Quick Tips About FDM 3D Printing Materials

Postby 3dtech » Tue Sep 26, 2017 10:10 pm

Choosing the right type of material to print a given object is becoming increasingly difficult, as the 3D printing market sees the regular emergence of radically new materials. In FDM 3D printing, PLA and ABS have historically been the two main polymers used, but their initial dominance was mostly fortuitous, so there should not be any major road blocks for other polymers to play a key role in the future of FDM.

Materials are usually graded along following categories

Ease of printing: How easy it is to print a material: bed adhesion, max printing speed, frequency of failed prints, flow accuracy, ease to feed into the printer etc.
Visual quality: How good the finished object looks. More info on how we test it here.
Max stress: Maximum stress the object can undergo before breaking when slowly pulling on it.
Elongation at break: Maximum length the object has been stretched before breaking.
Impact resistance: Energy needed to break an object with a sudden impact. 3d printing services in vapi gujarat

Fused Deposition Modeling (FDM)




Polylactic Acid (PLA)

PLA is the easiest polymer to print and provides good visual quality. It is very rigid and actually quite strong, but is very brittle.

Acrylonitrile butadiene styrene (ABS)

ABS is usually picked over PLA when higher temperature resistance and higher toughness is required.


Polymide (Nylon)

Nylon possesses great mechanical properties, and in particular, the best impact resistance for a non-flexible filament. Layer adhesion can be an issue, however.

TPU

TPU is mostly used for flexible applications, but its very high impact resistance can open for other applications.



Polycarbonate (PC)

PC is the strongest material of all, and can be an interesting alternative to ABS as the properties are quite similar.



Alloy 910

Polyvinyl Alcohol Plastic (PVA)


Apart from all these materials others materials are also used for 3D printing. Such as titanium, stainless steel, bronze, brass, silver, gold, ceramics, chocolate, bio ink, bone material, Objet Digital Material, Objet Tango Family, hot glue, glass, full color sandstone and gypsum.


The nature of material changes with the requirement of the model. So, there is a wide array of materials from which the most appropriate material is to be chosen. 3d printing in Andhra Pradesh, Karnataka, Kerala and Tamil Nadu,india,chennai,bengaluru,kolkata,lucknow,kanpur,india
