What material is used to 3D print products?

What material is used to 3D print products?

ABS (Acrylonitrile Butadiene Styrene) is a thermoplastic that is commonly used as a 3D printer filament. It is also a material generally used in personal or household 3D printing and is a go-to material for most 3D printers.

Which of the standards is used for tensile testing of AM generated parts?

The standards are ASTM D638 (tensile strength, elongation at break, modulus of elasticity) [44], ASTM D790 (flexural strength, flexural modulus) [45], ASTM D256 (Izod Notched Impact) [46], and various hardness scales.

Which standard is followed globally for testing materials for 3D printing?

The International Organization for Standardization (ISO) and ASTM International have jointly crafted the Additive Manufacturing Standards Development Structure, a framework which will help meet the needs for new technical standards in this fast-growing field.

What tensile strength means?

Tensile strength, maximum load that a material can support without fracture when being stretched, divided by the original cross-sectional area of the material. When stresses less than the tensile strength are removed, a material returns either completely or partially to its original shape and size.

Is 3D printed material strong?

3D printed parts are very strong, especially when using specialized filament like PEEK or Polycarbonate, which is used for bullet-proof glass and riot shields. Infill density, wall thickness and print orientation can be adjusted to increase strength. There’s a lot that goes into the strength of a 3D part.

How are materials tested for 3D printed plastics?

Materials testing of 3D printed plastics deposition modeling (FDM). Mechanical engineering d esign analyze, procure, and manufacture. This is, in part, due to the thermoset plastics can be approximated a s isotrop ic. However, with a more material efficient, structural lattice known a s infill. invalidates simulation results.

What kind of corrosive agent is used in 3D printing?

The corrosive agent chosen was Nitro-P, which is used to dilute paints and is very aggressive. To maximize the damage, the 3D printed parts were immersed in the solvent for a period of 24 hours, and their change in shape and properties was monitored by a timelapse camera followed by a visual and physical evaluation.

How are 3D printed parts tested under bending?

Doing some more research on testing done by others I determined that linear 1:1 scaling estimates work well with tensile stress, but not with bending. What I mean to say is that under tensile stress a part with 50% infill will be 50% as strong as that part with 100% infill. BUT under bending stress that same part will be more than 50% as strong.

How to 3D print ABS filament for mechanical testing?

All specimens were 3D printed on my FDM type Reprap PrintrBot, using Slic3r and Repetier Host software. All specimens were made of ABS filament from the same roll. All tests were run in a static 4 point bend configuration using TestrBot.
