or create a model, which material suits which job, how to design a part that actually fits, where the safety limits are, and how right-to-repair law in Europe and Australia is shifting the ground under manufacturers. You'll come away understanding the four ways to get a model for a broken part (searching model sites by part number, measuring with a $20 digital calliper and drawing it yourself, scanning or photogrammetry, and the small but growing list of manufacturers such as Philips and Miele that publish official files); which material to choose, from PLA for indoor low-stress parts to PETG and ASA for heat and sun, TPU for flexible feet and gaskets, and resin for tiny detailed gears; the design rules that make parts fit and last, including 0.2 to 0.4 mm clearances, orienting the print so layer lines do not carry the load, and making the part thicker than the original; the list of things you should not print, from anything safety-critical or pressurised to food-contact items and high-heat locations; and where the EU Right to Repair Directive and Australia's Productivity Commission recommendations have actually landed as of 2026. For anyone who has ever stared at a broken clip and wondered whether the whole appliance really needs replacing, plus a practical tip: print a quick test coupon of the critical dimension before committing to the full part.

Millions of free 3D models are a click away, but where do they come from, who pays the people who design them, and what are you actually allowed to do with a file once you have downloaded it? This episode walks through the big model sites, from Thingiverse's 2008 origins and 2026 rescue to Printables' Prusameters and MakerWorld's points and one-click print profiles, then unpacks the licence line on every model page in plain language. You'll come away understanding how Thingiverse, Printables, MakerWorld, Cults3D, MyMiniFactory, Thangs and Patreon differ and how each one makes money; how designers are rewarded through points, boosts, tips, paid files and subscriptions, with real figures; what a 3MF print profile is and why it made one-tap printing possible; what the Creative Commons letters BY, NC, SA and ND mean, what "non-commercial" does and does not cover, including paying a service to print for you; how MakerWorld's Standard Digital File License and miniature "merchant tiers" differ from Creative Commons; and how to spot a model worth printing before you spend the filament. This one is for anyone who downloads models, whether you own a printer or not. Practical tip: if a model is colour-painted, download the 3MF rather than the STL so the colour data survives, and post a photo of your finished print on the model page. It costs nothing and it is how designers earn. General information only, not legal advice. Need something printed?
