Here are the answers to the 3D Printing Quiz – Shhh, don’t share, and don’t cheat! 😉
01. This printer is a Cartesian style printer
02. 3D printing is an example of additive manufacture, material is added rather than taken away.
03. .OOP is NOT a common 3D printing file format
04. The 3D printing process starts with Computer Aided Design (CAD)
05. CNC (“Computer Numerical Control”) has a lot in common with 3D printers
06. This printer is an example of a Delta style printer
07. Benchy is popular because it helps people compare settings and calibrate their prints.
08. When you have horizontal skewing/waving layers of a print you would tighten belts.
09. You have a bad first layer. You would check your bed is level, tweak the z gap, and ensure your sensor is working (if you have one).
10. These lines around this calibration cube are called a Brim. A Brim is a Skirt with zero offset (it is attached to the model like the “brim” of a hat), so, in a way, a Brim is a subset of Skirt.
11. A clogged nozzle caused these prints to get progressively worse.
12. You need to occasionally grease your threaded rods/bushings/bearings.
13. On printers where you can not send the extruder to the very top of your z limit to level the X axis (as in the Prusa i3 Mk2), these types of pillars that you can print allow you to level the X by lowering the gantry until both sides touch the top of the pillars.
14. You would turn the thumb wheel (as looking at it here) counter-clockwise to increase the gap between the nozzle and the bed. Some thumb wheels have arrows or numbers to make this easier to check.
15. What is a Prusa? Prusa is both a printer AND a person (Josef Prusa, inventor of the Prusa printer)!
16. These supports dissolve in hot water.
17. The generic name for this material is TPU/TPE.
18. Which is the odd one out?
- Cura
- Slic3r
- Simplify3D
- Blender
19. Layer split! Increase hot end temperature
20. To remove this blob of PLA you would start by heating up the nozzle and gently scraping the plastic as it softens.
21. If this just started happening, check your belts are tight and your frame is still rigid. If it continues, test the extrusion is consistent. Acceleration and jerk problems usually manifest in vertical/corner rather than horizontal aberrations.
How did you fare? Which did you get wrong/correct? 🙂
