Are you thinking about buying a 3D printer? With the holidays around the corner, you might be considering a new machine for yourself or someone special. But with so many options and price points, selecting the right 3D printer can feel overwhelming. This guide walks you through 11 essential steps to help you make the best choice.
Step 1: Don’t Rush into Buying a 3D Printer
It may seem odd, but don’t rush to buy a 3D printer right away! Take some time to learn CAD (Computer-Aided Design) applications, which will allow you to create digital models and get the most out of your future printer. Here are three ways to gain experience without the initial investment:
- Ask a friend with a 3D printer to print a few models for you.
- Visit a local makerspace to try out their 3D printers. Makerspaces often have equipment available for a small fee.
- Use a print-on-demand service, like Shapeways, to upload your files, select materials, and receive your printed object by mail.
Step 2: Set a Budget
3D printers range from a few hundred to tens of thousands of dollars. Decide your budget early to avoid overspending. Be realistic about what you can afford without compromising on the quality you need.
Step 3: Identify Your Intended Use
Different printers and technologies suit different types of projects. The two most common types are:
- Fused Deposition Modeling (FDM): Uses filament and builds models layer by layer. Great for hobbyists, with a wide range of materials available.
- Stereolithography (SLA): Uses resin and light to create highly detailed prints. Perfect for intricate designs but has a smaller build volume and requires careful handling.
Decide whether you’ll be printing small models or larger, multi-part objects, as this will impact your choice.
Step 4: Choose Your Material
3D printers can work with many materials, each with its own pros and cons. Common materials include:
- PLA: Easy for beginners and suitable for many projects.
- Composite materials: More advanced and abrasive, so you may need upgrades like a wear-resistant nozzle.
- Flexible materials: Like TPU, which requires a direct-drive printer for better control.
Choose a printer that’s compatible with the materials you intend to use.
Step 5: Consider Your Space
Think about where you’ll place the printer. Keep in mind:
- Noise: Printers can be loud, so consider your neighbors if you live in an apartment.
- Ventilation: Resin printers, in particular, release fumes and need a well-ventilated space.
- Size: Larger printers take up more space and may not fit everywhere.
Step 6: Decide Between DIY, Kit, or Turnkey Printer
You can buy a printer that’s:
- Scratch-built: Assemble every part yourself (best for experienced users).
- Kit-based: Comes with all components and instructions, requiring some assembly.
- Turnkey: Fully assembled and ready to use out of the box (ideal for beginners).
Each option has advantages in terms of price, setup, and support.
Step 7: Create a Shortlist
List three to five printers that meet your needs. Research each one’s features, build volume, and compatibility with your preferred materials.
Step 8: Do Your Homework
Read reviews and gather feedback on each printer from other users. Pay attention to both positive and negative comments, especially around reliability, support, and print quality.
Step 9: Find a Reputable Supplier
Choosing a local supplier can simplify repairs and returns if issues arise. If buying internationally, be prepared to manage potential support challenges or costs.
Step 10: Find a Material Supplier
Explore different brands and suppliers of filament or resin. Experiment with different options until you find a reliable brand that works well with your printer.
Step 11: Join Online Support Groups
Joining online forums or social media groups can provide valuable insights and troubleshooting tips. Users in these groups often share modifications, settings, and advice on making the most of specific printers.
Top Brands for Different Needs
If you’re still unsure, here are some popular brands:
- Prusa: Offers high-quality kits, ideal for those comfortable with assembly.
- Creality: Known for part-assembled kits, like the CR-10 series, which are beginner-friendly and easy to set up.
- Ultimaker: Premium turnkey solutions, offering reliable, high-quality machines across multiple sizes.
By following these 11 steps, you’ll have a clear understanding of what you’re looking for and feel confident in selecting the right 3D printer.
