MSBTE Practical Viva/Oral Questions and Answers

1. What is 3D printing?
Answer: 3D printing is an additive manufacturing process that builds objects layer by layer from digital models.

2. What is additive manufacturing?
Answer: It is a process of creating objects by adding material, unlike traditional subtractive methods.

3. Name types of 3D printers.
Answer: FDM (Fused Deposition Modeling), SLA (Stereolithography), SLS (Selective Laser Sintering).

4. What is slicing in 3D printing?
Answer: Converting a 3D model into layers and generating printer instructions (G-code).

5. What is CAD software?
Answer: Computer-Aided Design software used to create digital models for 3D printing.

6. What is filament?
Answer: Material used in 3D printing, such as PLA, ABS, or resin.

7. What is bed leveling?
Answer: Adjusting the printer bed to ensure the first layer sticks properly.

8. What is nozzle temperature?
Answer: The temperature at which filament melts for extrusion in FDM printers.

9. What is print resolution?
Answer: Layer height determining the detail and smoothness of printed objects.

10. What is infill in 3D printing?
Answer: Internal structure of a print providing strength without using excess material.

11. What is support material?
Answer: Temporary structures printed to support overhangs in complex models.

12. What is post-processing?
Answer: Techniques like sanding, polishing, and curing to improve print finish.

13. What is warping?
Answer: Deformation caused by uneven cooling of printed layers.

14. What is stringing?
Answer: Thin filament threads left between parts of a model due to oozing.

15. What is G-code?
Answer: Instructions sent to the 3D printer to control movement and extrusion.

16. What is layer adhesion?
Answer: Strength between consecutive layers of a 3D print.

17. What is PLA filament?
Answer: Polylactic Acid, a biodegradable and easy-to-print material.

18. What is ABS filament?
Answer: Acrylonitrile Butadiene Styrene, strong and heat-resistant plastic.

19. What is SLA printing?
Answer: Using a laser to cure liquid resin layer by layer.

20. What is SLS printing?
Answer: Using a laser to sinter powdered material into solid objects.

21. What is overhang in 3D printing?
Answer: Part of a model that extends beyond the layer below without support.

22. What is a raft in 3D printing?
Answer: A base layer printed under the model to improve adhesion.

23. What is infill density?
Answer: Percentage of material used to fill the interior of a print.

24. What is a heated bed?
Answer: A printer bed that heats to prevent warping and improve adhesion.

25. What is nozzle diameter?
Answer: Size of the printer nozzle that affects extrusion and detail.

26. What is 3D print speed?
Answer: Rate at which the printer moves while extruding filament.

27. What is a slicer software?
Answer: Software that converts 3D models into layer instructions for printing.

28. What is over-extrusion?
Answer: Printing too much filament, causing blobs or rough surfaces.

29. What is under-extrusion?
Answer: Printing too little filament, causing gaps or weak layers.

30. What precautions are necessary in 3D printing labs?
Answer: Avoid touching hot surfaces, handle resin safely, maintain clean beds, and check printer calibration before printing.
