3D Printing - "It's all about design and quality output. Not how fast the printer can run."
Low Cost 3D Printers
This is just my observation and experience. I am not promoting any particular brand of 3D printer. User experience depends on, well… user experience and the ability to recognize problems and make corrections. Mostly an ability to realize that about half of all beginner 3D printer “problems” are self-inflicted by the users lack of experience and inability to admit or realize their own mistakes. A tool is only as good as the user.
I purchased a Kilo of dark brown PLA with the brand name of AMZ3D. I have no idea who they are, but the product is clearly marked as “Made in China”. Someone in China is running this product on their line. I don’t have any problem with that.
It is obviously a brand created for Amazon. The AMZ in the brand name is the first clue. I did a web search and everything I found indicates it is an Amazon branded product.
One of the critical parts in a FFF 3D printer is the extrusion nozzle. It's that part that lays the rubber on the road. The exact flow of plastic is determined by temperature which affects viscosity, filament feed rate which is pressure, filament size which is volume. Put those factors through an orifice of a specific size (which then is a metering device), the exact flow can be calculated. The nozzle is the orifice but it also determines the initial diameter of the extruded plastic.
A little project at the request of my spouse. She was admiring my 3D printed holders for my wax carving tools and files. However, the holes were too small for the things she wanted to hold. I was tasked with creating holders with larger holes.
The first one was using three holes with a hole design diameter of 12mm. I “project named” it the TriHolder. A square sided cube wouldn’t be aesthetic so I created some curves on two sides. They widen the base and make it look a bit better.
This print is for my daughter. I made the green Yoda for her twin brother, so I needed to balance my generosity! Ha! Vause is the fancy word for a cheap plastic vase...
It’s another design I gathered from Thingiverse. This one is in the form of an SCAD file. That is a CAD drawing program that has parameters which can be changed or altered to create variations of a design.
