"Tac Tac" sound when printing with ABS

My 3D printer makes weird sounds. When it's at >75% printing speed the extruder motor makes a "tac tac" sound and it goes backwards, pushing the filament back, for a small interval of time. I have tried changing the nozzle temperature and I'm unable…

How do I get a replacement PTFE tube to fit inside my nozzle?

I have been getting clogs and believe that it may be due to a damaged PTFE tube inside my hot end. I have a replacement (it came with my printer), but I can't seem to fit the tube into the nozzle. I also tried to turn the original PTFE tube around,…

Enclosure, things to pay attention to?

I got an Anet A8 and want to build an enclosure for it. Since I'm currently only printing PLA, I would do it mainly for noise cancelling, because I have to run it in my room. I however want to have the possibility to upgrade it later with, say, an…

Can cheap hotend parts sourced from China actually produce good prints?

TL;DR Is it possible to build a hotend, using separate parts, sourced on eBay, from China, and still achieve a high quality print? In my opinion, the E3D V6 hotend is rather expensive, at $/£70, especially to those building to a tight budget. Now,…

Would using a leadscrew with 1 or 2 mm lead, en lieu of 8 mm, result in a better printer?

By "better" I mean "more precise"... With respect to a RepRap P3Steel or Wilson II, I am getting some 330 mm T8 leadscrews for the Z-axis movement. There seems to be a choice between a lead of 1, 2 or 8 mm - the pitch is 1 mm in the first case and…

Taking a new hotend into operation (cleaning, forming, etc)

When installing and using a new hotend for the first time, which steps of action should be taken before. This will probably be more applicable to chinese clones than to authentic products (is the statement true?): Should a certain cleaning procedure…

FDM layer bonding strength

I'm looking for some advice, rules of thumb, or models for how to design parts for layer bonding strength. As an example part, lets assume a circular beam in bending (tall cylinder). Depending on how the part is setup on the build platform (tube…

Weight Reducing Design Change for Extruder Driver

I'm considering removing the driver motor from the extruder assembly, and placing it on a stationary mount point instead, and then using a flex-shaft type connector from the motor to the extruder assembly to actually drive the extruder. The…

Can a 3D model of a copyrighted work be rendered legally without infringement?

I know this is still gray territory and it is asked so many times within the 3D printing and maker community but I'm curious about the limits of 3D models and were it touches on Free Use and infringement. I'm not trying to push the envelope, I just…

Maintaining fine details while applying smoothing methods

I've been reading and experimenting with Acetone vapour smoothing on some printed ABS parts. My problem is that I need to selectively smoothen the printed parts which vapor smoothing doesn't allow. In particular, the cogs, whose sides I was trying…

Are there many assembly type 3D printers?

I am wondering if anyone here knows of any 3D printers that work by assembling models from parts instead of extruding or setting material. The closest I have found is the pixelstone but it appears to only be a prototype and I haven't seen or heard…
