Wanted: Crazy Ideas! I'm building another RepRap! Ok... I have an i2 an i3 and I'm going to be building an i3-Mini... (Plus a SECRET 3D Printer - Details soon) But I don't want it to be just another i3. I want to hear some crazy ideas I could implement with it! I have no intention of using this as a daily printer, I just want to build something CRAZY! :) Or at least try some experimental stuff - Like a self leveling bed!! There probably are not many ideas, but I hope there are! https://reprap.org/forum/read.php?2,570995,570995#msg-570995 Mon, 11 May 2026 05:30:59 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?2,570995,779730#msg-779730 Re: Wanted: Crazy Ideas!

Whenever I get a new filament I find out the maximum extrusion flow rate i can achieve for a range of temperatures by manually extruding at increasing speeds until i start to see the drive gear slipping. I then set my print speeds based on this maximum flow rate. Infill at 90% of the maximum, perimeters at 60%.
With a pinch wheel or force sensor, and a bit of new firmware you could automate this process. And also create a closed loop feedback system to stop/slow the print speed if the filament slips.]]> Andy1989 Developers Mon, 09 Nov 2015 08:00:53 -0500 https://reprap.org/forum/read.php?2,570995,581857#msg-581857 Re: Wanted: Crazy Ideas!

Here's a crazy idea: how about making a small volume printer with an emphasis on high quality printing instead of lowest possible cost?
Pull out all the stops and put the best stuff you can find into making it as ideal as possible. Design in things like absolute rigidity, slop free bearings, adequate bed heat, flat bed, quality extruder/hot-end, etc.

Hey, that's my current project! A ~ 100x100x100 mm FDM printer with the highest precision in a budget of 600 - 1000 €.
Is that so crazy?! I thought it were very reasonable! :D]]> cristian Developers Fri, 06 Nov 2015 10:36:20 -0500 https://reprap.org/forum/read.php?2,570995,580524#msg-580524 Re: Wanted: Crazy Ideas! I'm building another RepRap! https://reprap.org/forum/read.php?2,570995,580524#msg-580524
This was then a 'closed' development, so no documentation 8-)

Now I have even better lasers in my basement and some of the needed parts too ... have plans to build a more modern SLS/DLM system for me with actual software, what's much easier and more comfortable, than self-programming all the converters and drivers for the device 15 years ago.

... but could be, I have a similar project starting next year with my company, so could be 'closed' again until 2017 :S]]> VDX Developers Thu, 05 Nov 2015 17:03:31 -0500 https://reprap.org/forum/read.php?2,570995,580487#msg-580487 Re: Wanted: Crazy Ideas!

The much bigger issue here is the FPGA programming. I would start with only doing the Step and Dir signal generation in the FPGA and using a stepper driver chip. Changing to h-bridge only should be easy to do later. PWM and PID should be the part where the FPGA can show what it can do. Temperture measurement might need an external ADC.

If someone write open source FPGA code that actually works on such a prototype I would do a shield for the Pi.]]> JustAnotherOne Developers Tue, 03 Nov 2015 12:56:26 -0500 https://reprap.org/forum/read.php?2,570995,579154#msg-579154 Re: Wanted: Crazy Ideas!

Automatic filament thickness measurement, to change the extrusion rate dynamically to account for the exact actual cross section of the filament.
Torque sensors on the extruder motor to dynamically adjust the temperature for optimum flow pressure.

A couple more ideas:

Turn everything upside down! or sideways! [3dprint.com]
Fix the extruder in one place and then move eveything else in XYZ, or just let the extruder move in Z.
Move everything with lead screws
Make a butane powered hotend! similar to [www.amazon.com]
3D print the entire frame
don't use a build plate, just print directly onto the table/counter/floor
Instead of a standard acrylic enclosure, build it into a nice hardwood kitchen cabnet.
don't use steppers, use DC motors with shaft encoders. Add some sensors to the extruders and use inertial navigation, or use a linear potentiometer for posistion feedback.

oh and of course you can add LEDs everywhere on it.

need any more crazy ideas?]]> AudaciousTuddle Developers Tue, 27 Oct 2015 12:01:36 -0400
