Five Expensive Hobbies Where a 3D Printer Can Save You Money
Tech site Engadget looks at hobbies in which a home 3D printer can be cheaper than buying parts and accessories in stores. It also reminds readers to weigh costs, space and how often they would use one before buying.
Tech site Engadget has published a roundup of five hobbies in which a home 3D printer can save money, because parts and accessories can be printed instead of bought. The piece is aimed at readers considering such a device who want to know whether it would pay for itself.
How it works and what it costs
3D printing, also called additive manufacturing, builds three-dimensional objects from computer-aided design (CAD) models that can be downloaded online or created by the user. Entry-level printers such as the Creality Ender-3 V3 SE cost from about $170, while more advanced machines reach $700 or more. The most common printers use plastic filament, which costs from around $20 per kilogram. If someone makes 50 items worth $10 each from one kilogram of filament on a $170 machine, the printer pays off. Some libraries and maker spaces offer access to printers, and online services print for a fee.
Most home printers use FDM (fused deposition modeling), in which plastic filament, usually polylactic acid (PLA), is pushed through a heated nozzle. More expensive machines use resin (SLA/DLP) or polymer powder (SLS). Where fine detail matters, the article suggests an SLA printer.
The five hobbies
- Drones and remote-controlled vehicles. Spare parts such as camera mounts, antenna guards and arm protectors can be printed. Flight-critical parts like propellers should not be printed until the material, design and strength have been validated.
- Gardening and car repair. Garden signs, clips, planters, bird feeders, hard-to-find car interior pieces, knobs, tool organizers and wrenches can all be printed.
- Smart home. Cable management, wall mounts, housings for NFC stickers, and a chassis for a Home Assistant touch screen at a fraction of the price of Apple's $299 HomeView.
- Photography and video. Lens caps, cable clamps, battery holders, microphone and lighting mounts, and tripods.
- Tabletop games and models. Characters, buildings, trees and terrain for Dungeons & Dragons, plus model railroad parts. Fine detail calls for a resin printer.
What to consider
Before buying, the article advises thinking about how often you would use a printer, your skill level and the real running costs. Printers need good ventilation, so they should not be kept in a living room or bedroom. The best start is to use someone else's printer first.
