What Is a 3D Printer? Learning the Basics

How 3D Printers Work and Their Types

3D printers create physical objects by building them up layer by layer from digital data. This is called “additive manufacturing.” Common types of 3D printers include FDM (Fused Deposition Modeling), SLA (Stereolithography), and SLS (Selective Laser Sintering).

FDM extrudes heat-melted filament through a nozzle to build objects, while SLA uses a laser to cure liquid resin. SLS sinters powder materials with a laser and is used when robust parts are needed. When choosing between these technologies, consider your application, materials, precision, and cost requirements.

History and Evolution

3D printers emerged in the 1980s and have evolved rapidly since then. The first commercial 3D printer was invented by Charles Hull in 1986, using SLA technology. Since then, many companies have developed new technologies and higher-precision printers, and today they’re used across a wide range of fields including home use, industry, medicine, and education. In recent years, new materials like metals and carbon fiber have become commonplace, enabling even more diverse applications.

Key Applications of 3D Printers

3D printers have a wide range of applications including prototype creation, custom part manufacturing, education, and art production. Engineers use them to rapidly create prototypes to speed up product development. In the medical field, they’re used to create custom prosthetics and implants, as well as dental applications. Artists use 3D printers to bring their ideas to life as physical objects. Educational use is also growing, helping students deepen their understanding by creating physical models.

What 3D Printers Can and Can’t Make

Things that can be created with 3D printers include mechanical parts, prosthetics, prototypes, and figurines. However, not everything can be made. For example, parts requiring advanced mechanical properties, very large objects, or components that must be made from specific materials can be challenging for 3D printers. Complex shapes requiring support material or specific surface finishes may need additional processing.

Drawbacks and Limitations of 3D Printers

3D printers have several drawbacks and limitations. For example, slow build speeds make them unsuitable for large objects or mass production. There are also material constraints — not all materials can be used. Some filament types can be expensive or lack strength and heat resistance. Additionally, complex shapes with fine details require support material, making post-processing labor-intensive. It’s important to consider these factors when deciding how to use a 3D printer.

What You Need to Get Started with 3D Printing

Choosing Your First 3D Printer

When choosing your first 3D printer, consider your intended use, budget, space, and materials. For home hobby use, relatively affordable and easy-to-operate models are suitable, but if you need precision and features, consider a slightly more expensive industrial-grade printer. FDM, SLA, and SLS printers each have their pros and cons — FDM is easy to operate with cheap materials, while SLA offers high precision and is advantageous for complex shapes. Choose the printer that best suits your needs.

Peripherals and Tools Needed for 3D Printing

Using a 3D printer requires more than just the printer itself. You’ll need materials like filament and resin, a heated print bed, nozzle cleaners, tweezers, spatulas, and tools for removing support material. These tools are important for ensuring print quality and improving work efficiency. A filament holder, dryer, and IPA (isopropyl alcohol) for part cleaning are also useful additions.

Budget and Running Cost Considerations

When getting into 3D printing, consider not just the initial investment but also running costs. Initial costs include the printer itself, software licenses, and peripheral purchases. Running costs include filament and resin, annual maintenance, and consumable replacements. Special filaments and resins used with high-performance printers can be expensive, so costs can add up with frequent use. Carefully estimate your budget and running costs to ensure adequate funding.

How to Use a 3D Printer: Step by Step

Data Preparation and Print Settings

Proper data preparation is crucial for successful 3D printing. First, export your 3D data in STL format and load it into slicer software. The slicer divides the data into layers for building and configures settings for each frame. Fine-tune nozzle temperature, bed temperature, filament type, print speed, and other settings to optimize the build. You’ll also decide whether to use support material and rafts during this process. This is a critical step that affects the precision and durability of your printed objects.

Print Execution and Important Notes

Once settings are complete, it’s time to start printing. Key points to watch include verifying the print bed is level and ensuring filament is properly loaded. If the first layer doesn’t adhere well or filament gets clogged, address the issue promptly. Check progress frequently during printing and immediately pause if any abnormalities occur to investigate the cause. For long prints, prepare extra filament in advance to avoid running out mid-print.

Support Material Removal and Finishing

After printing is complete, you’ll need to remove support material and apply finishing touches. Carefully remove support material and polish surfaces to improve the finished quality. Tools include tweezers, spatulas, and sandpaper. In some cases, special solvents may be used to smooth edges. Painting or coating can improve appearance and enhance durability. Finishing is an important step for improving the quality of your completed pieces.

Troubleshooting Print Problems

Various problems can occur when using a 3D printer. For example, filament clogging or prints detaching from the bed. For clogged filament, clean the nozzle and load new filament. For bed adhesion issues, adjust bed temperature or adhesion properties. If initial print settings are inadequate, readjust settings in the slicer software. Acquiring basic knowledge and techniques for handling these problems is important.

Practical Project Ideas and Useful Items

Examples of useful items you can create with a 3D printer include stationery holders for the office, kitchen tools for home use, and gardening accessories. Popular items include custom-fit phone stands, cable management tools, and planters. These can be created with your own original designs that aren’t available commercially, making them highly appealing. The ability to create unique items at low cost is a major advantage of home 3D printers.
