Q: What is 3D printing, and how does it work?

3D printing , also known as additive manufacturing , is a revolutionary process that constructs three-dimensional objects from digital files. Unlike traditional subtractive manufacturing (like CNC machining) which cuts away material, 3D printing builds objects layer by layer. The process begins with a 3D model created in CAD software. This digital model is then sliced into thin horizontal layers by slicing software. The 3D printer reads these slices and deposits material—be it plastic, resin, metal, or powder—layer upon layer until the physical object is formed. At Ultratec 3D , we leverage cutting-edge technologies to deliver superior results: HP Multi Jet Fusion (MJF): A powder-based technology that fuses material with agents and heat, producing functional nylon parts with high strength and fine detail. Color Jet Printing (CJP) : A binder jetting technology that creates full-color, photo-realistic models using a gypsum-based powder, perfect for architectural models and figurines. Stereolithography (SLA) : Uses a laser to cure liquid resin into hardened plastic, offering smooth surface finishes and high precision for intricate prototypes.
