3D printing Flashcards
What is 3D printing?
3D printing, also known as additive manufacturing, is a process that creates objects from computer-aided design (CAD) files by joining materials layer by layer.
What are the four main steps in 3D printing?
- Modeling: Creating a digital 3D model using CAD software.
- Slicing: Converting the model into layers using slicing software.
- Printing: The 3D printer deposits materials layer by layer.
- Post-processing: Refining the printed object, such as sanding and assembling parts.
What are common materials used in 3D printing?
Plastic filament (e.g., PLA, ABS)
Resin
Metal
Biodegradable materials
How does 3D printing benefit individuals?
It allows creativity, customization, and rapid prototyping, enabling users to create home decor, personalized gifts, and replacement parts.
How does 3D printing benefit organizations?
It reduces costs and time for prototyping, facilitates innovation, and supports sustainable practices through material recycling.
How does 3D printing benefit society?
Promotes sustainability by reducing waste and using recycled materials.
Enables on-demand production.
Supports industries like healthcare and aerospace.
What are examples of 3D printing applications?
Aviation: GE Aviation uses 3D printing for fuel nozzles, reducing weight and increasing durability.
Footwear: Adidas partners with Carbon to create customized midsoles using 3D printing.
What are alternative manufacturing technologies to 3D printing?
CNC Machining: Uses programmed tools for precision cutting and shaping.
Injection Molding: Injects plastic into molds for mass production.
In which industries is 3D printing highly suitable?
Aerospace: Used for lightweight, high-strength components.
Automotive: Reduces product development cycles and allows easy customization.
Healthcare: Produces implants, prosthetics, and surgical tools tailored to patients.
What are the limitations of 3D printing?
High cost: More expensive for large-scale production than traditional methods.
Supply chain integration challenges: Industries rely on centralized mass production, while 3D printing supports decentralized, on-demand manufacturing.
What are ethical and security concerns in 3D printing?
Intellectual property risks: Designs can be copied without authorization.
Cybersecurity threats: Hackers can alter digital designs.
Ghost guns: Untraceable 3D-printed firearms are difficult to regulate.
What are the key steps for implementing 3D printing in an organization?
- Management assessment: Determine business areas affected.
- Technical analysis: Evaluate IT resource needs.
- Operational analysis: Train employees for system interaction.
- Economic analysis: Assess financial viability.
- System analysis and design: Define parameters and restructure operations.
- Testing and phased rollout: Start with simple components before scaling up.
What challenges arise when implementing 3D printing?
Resistance to change: Employees may struggle to adapt to digital manufacturing.
Supply chain disruptions: Different materials are required for 3D printing.
Technology limitations: Not all complex manufacturing needs can be met immediately.
What are the three most common types of 3D printing?
- Fused Deposition Modeling (FDM): Melts and extrudes thermoplastic filament.
- Stereolithography (SLA): Uses a laser to cure liquid resin.
- Selective Laser Sintering (SLS): Uses a laser to fuse thermoplastic powder.
How does 3D printing impact industry competition?
Low entry barriers: Open-source designs and expired patents enable new startups.
Supplier power: Limited high-quality material suppliers have pricing control.
Threat of substitutes: Traditional manufacturing is still more cost-effective for large-scale production.
