Depends on the quality. My tube melted because I was printing petg (250°C) and it was a cheap nozzle. Got better tubing and haven't had an issue since.

PFTE should be able to survive into the 300°C range before reaching it's transition temperature. You might need to double check your supplier is giving you what you paid for.

HATE Recon how would you fix this
View attachment 261869 View attachment 261870
I know it has to do w/ extrusion but I dont know what to do to solve it. I was thinking of doing a cold pull on it but id rather avoid it
I had the same thing happen with my davinci jr. I dug up a tiny resistor and shoved a lead up the nozzle a few times and wiggled it around. Pretty much fixed the problem.

Not sure how your printer works, but the davinci jr has a few mm airgap in the extruder chassis between the bowden feed line and the heating element/nozzle (also a filament detection switch lives there, but its beside the point), so if your printer has a similar setup and is melting your tube across an air gap you might be pushing your luck with your temperature.

To help the forum with the vast world of 3D printing I am staring this thread to have ANY ONE ask and get answers .
got a bad failed print of a prop Hopefully with the fine folks on here we can help each other out.
And also help the new folks not repeat the stuff that does not work. NO point in wasting time and plastic on things that don't work.
ill be editing this top part to have links to the Q's and failures and links to solutions .





Some helpful Software for the steps of printing:

http://www.123dapp.com/ A set of programs made by AutoDesk. These are the folks who make some of the best CAD programs in the world.
Most useful is " Design " . It's as basic as MS paint but more then enough to get you in to the world of Mech CAD.
It Runs on both windows and mac OS'es.

The 123D Apps are free for personal and edu use! Commercial use is 10USD a month.

http://www.meshmixer.com/ Also from AutoDesk Meshmixer lets you scale ,Dice and work with STL's and OBJ's,
With MM you can fit props to your print bed and find flaws. Remove and add polys, And use it as a means to add some shaders to visualize your project.
Runs on both windows and mac OS'es.


blender.org - Home of the Blender project - Free and Open 3D Creation Software Blender is VERY powerful. While not really a true Mech CAD program,
It's vast tool array for working with pre made assets makes it a great tool to use for the Mesh to Solid conversion that is the cornerstone of 3D printing .
Blender also does a very good job with poly Up conversion to take a raw asset and let you make then worth printing.
It runs on *Nix Windows and mac OS'es.
There are 3Dprinting plug-ins for Blender but I've yet to use them.

Additive Manufacturing and Design Software | Netfabb | Autodesk Netfabb is the industry standard for repair of soon to be printed models.
Got a hole in a print Netfabb Will fix that!
Here is the version you will wanna download .
https://www.netfabb.com/blog/netfabb-basic-now-just-netfabb
Sadly its Windows only ... I hope with the massive budget that AutoDesk has that they will port it over soon, In the last few years AutoDesk has become mac friendly.

While I own W7 for CAD and games . Most macs are more then able to handle the hardware load and with makers on many kinds of OSes Its smart to reach all of them.


Here is a Netfabb Alternitive that reemaj3D has found
3D printing Repair tool
Ive not yet tried it but its Web based and that means any Desktop OS can use it ,
( likely android and Chome OS too! )





Buying 3D Printed parts from others:


PerniciousDuke Has done a VERY good write-up on what to look for when buying 3D printed parts or full props.

Duke's 3D print Halo Props (What to expect from 3D)

Buying a pritner : its gonna be updated to be MUCH bigger soon
but here is a Great list from Trends | 3D Hubs




View attachment 25770

Also here are the trends to what is hot and not .


View attachment 25771


To be blunt :
Here is a shure fire list of a few machines Ive used that I Can vouch for

Under a grand and want a VERY good box to start on and have for a few years . Prusa I3 and its GOOD quality clones. $400-600
Prusa Steel Reviews & Ratings


Want to go big and blow 2200 USD? Then the Luzbot TAZ is the top of the class.
https://www.3dhubs.com/3d-printers/lulzbot-taz-5


Want a box that is a good over all value and can be a armor work horse in the shop? The flashforge Dreamer and Creator Pro are great!
https://www.3dhubs.com/3d-printers/flashforge-creator-pro
and
https://www.3dhubs.com/3d-printers/flashforge-dreamer
The two have the same internal frame and same hot ends and same qualty
the dreamer has a onboard ARM proc ( like a rasperryPi) with WiFI and a touch screen that makes it in stand alone mode a snap to use with NO PC near by.
the creator uses more open software BUT is more complicated .

Ill add more Good machines as I get time. but My list reflects the industrys stats

Got one you use PM!! me and Il add it !



I have at my lab both a Flashforge Dreamer and

I have a Rostock MAX https://www.3dhubs.com/3d-printers/rostock-max

https://www.3dhubs.com/3d-printers/rostock-max

What to avoid at ALL costs... and I do mean costs...


The * currrent gen* makerbots are $2500 ish and cant do ABS... the I3 can and its WAY cheaper
https://www.3dhubs.com/3d-printers/makerbot-replicator-5th-gen


The XYZ besides the $700 pro MUST use there DRM MicroChipped plastic . at 28 USD for 600 grams.
https://www.3dhubs.com/3d-printers/da-vinci-1-0
* at $ 700 bucks you can get a I3 and buy tons of plastic ! *
Please read the reviws and how nasty they are.



99% of the consumer 3Dp world is not Ok with Chipped DRM consumables
What works for your inkjet is not OK in Our book for 3Dp.

Yea you gotta * pay up* to play but once you are in, the filiment world is yours !

The Avg market rate is around $25 bucks a KG for Mid and good grade plastic ( 19-35 is the range you can find from Plastic trash to over priced )




Now on to plastic and why a heated bed is a MUST.
http://www.protoparadigm.com/news-updates/the-difference-between-abs-and-pla-for-3d-printing/


More to come .
Thank you for this. This was exactly what I was looking for to help with that push I needed :)

I know I'm a little late to the party, but I'd recommend getting an all-metal upgrade for your printer, as there isn't any PTFE in them. Both of my go-to's developed a hole in the ptfe tubing after a little time (50+hrs) would constantly jam filament and make purging nigh impossible. I've got a WanHao (PowerSpec) I-3 and mini (cantilever style) and there are upgrades available for both for the cost of a spool of worth-your-time filament.

I have recently purchased a 3D printer and want to print Halo 3 MKVI armor. What is the best type of filament to print armor with? I probably can’t print ABS the compatible Filament list says I can but the printer isn’t enclosed.

your cheapest option is PLA. I would recommend PLA + or aka PLA Pro. It has a bit more heat handling ability. Leaving PLA prints in your car on a warm sunny day can be rather bad for there health. And just because your printer doesnt have an enclosure doesnt mean you cant print abs. It helps. Abs is very prone to warping in the print stage. So a heated bed is essential. An enclosure just help a bit more and a basic one can be build out of sheets of plexiglass. In an old house like mine prone to wide swings in house temp and air currents ABS printing is rough without said enclosure..

Thank you for the response, between PLA and PETG which is better for cosplay use. I live in the desert and outside temp often reaches 115-120 fahrenheit so I’m also a little worried about heat damage just from being outside.

PETG is better for the heat where you live, unfortunately I have no idea how it fairs on finishing. I love ABS for it's finishing ability (sanding and painting).

On a slightly related note for others that use PETG (and maybe this will help Excelsior935)
1) How is the finishing of the product?
2) Does it sand well?
3) what is the best glue to use?

My experience with PETG has been less then stellar.. PETG is a food grade plastic it has excellent heat handling. I tried about this time last year to work with it and I could never get either of my printers dialed in. At that time there was no profile in simplifty to work with PETG. Every piece I printed failed structurally. I was in one of those I have a bad nozzle/feed kind of behaviors and I could not find the sweet spot with it. One of my friends has recently done some work on his S5 printer in PETG and he says simplify has a profile for it now but I just haven't gone back to try. From what I noted on my own prints and his. It leaves a lot of artifacts in the print process. a lot of strings and blobs because it oozes. The striations seem to be a bit more obvious. But in comparison to PLA it is a softer material when it comes to sanding and sands a lot easier. I only use a bit of super glue to stick things together and myself I tend to heat weld everything with a spade tip in my soldering iron. Personally I lean more to ABS if I were to switch over from PLA> Considering your heat ranges you are going to have to look at PETG or ABS in general. I wont say PETG wont work just my own experience is kind of flat and at 25 dollars and complete replacement of a hot end after the last attempt I am not inclined to try again.

ok I've 'tried' to read everything here but it may as well be in a completely different and very foreign language! I have recently bought a small 3d printer and a small hobby cnc and laser engraver. Now, I have no idea how to go from an obj or stl file (not even sure which format it needs to be in) to a completed print. I know about making sure print bed is level, hot, etc but its the software I am struggling with. I have fusion 360 which I have managed to ruin several files with, blender which, well its complicated lol and there is a program on the laptop called windows 3d builder? So, are there any really really easy idiot proof video tutorials that can guide me through set up of machine (s) to actually running a print please? And I mean its gotta be really really easy and simple to follow lol
many thanks from a 46 year old technophobe :confused:

You’ll need a slicing software such as Cura (free) to take an stl or obj and convert it to gcode for the printer. Easy as that. And cura has a ton of profiles for printers so chances are yours is on there. I’d imagine the same for your CNC and engraver (these two I’m not familiar with but operate similar to a 3d printer. So there must be software )
Here’s a tutorial series on how to get started. I thought this guys content was pretty good without getting too technical. But should get you printing

For beginners that are jumping into 3D printing and CNC as a hobby there's a few channels on YouTube that I watch in the background while working on projects to glean helpful tips.
Some are more technical, have brand biases (sponsorship), broad spectrum or hobbyist than others but they all cover good topics and have excellent presentation.
