SainSmart Assembled J-head Hotend Nozzle 0.35mm for 1.75mm Nozzle Fitting, 3D Printer Printing Filament Reprap MakerBot Kossel Delta

Removed the heat sink and added a series of vents to provide cooling. To
reduce weight, an aluminum nozzle is used.

This J-Head Hot End is designed based on other nozzle. It’s very simple by
reducing the number of custom machined parts to a bare minimum.

The J-Head Hot End can easily and well interface with the most popular RepRap
extruders. The filament path is same with the one of an already proven design,
it can be used to print reliably with both ABS and PLA. If using PLA, it
requires a small fan to provide air-flow through the cooling vents milled in the
sides of the nozzle holder. Besides, the Hot End has another two advantages.
Heat transmission is more efficiency as there is no thermal junction where a
separate heater screws onto the nozzle. And a resistor is used as a heater.
There is no need to wrap nichrome wire or to bake a heater core.

Features:

* Resistance of resistor 4.7Ω

* Resistor rated power 8W

Ship By Express Unassembled-Full Kit Reprap Delta Rostock Mini 3D Printer Sanguinololu V1.3a PEEK J-head hotend extruder

The Rostock mini is a delta 3D printer based on the modified design of the original Rostock created by Johann. The printer is designed to have a smaller build volume allowing for a smaller, more compact, portable, and desktop friendly version of the delta RepRap design. Using OpenSCAD, the parametric nature of the design files allows for print surfaces to be configured that range from as small as the default 152×152 mm (6×6 inches) all the way to 300×300 mm (12×12 inches) or more. Further, construction parameters such as the length of the drive belts, diagonal rods, and a laser cuttable frame as well as the firmware parameters such as diagonal rod length and delta radius are all automatically calculated based on the size of the specified print surface.

3D Industries, ALUHOTEND Aluminum and Steel Metal Hotend, 1.75mm, .4mm nozzle J-Head for Prusa and other 3D Printers

The Aluminum Hotend AluhotendV5C-1.75mm is designed by the well known RepRap designer, “The Jolly Grim Reaper”, and is configured for high resolution printing with PLA, ABS and NYLON. This hotend includes a 0.4mm nozzle – though a 0.3mm nozzle is available from the manufacturer.

Plastic body (PEEK) hotends can fail when the PTFE liner swells from excessive heat. The PTFE liner can push the barrel out of the PEEK tube, forcing the heater block and nozzle to literally fall off the printer, resulting in a ruined print and a disappointed print owner. We don’t want to get rid of the PTFE liner because it serves as a non stick surface that your filament can glide over. In fact, PTFE is the same material used in most non stick frying pans. The Jolly Grim Reaper came up with a satisfying solution: keep the PTFE Liner, but replace the PEEK with an aluminum body and use a strong steel barrel that the PTFE cannot force out. As long as you configure the ALUHOTEND with a fan and avoid exceeding the recommended temperature at 245c, you should be able to reliably and consistently get high resolution prints with a minimum of fuss.

Note, this hotend requires a fan (included) blowing on the heatsink for proper operation.

Product Features

  • 1 x AluhotendV5C-1.75mm Aluminum Hotend, 1.75mm, .4mm nozzle standard J-Head
  • 100k thermistor (number 10 on the marlin firmware) with sleeves and heatshrink.
  • J-Head grove mount (aluminum)
  • 1 x 40mm 12v fan
  • 1 Heater cartridge 12v30w

Getech Kossel Delta All Metal J-head Hotend with Line for Bowden Extruder


The Bowden principle:

The Bowden cable lets you reduce the moving mass of the extruder and thus allowing faster controlled motion, less shaking of your machine, less energy use and importantly: faster printing! Normally the mechanism that drives the filament into the hot end (where it melts) is directly on top of the extruder. This creates problems of balance and oscillations with faster motion which you can see in your printing results and hear and feel when your machine is shaking.

If the filament drive mechanism is placed on a non-moving part of the 3D printer, it can be pushed into a tube. PTFE (Teflon) is useful because it is slippery: it has little friction with the plastic.This limits wear and loss of energy. The tube’s other end is connected to the extruder’s hot-end.

The concept of using a Bowden cable as guide was suggested and pioneered by Ed Sells.

The main advantages:

All metal enables working with Polycarbonate up to 300 degrees Celsius and with future materials that require higher working temperatures beyond those supported by plastic extruders and hot end.

Tested with PLA, ABS, polycarbonate, nylon and PVA.

Features:

It is assembled with 4.7ohm 8W resistor and 100K NTC thermistor.

To make your printing easier,a 30x30mm 12VDC cooler fan is assembled for heat dissipation.

The inner diameter of the bowden feed mouth is 4mm to print with 1.75mm filament,and 6mm to print with 3mm filament.
