WHAT IS 3D PRINTING ?
"3D printing: A computer-controlled additive manufacturing process that creates three-dimensional objects by depositing materials such as plastics, metals, ceramics, and others, layer by layer, according to a digital model or design, allowing for the production of complex geometries, structures, and products with high precision, accuracy, and customization."
The Evolution and Impact of 3D Printing :
3D printing, also known as additive manufacturing, is a revolutionary technology that enables the creation of three-dimensional objects from digital models. This process involves laying down successive layers of material until the final object is formed, providing immense versatility and precision. Since its inception in the 1980s, 3D printing has evolved significantly, impacting various industries and everyday life.
HISTOY OF 3D PRINTING :
The concept of 3D printing has been around since the 1960s, but it wasn't until the 1980s that the first 3D printing technologies were developed. In the 1990s and 2000s, 3D printing started to gain popularity, with the introduction of new technologies and materials
-
The first person created with this concept is the man Dr.GAO KODAMA.
-
Mid 1980's Charles Hull invented the process STEREO LITHOGRAPHY(SLA), a process that uses UV lasers to solidify photopolymer resin. This breakthrough marked the beginning of 3D printing technology.
-
In 1989, SCOTT CRUMP is best known for inventing Fused Deposition technology (FDT), a key innovation in 3D manufacturing processes worldwide.
HOE 3D PRINTING WORKS :
1.Design: A 3D model is created using computer-aided design (CAD) software or scanned from an existing object. 2.Slicing: The digital model is sliced into thin horizontal layers using specialized software. 3.Printing: The 3D printer reads the sliced file and lays down layers of material, one by one, to build the object. 4.Post-Processing: The printed object may require cleaning, curing, or additional finishing, such as painting or assembly.
MATERIALS USED IN 3D PRINTING
3D printing utilizes diverse materials like ► Thermoplastics (PLA, ABS) ➤ Metals (titanium, aluminum) ➤ Its constantly innovating with new options like carbon fiber composites and bio-inks.
Types of 3D Printing Technologies:
There are several 3D printing technologies, each suited for different applications:
- Fused Deposition Modeling (FDM): Uses thermoplastic filaments that are heated and extruded layer by layer.
- Stereolithography (SLA): Uses a UV laser to cure liquid resin into solid plastic.
- Selective Laser Sintering (SLS): Uses a laser to sinter powdered material, binding it together to create a solid structure.
- Digital Light Processing (DLP): Similar to SLA but uses a digital projector screen to flash a single image of each layer at once.
- Binder Jetting: Uses a liquid binding agent deposited onto a powder bed layer by layer.
