High-Flow Hot-End Project

Welcome to our main page for the high-flow hot-end project. Conceived by Peadar, the aim of this project Is to develop a hot end capable of printing a sub-10 minute benchy!

Here is our plan so far:

1) Heatsink (Will, Matthew)

Task:

Develop simple first prototype heatsink

Goal:

Determine machining limits that will control heatsink design and material choice

Requirements:

Group mount fitting to extruder motor

Fit E3D heat break

2) Heatblock (Josh, Akash, Ioan)

Task:

Develop simple heat block

Goal:

Determine machining limits that will control heatblock design and material choice

Requirements:

Can fit standard thermistor and heater

Fit V6 nozzles

Fit E3D heat break

3) Heater (Ioan)

Task:

Explore cylindrical heaters

Goal:

Evaluate the manufacturability of a cylindrical heater

Requirements:

List of possible configurations

List of pros and cons for each

4) Extrusion test rig (Peadar, Will)

Task:

Design system for testing the extrusion flow of a given hotend

Goal:

System for performing extrusion flow tests

Requirements:

Group mount for any hotend

Direct drive extruder

Control board with editable firmware

Pronterface/Raspberry Pi for interfacing

Experiment G code

A frame for assembling the test rig

5) Design of experiments (Peadar)

Task:

Create a set of experiments to gain an understanding of variable relationships

Goal:

Set of relationships relating volumetric flow to internal heater block design parameters

Requirements:
