Report 7 - 3D Printing

Q1: What is the basic principle behind 3D printing?

3D printing is an additive manufacturing process that builds objects layer by layer from a digital model.

Q2: What software is used to create 3D models for printing?

Computer-Aided Design (CAD) software is used to create virtual 3D models.

Q3: How is a 3D model prepared for printing?

The model is sliced into horizontal cross-sections using software, which are then sent to the printer.

Q4: What are common methods used in 3D printing?

Methods include melting plastic filament through a heated nozzle, curing resin with UV light, and fusing metal powder with a laser.

Q5: How do layers bond during the printing process?

Each layer adheres to the one below it, forming a solid structure.

Q6: What materials are typically used in recreational 3D printing?

Desktop printers often use plastic materials like PLA.

Q7: What materials are used in industrial 3D printing?

Industrial printers use high-precision materials such as carbon fiber, nylon, and metal.

Q8: How does 3D printing differ between recreational and manufacturing contexts?

Recreational printing uses simpler machines and materials, while manufacturing involves large-scale production with industrial-grade equipment.

Q9: How does 3D printing benefit individuals?

It allows people to create customized items like decor, jewelry, and gadgets at home.

Q10: What impact does 3D printing have on organizational supply chains?

It increases flexibility, lowers costs, and reduces lead times.

Q11: How does 3D printing support product innovation?

Organizations can experiment with designs and quickly adjust production to bring new products to market.

Q12: What is the societal value of 3D printing?

It drives innovation and enables more efficient processes across various sectors.

Q13: How does 3D printing contribute to healthcare?

It enables the creation of affordable medical devices, prosthetics, and tools.

Q14: What is a cost-saving example of 3D printing in healthcare?

A prosthetic hand that typically costs $25,000 can be 3D printed for around $250.

Q15: How does 3D printing benefit manufacturing?

It allows for on-demand production of custom parts, reducing waste and speeding up production.

Q16: What role does 3D printing play in education?

It enhances learning through engaging tools and helps teachers create cost-effective learning aids.

Q17: How much can educators save using 3D printing?

Michigan Technology University estimates savings of up to 86% on teaching aids.

Q18: Why is early exposure to 3D printing important for students?

It prepares them to thrive in a future where 3D printing is commonplace.
