Have you ever marveled at a beautifully intricate 3D-printed model and thought, “I wish I could create something like that!” With 3D printers becoming rapidly more affordable (you can get a basic starter model for $200-300 these days), bringing the world of additive manufacturing into your home is easier than ever. Read on to learn if now is the right time to finally get your desktop fabrication tool!
Unlike traditional subtractive manufacturing, which cuts away material, 3D printing builds up objects layer by layer using a digital file. The most common technique affordable consumer models use is fused deposition modeling (FDM), where thermoplastic filament, usually ABS or PLA, is heated and extruded through a nozzle onto a print bed.
Other methods like stereolithography (SLA) and selective laser sintering (SLS) use ultraviolet light or a laser to cure liquid resin or fuse powdered material. The type of 3D printing technology determines what materials can be used. FDM printers are mainly limited to various plastics, but other techniques can print with metals, ceramics, and more.
| Method | Materials |
| FDM | Plastics like PLA, ABS, PETG |
| SLA | Resins |
| SLS | Metals, Ceramics |

So, what are the benefits of getting your own desktop fabrication device versus outsourcing to a 3D printing service?
Having your own 3D printer is like owning your own mini manufacturing facility – you can create completely customized objects tailored to your needs and wants! Whether it’s accessories, tools, decor, models, or replacement parts, you can design and print them on demand instead of waiting for something to ship.
Got a broken knob on your stove? Just print a new one! Want a personalized phone case? Design your own and print it! Need a unique gift? 3D print something one-of-a-kind!
It’s often cheaper to 3D print small plastic parts and objects than to buy something mass-produced. Printing your own custom items means you don’t have to keep re-ordering and paying for shipping and packaging. DIY repairs through 3D-printed replacement parts can save money, too.
Over time, printing your own goods can lead to significant cost savings compared to continually buying and ordering them
Owning a 3D printer provides excellent opportunities for learning, creativity, and inspiration. The entire process of designing objects in 3D modeling software, preparing files for printing, operating the printer, and post-processing builds valuable technical skills. Kids and adults alike can benefit from STEM educational opportunities. Plus, it’s just plain cool to see your digital creations come to life before your eyes!
While 3D printing has some awesome benefits, it also comes with some limitations to keep in mind.
Desktop 3D printers can cost from a few hundred dollars to several thousand dollars for more advanced models. While prices have decreased significantly, they’re still an investment, especially if you opt for a higher-end or large-build volume machine. Research and shop for a starter printer that fits your needs and budget.
From leveling the print bed to removing supports and dialing in settings, 3D printing has a learning curve. Expect to go through some trial and error while getting the hang of operating a printer and tweaking models to print properly. Be prepared to spend time learning the software and processes for the best results.
Affordable FDM printers are restricted primarily to various plastics. Other materials like advanced polymers, composites, or metals require more expensive printers. Even printing with standard PLA and ABS has more limitations than injection molding. Keep material capabilities in mind.
Desktop 3D printers take up a moderate amount of space. You’ll need a sturdy table or desk to accommodate the printer and storage for the plastic filament spools. Printers are relatively safe to run but require supervision, so keep the space in mind.
If you’re ready to take the plunge into the world of desktop fabrication, here are some tips for getting started on the right foot:
Proper setup and calibration are crucial to get successful prints. Take your time learning the ropes. Start simple, be patient, and have fun with your first 3D printing projects! The learning journey itself is enriching.
While it does require an initial investment and learning curve, owning a desktop 3D printer gives you the power to create just about anything imaginable out of digital files right from the convenience of home.
Prices of beginner models have dropped significantly in recent years, putting affordable home fabrication within reach of DIY enthusiasts, tinkerers, hobbyists, and entrepreneurs. If you’re curious about experiencing this fascinating technology first-hand, now may be the perfect time to try out your very own starter 3D printer.
The world of personalized, on-demand manufacturing awaits. With some learning and experimentation, you’ll be on your way to printing incredible creations in no time!
