3D printing is a transformative technology that creates a paradigm shift in the manufacturing and design sectors. The pros of 3D printed parts include consideration in choosing the suitability of the technology for several reasons. However, it is essential to know how these individuals are strong enough and which factors support their robustness.
Furthermore, This blog will give you a brief on 3D printed parts on which basis the durability of parts and how to line up edges of 3d printer parts.
Manufacturing and Design Sectors
What is 3D printing?
3D printing is a process that transforms a digital 3D model into a physical object. Designers create this model using Computer-Aided Design or by using a 3D scanner to recreate an existing object. Once the designers finalize the 3D model, they slice it into several parts using special software, which thousands of individuals utilize for printing. These layers are then fed to a 3D printer which reads and prints them layer by layer using material of choice. Additionally, the materials might be plastics, resin ceramic or even metal which depends completely on the type of 3D printer used.
Types of Material Used in 3D Printing
There are several choices in choosing the material for your 3D printing. Several materials used in 3D printing each have their own strength, durability and weaknesses.
Starting off with,
Plastic: It is the most common material used in 3D printing mostly, when in FDM. The most common material includes ABS and PLA. ABS is known for its properties of strength, flexibility and temperature resistance. Whereas, PLA is rigid and brittle but is popular due to its lower melting point making it easier to print. Moreover, it is biodegradable in nature.
Polymers: They are mostly used in the SLA and DLP process of making 3D printing parts. These parts are known for their high resolution and smooth surface. Many people frequently use them in 3D printing because they are cost-effective, convenient, and versatile. Additionally, manufacturers often choose polymers due to their affordability and ease of use. However, they might be more brittle than plastic in FDM. Moreover, polymer chemical makeup and degree of curing all affect the mechanical, physical and chemical characteristics.
Metals: It is used in more advanced 3D printing like in DMLA and SLM methods. Metal 3D printing methods produce parts with strength and durability comparable to traditional manufactured metals. However, due to its rigid and durable parameters, the 3D printer does require specialised hardened steel nozzles. Moreover, commonly used metals include steel, titanium and aluminium with their own properties. It has several applications like aerospace, engineering and medicine.

Understanding the Strength of 3D-printed Parts
The strength of 3D printer parts is influenced by several factors. It is not solely focused on materials but also on processes like printing, design of the part, and post-printing process. However, you should know the strength of 3D printing is the ability of the printer to withstand forces or stress without deforming.
Material selection: As briefed in the above section on how particular materials reflect or exhibit their properties. Different materials have different properties like strength, flexibility and hardness. For example: PLA materials can take up to 66MPa whereas, the structural stiffness of titanium alloy is up to 659 MPa.
Printing parameters: Layer height like infill density, print speed and temperature have a substantial effect on the part’s strength. For example, higher infill densities increase the strength but also increase print time as well as material usage. It usually plays a key role in analysing the stretch because the layers have better adhesion properties to each other.
Part design: The design of the material which needs to be printed plays a key role in estimating the strength. Like the geometry orientation and the ability of the printer to withstand stress. Experts generally recommend conducting a CAE test on the part or assembly to understand the forces and deformations that the subject might experience under the stress of applications.
Conclusion
In conclusion, 3D printed parts compared to traditionally manufactured parts sometimes tend to be a topic of interest in the manufacturing sectors. However, 3D printing has its own pros and cons.
