Re: An idea for increasing the Z-axis strength of printed parts - 8 years ago
QuotebdurbrowThat is a possibility... my sticking point with two part epoxies though is that it sets up in the nozzle after the print is done... requiring a disposable nozzle; or some sort of solvent flush system. Not an insurmountable obstacle... but definitely something to be aware of before heading in that direction. They tend to also be somewhat expensive... there are some single component epby Frans@France - General

Aceton vapor would be dangerous. But I like the idea about using welding. Why not ultrasonic weld the layers? No need for holes but just an extra "extruder" that welds at certain point the layers.by Frans@France - General

Re: ABS delamination from heatbed - 8 years ago
First thing I notice is the space between the lines in the rim. looks like under extruding and would explain that the brim doesn't help as much as it could. Did you measure the average filament width and entered that value in the slicer? Why the PVA/Water mix, why not the ABS/Aceton? PS I'm seeing warping and not delamination?by Frans@France - Printing
Re: An idea for increasing the Z-axis strength of printed parts - 8 years ago
So maybe this "Hybrid 3D printer: FDM + Polyjet" will be an idea? 3D print with holes and then use the motor driven syringe to deliver a "filler" to the holes. Using 2 part poxy and a mixing nozzle would do the trick.by Frans@France - General

Re: Filament chips? - 8 years ago
rfid on the spool, rfid reader on the printer. Develop some rfid admin software to setup a relation between rfid number and printer&slicer settings. Then write an plugin for the 3d printer control software so It can connect to the rfid reader and rfid admin.database. Let that plugin then take the appropriate actions.by Frans@France - General
Re: CTC Prusa i3 does not extrude - 8 years ago
maybe a) temperature too low b) nozzle blocked c) screw that pushes the filament onto the bolt too lose d) not enough voltage to the extruder motor if you can push it by hand and that is not too difficult then a and b are unlikely and either c and d or both could be the issue. I would start with c But if you mean with skip that it stops then it might be d, if you mean it turns but the filamentby Frans@France - Printing

QuoteMechaBits So what are the layer heights on the 1.2mm nozzle, I bet print speeds quite nippy. I did a 0.8 layer, speed was hard to tune, the filament is fed fast so there isn't much time to heat up to a good print temperature. As I said here "I might be able to push the volcano to 30mm/s, I failed at 35mm/s but it might be that replacing the Wade extruder for a full metal extruder would alloby Frans@France - General

Printing ABS @265C with a E3D volcano 1.2mm nozzle will have no issues with interlayer bonding if you print with 100% infill the part will be very strong. The blog post states Quotethe tabs on the part printed with a standard 0.40mm nozzle could be broken by hand if you really try. However the same features printed with Volcano were impossible to break with bare hands, and we really tried! Eveby Frans@France - General

Re: Z axis not working properly - 8 years ago
Quotethe_digital_dentist Nope. The basic spec on the full step accuracy is usually 5%. That's why going to >16:1 microstepping doesn't result in increased resolution (it will reduce noise and vibration, but you won't get finer positioning precision). You're right, I should have search for it Quotethe_digital_dentist A geared motor will increase torque but reduce speed. If you can live wby Frans@France - Developers
Re: Z axis not working properly - 8 years ago
Quotethe_digital_dentistMotors do not step perfectly- there is typically a 5% spec on step to step position. What happens when the motors don't step exactly the same, say one is +5% and the other is -5%? Combine that with microstepping and I think that you're asking for a lot of easily avoidable trouble. isn't that 5% for microstepping? Using a geared nema17 maybe an option?by Frans@France - Developers

Re: Optical mouse sensor as position feedback - 8 years ago
Ahh..I now read that you want to measure the belt and not the motor..silly me That would work rather well I think, mounting is then easier and you can beter control the distance between the belt and the lens of the sensor.

Re: Problems with Larger Nozzles - 8 years ago
ABS or PLA? I had to retune the slic3r settings for my 12v 3.00mm E3D volcano completely. Most importantly I had to increase the nozzle temperature for ABS @layer 0.9mm (used to be 0.1 or 0.2mm) to ~260C (used to be 210C) and slow down the print to around 25mm/s (used to be 100-120mm/s). I needed to change these two settings because the ABS didn't stay long enough in the nozzle to get heated upby Frans@France - General
