anyone have experience with a "Tina2". It is a smaller, cheapy unit that I saw on utube. looks interesting and funner as a starter machine but I am skeptical due to the "you get what you pay for" theory.





Welcome to the wonderful world of plastic design. I follow the same rules that I learned doing injection molded part design. Including fit tolerances. 3D printing introduces another set of criteria into the mix.Note the file name "Vaccum cord winder v18" and no not that I misspelled Vacuum but v18, yes 18 versions to get it close to the original.


I'll start with a few questions.OK
I have been sifting through the 3d printer market and frankly, it would be easier to throw a dart.
I try to do research but the manufactures make it hard to determine what the difference between models are. Then, go on Ebay and there several sellers that off "open box", used and returned (supposed works like new - with minimal warranty).
So, what are desirable features to look for, for a guy who is mechanical /electrical / computer/ CAD savvy? What accessories are a must have? What consumable materials are most widely used? Good brands? Emerging brands?
I know, all are loaded questions.
Bottom line, I would prefer a moderate size envelope, good precision and price under $350?
parts to support other "hobbies"What do you want to make with a 3d printer?
My expectations will be a machine that requires "finesse", preparation and fore-thought to make parts with some degree of precision. I'm not expecting tenths or even thousandths but good replication of a generated model.What are your expectations from the printer?
a tool that, in itself, a hobby. Most of my hobbies interweave at some point. Kind of the thought " we create tools to create better tools".Is the printer the hobby or a tool for your hobbies?
Great. I just added to my previous pot.parts to support other "hobbies"

As others have said, a lot depends on what you will print on it.Are there particular features that are a necessity? Self leveling seems a must. Direct drive vs Bowden?
Ah...Welcome to the rabbit hole. This is what happened to me. Started simple and kept adding features. My budget started at $160 and jumped to $1k. Do I regret it? No. My printer is reliable and I don't have to mess with it. (Much.)one model had a print envelop of 210x210x250 for a reasonable price and the next model in that series had an envelop of 300x300x350 - for $50 more. I would buy the bigger model.
I would get opt for direct drive over Bowden. Self leveling is nice but I don't see it as a necessity. My machine doesn't have it, I don't level my machine very often. I do a quick level when I remove the print head or change the nozzle.Are there particular features that are a necessity? Self leveling seems a must. Direct drive vs Bowden?
Those 200hrs weren't wasted, you've now learned the basics of how to model parts, so the next widget you need to make might only take you a few hours. Nice workA recap, to save $7 plus $10 shipping I invested ~200 hours and wasted $5 in filament printing failures. But now I feel good about playing more and being able to produce something in Fusion 360. I'm not a professional by any means but where I was once reliant on using things others created I can at least modify what they have done or if I feel inclined can try making it myself.
Ditto (more or less) with my Ender 3 Max Neo. Maybe the fiddling comes in with tougher to print resins, but PLA has been pretty easy and successful. I've only had 2 real issues that I've ran into that weren't a result of a stupid modelling or slicing error on my part:I've had an ender 3 pro and I don't know what all this constant fiddling talk is, but I must have hit the jackpot because after the initial setup it's been rock solid.
QFTUnless you already know your way around fusion 360 or similar programs & Cura or other slicers I think you will spend way more time fiddling there, then you ever will with the printer. The printer will become the very simple part of the puzzle quickly.
Once you become proficient with CAD, you'll have a whole new world available with 3D printing. Need a little piece of trim that's NLA? No problem. Need a custom dust collection adapter? No Problem. Need a custom tool? No problemQFT
This all day long but there are so many STL files out there to use until you are ready to dive into that. I was content for a little while just printing things others had made STL files for but have been aware of CAD for a long time. Just never could justify the time to invest in learning until the vacuum part broke that I made. Now, it's just another tool in the toolbox that I can bring to the table. Seeing that throttle body adapter above make me want to print a carb spacer for my car.
It always takes a project to start.Just never could justify the time to invest in learning until the vacuum part broke that I made.
It's tough when you know a program to move to another. I use FormZ, Rhino, Zbrush, and VisualCAD/CAM. I used AutoCAD, Inventor, Revit and Solidworks before I retired. Rhino has a trial version but it still costs about $900. FormZ has a free version. Since I no longer have to follow any standards. I'm most comfortable in FormZ and Zbrush.I have explored other Cad packages trying to get back to the freindliness of Inventor.
Agreed, my experience is the same as well. I think people sometimes have a preconceived notion in their mind, or are loyal to a brand and don't consider other opinions. Same folks keep Snap-On in business as well.I've had an ender 3 pro and I don't know what all this constant fiddling talk is, but I must have hit the jackpot because after the initial setup it's been rock solid.
