Hi, I building my “very own printer” and need some advice. I tested most of the nozzle available in the market, 0.3, 0.35 and 0.4mm, the extruded ABS or PLA diameter always larger then the spec nozzle diameter, 0.3mm, I am getting around 0.4, 0.35mm I am getting around 0.4~0.45mm. Can’t seem to get exact nozzle diameter. Any advice, is this normal? Can anyone help on this area?
By the way, I am using 1.75mm filament (PLA/ABS)
This is normal.
thermoplastics expand.after being compressed and heated.
Thanks, I building my own printer wanted to market it, if this is the case, how will I spec it? Does this mean the stated nozzles doesn’t print according to it dimension?
Thanks
You might want to reconsider trying to engineer, market and sell a 3D printer if you’re still lacking this kind of basic knowledge, @TB_Foong
@Thomas_Sanladerer he didn’t say anything about “market and sell”.
It’s perfectly normal for someone to build a printer from the ground up only for personal use.
@Marcus_Wolschon i’m all for building your own printers and learning in the process. In fact, that’s the exactly why i’m spening hundreds of hours helping people out and making videos on those topics. But i think we’ve all been sensitized for those kickstarters; and “wanted to market it, if this is the case, how will I spec it” does sound an awful lot like it’s headed straight for crowdfunding.
Yes, didn’t look at that comment.
Bad idea.
Thanks for the advice, I believe I do have a lot to learn. Don’t try you never know. I had 1 3D printer and I believe I can build better. The printer said or promise of wander, but issue one after another and finally broke down, that trigger me to dream of build at least one that is “acceptable” for a budget community, someone like me. Although I may not know a lot, I don’t think it need rocket science.
Truth be told, when I first met Brook from Printrbot, he wasn’t the most knowledgeable guy in the world on 3d printers. I honestly thought his kickstarter was a bad idea, and that the printer had some serious flaws. But you know what I noticed was his willingness to learn, iterate, and keep trying. You won’t get it right on your first try, and likely your second. Experience is built upon the failures. Knowledge is grown over time.
my advice is don’t rush things, make sure you have a solid product with a solid design.
lower your E setting
No. That is E step setting for your extruder. If your extruder step motor pushes more pressure , the filament may come out bigger than the desired diameter. Lower the setting may lower the pressure.
so the setting is “steps per mm” for the Axis “E” as opposed to X,Y,Z .
Yes, but that setting changes absolutely nothing about the die swell.
Even I who run 10 printers 24 hours a day will not dare to sell. There are lots of learning curve both for maker and users how to use this technology. It is not the same as you use ordinary printer. Not just click and the printer runs by itself.
