What is 3D Printer : Features & Top Manufacturer Companies
Advertisement
A 3D printer is an advanced manufacturing device that creates three dimensional objects by building material layer by layer from a digital design file. Key features of 3D printers include high precision, rapid prototyping, customization, reduced material waste and the ability to produce complex geometries. Leading 3D printer manufacturers include Stratasys, 3D Systems, Altem Technologies and Afinia, serving industries such as healthcare, aerospace, automotive and consumer products.
Traditional printers are not capable of producing 3-Dimensional (3D) prints. This limitation often requires more time and effort in designing and developing prototypes. Fortunately, 3D printers are now available, capable of printing 3D documents and pictures.
These printers accept .stl files and convert them into gcode files. The gcode files are then used to print the layers one by one, building the 3D object. 3D printers are invaluable for quickly checking mechanical designs and ensuring proper fitment.
In contrast to traditional printing processes where you need to wait for prototype films, 3D printing allows for immediate physical evaluation of designs.
There are two primary types of 3D printers:
- DIY (Do It Yourself): These kits require assembly using a manual.
- Assembled: These printers arrive ready-to-use, allowing you to start printing immediately.

3D Printer Selection Guide
Before purchasing a 3D printer, consider the following specifications:
- Maximum Print Size: The largest dimensions the printer can produce.
- Horizontal and Vertical Resolutions: The level of detail the printer can achieve.
- Print Speed: How quickly the printer can complete a print job.
- Number of Print Heads (Extruders): The number of different materials or colors the printer can use simultaneously.
- SD Card and Display Support: Allows for standalone printing without a computer connection.
An SD card allows the printer to store print files and operate continuously without needing a constant computer connection.
Carbon fiber materials are often used in 3D printers, typically in the form of composites, for their strength and lightweight properties.
