What is “3D Printer”?

3D printer is a device that creates three-dimensional objects by stacking materials like resin or metal, based on digital 3D data. Unlike traditional printers that deal with 2D data, these bad boys let you freely craft shapes in three dimensions.

3D printing is a groundbreaking technology that manufactures objects layer by layer from a digital 3D model. It’s paving the way in fields like design, medicine, education, and manufacturing, offering faster, more cost-effective, and flexible production compared to traditional methods.

Types of 3D Printers

There’s a whole world of 3D printers out there, each with its own specialty. Some of the heavy hitters include:

FDM (Fused Deposition Modeling)

FDM is the go-to for user-friendliness in 3D printing. It works by melting thermoplastic filament and laying it down layer by layer to shape an object. Great for prototypes or just tinkering around.


This technique uses light to harden liquid resin into highly accurate and smooth-surfaced objects. It’s perfect when you need to nail those intricate details, like in jewelry or dental work.

SLS (Selective Laser Sintering)

SLS uses lasers to sinter powdered material, layer by layer, creating objects without needing support structures. It’s a hit for complex geometries, widely used in engineering and aerospace.

Practical Uses of 3D Printers

With advancements in 3D printer performance and materials, these machines are revolutionizing manufacturing processes. Here’s what they can do:


In the design and development stage, 3D printers can whip up prototypes without molds, quickly and cost-effectively. This slashes development time, speeding up the journey to market.

Design Verification

At the planning stage, 3D-printed models can effectively share the final product’s vision, offering a more compelling presentation than traditional specs or illustrations.

Molds and Tooling

Traditionally, creating molds for processes like injection molding was both time-consuming and pricey. 3D printing offers a faster, cheaper alternative, especially beneficial during the prototyping phase.

Custom Tools and Jigs

As products diversify, so does the need for specialized tools and jigs. 3D printers can rapidly produce these custom solutions, enhancing productivity.

Construction and Architectural Models

3D printers play a crucial role in architecture, allowing for the quick creation of detailed models. This not only aids client presentations but also facilitates internal reviews and method planning.

Final Products

Directly producing final products like custom orders, small batches, or replacement parts is a breeze with 3D printing. This eliminates the need for traditional mold-making, cutting costs and reducing lead times.

Advantages of 3D Printers

3D printers offer several advantages:

  1. Quick Turnaround: Significantly faster than traditional prototyping methods.
  2. Cost-Effective: More affordable than conventional approaches.
  3. Complex Shapes: Capable of creating intricate designs.
  4. Design Freedom: High design flexibility.

Disadvantages of 3D Printers

However, there are some drawbacks:

  1. Accuracy: Might not match traditional manufacturing methods.
  2. Material Limitations: Restricted material options.
  3. Cost: High-performance models can be pricey.

How to Choose a 3D Printer?

When selecting a 3D printer, consider the following:

  • Purpose: What you’ll be using the 3D printer for.
  • Budget: How much you’re willing to spend.
  • Precision: The level of detail and accuracy you need.
  • Printing Speed: How fast you need the printer to produce models.
  • Material: The type of materials you want to use.

Choosing a 3D printer involves carefully evaluating your budget, required precision, print size, and the types of materials you plan to use. It’s also important to consider potential future upgrades.

The Future of 3D Printing

The outlook for 3D printing technology is broad and promising, with expected breakthroughs and progress in various aspects. Here are some potential developments:

Technological Advancements and Increased Precision
