What are the most common materials used for 3D printing?
« on: August 14, 2017, 12:00:08 pm »
Most materials currently used in 3D printing are plastics.all print in a thermoplastic called ABS, using a process called Fused Deposition Modeling (FDM).

following are Most Popular 3d printing materials used

Polylactic Acid (PLA). This versatile and relatively low cost printing material that is readily available and can be used for many articles. Itís not the strongest of the printing polymers available but is extremely useful depending upon your application. It is derived from corn starch and is therefore biodegradable over time. PLA shapes find great use as removable shape used in modern investment casting processes. The finished, printed shape is coated in a ceramic film before being burnt out and the resulting void filled with molten metal to form the proper part.

Acrylonitrile Butadiene Styrene (ABS). This is a tough material that can be used to create finished parts that will put up with the rigours of everyday use. Slightly problematic if the feedstock is kept in a humid area, ABS works best when thoroughly dry. As with all thermoplastics, filaments are available in a range of colours.

High Impact Polystyrene (HIPS). This is s a tough durable material akin to ABS though not the cheapest option. HIPS uses Limonene as a solvent which tends to make the finished part smell slightly of lemons, but thatís not all bad is it. The heater element of the printer needs to be controlled quite finely with this material otherwise there will be a fair degree of warping as the hot material is placed on the cooling layer, but with smaller parts (which youíll probably want to do anyway since itís an expensive base material) the speed of printing should be just fine to prevent warpage.

ninjaflex filament - flexible 3d printing

 3d printing with pva - polyvinyl alcohol Ė This is used as a dissolvable support material or for special applications.

 printing on polycarbonate (PC) Ė Polycarbonate requires high-temperature nozzle design and is in the proof-of-concept stage.
    SOFT PLA - polylactic acid Ė Is rubbery and flexible, available in limited colors and sources. As 3D printing spreads, may get easy to find.
