Default What are the materials &resins mostly used for 3D printing?

On the desktop it is mainly PLA followed by ABS. Nylon. Other materials such as Colorfabs Bronzefill are becoming popular. 3d printing materials used

Stereolithography (SLA) resins are popular in prototyping and mold making. These photopolymers are also used for Objet, Envisiontec and Formlabs systems.

In terms of raw materials that are put into the printing system to create the 3-D objects, there seem to be relatively few limitations on what can be used.

Currently, plastics are the most widely used materials in additive manufacturing, and the important ones are listed below: 3d printing in mumbai pune maharashtra india




FDM Materials

taulman alloy 910 nylon

ABS - acrylonitile butadiene styrene or 'lego' plastic – a very common choice for 3D printing
3d printing pla - polylactic acid – Is available in soft and hard grades, is becoming very popular and may overtake ABS in the near future
3d printing with pva - polyvinyl alcohol – This is used as a dissolvable support material or for special applications.
printing on polycarbonate (PC) – Polycarbonate requires high-temperature nozzle design and is in the proof-of-concept stage.
SOFT PLA - polylactic acid – Is rubbery and flexible, available in limited colors and sources. As 3D printing spreads, may get easy to find.

SLA Resins

General Purpose Resins
To start, there are a number of firms producing 3D printing resins for desktop machines. Though many 3D printer manufacturers sell their proprietary materials, several generic brands have taken to making their own varieties for these systems, including MadeSolid, MakerJuice and Spot-A Materials.


Tough Resins
Typically photopolymer resins used for 3D printing on desktop machines are somewhat fragile, leaving those delicate details susceptible to snapping and cracking. For this reason, the technology has been used more frequently for aesthetic purposes, such as artistic models and visual prototypes. To address these issues, numerous companies have begun producing tougher and more durable resins.

Castable Resins


Casting has long been a process supported by photopolymerization technologies, with industrial manufacturers often marketing SLA and DLP machines to the dental and jewelry markets for the ability to fabricate parts that can be cast as metal. Naturally, producers of resins for desktop machines began with low-cost casting resins.



Flexible Resins

There are a limited number of manufacturers of flexible resins, including Formlabs, FSL3D and Spot-A Materials, all of which make a material for printing rubbery parts. This is ideal for prototyping elastic products, such as water bottles, handles and grips. Careful not to stretch too much or these components might tear!

High-Temp Resins
Formlabs, however, is so far the only low-cost manufacturer to produce a resin that can withstand high temperatures. The material has a heat deflection temperature (HDT) of 289 °C (552 °F) at a loading of 0.45 MPa , which is not just good for desktop SLA, but for all 3D printing photopolymers, including industrial systems. It can therefore be used for such applications as producing injection molding tools, testing channels designed for hot air or fluids and creating tools for thermoforming and casting.

Ceramic Resins
Tethon3D is a materials company focused on ceramics for 3D printing, first creating its own ceramics material for 3D Systems' binder jetting 3D printers. The Nebraska-based company then launched a crowdfunding campaign for a resin called Porcelite.

Open-Source Resins

It's a bit unclear how many folks are purchasing or building Autodesk's open-source Ember 3D printer, but the software company deserves props for releasing the complete designs for its DLP machine. More than that, Autodesk actually opened up the recipe for its photopolymer resin as well. The company's standard clear resin can be developed at home or in a lab or modified to produce new materials.
