Physical properties of 3-d printed objects vs casted/milled objects

[rohit_krishna]

Hi Guys,
I am new the 3-D printing world. I want to research on the physical properties of materials produced by 3-D printing to that of traditional processes. Can anybody help me with any detailed information regarding this.

Thank you.

Hi Rohit,

I am sure there is a multitude of information on what you require.

Are you able to clarify what you need information on. I understand that you want to compare the materials used in 3D printing to the materials of traditional manufacturing processes?

If that is the case then I guess you would need to understand all the various types of filament available (and there are lots)

The most common are PLA and ABS which we sell. You might want to check out our website for a basic understanding?

However, PLA and ABS are just the tip of the iceberg. Check out here for a guide to some printable materials:

Also check out here: https://www.matterhackers.com/3d-pri...lament-compare

There are also many articles on more specific materials. For example, here is an article on wood filament:

For other filaments such as the increasingly common metal filaments check out here:

I hope some of the above helps and if you need more information then please ask.
You can also contact me directly if you want to via support@3dexfilament.com

Hi,
Thanks for your response.
I actually want to draw a comparison between traditional manufacturing process to that of 3d printing processes depending on the physical properties of the products.I wanted to know which process is giving a product with better results in terms of its tensile strength, roughness or other physical properties.

You may want to check out the use of 3D printing in Formula 1. Formula 1 teams have long been employing the use of casting and milling to make precision parts so many of the articles on 3D printing in F1 explain the reasons why it is used as a manufacturing process over casting or milling.

Below are some articles that might be a good place to start.

I hope some of this helps.

There are so many 3d printing styles and different types that I feel you need to create a much more specific question. There are FDM, SLS, SLA, Objet, Zcorp, DMLS, and many other additive manufacturing processes that all give you very different results.

Are you looking for 3D printed Plastic vs machined plastic vs formed plastic, or are you looking for 3D printed metal objects vs machined? I interviewed with a company that was 3D printing metal for Airplane Engine Turbine Blades and they claimed they were able to keep 100% of the structural properties while decreasing the weight. Because you cannot machine internal voids to a solid part w/o 3D printing. Their printer cost over 1mil USD.

Since you are not assembling any part the structure is more solid than if you assembled or welding the part, hence 3d printed object is indeed very well sturdy and strong!

I am looking for looking for 3D printed Plastic vs machined plastic vs formed plastic. I want to compare few crucial physical properties like Tensile strength, surface roughness etc of the product produced from a 3-d printing process to that of traditional casting/milling product.
