Overview

Build a Delta 3D printer for the Hive.

Summary

Create a Delta 3D printer from some existing parts and 3D print the remaining parts.

Observation: The current inventory of arm rods, base plates, hot ends and motors are part of defining the printer geometry. Further design definition is required to document hot end dimensions including center of gravity and mounting in effector. This will constrain minimum effector dimensions. Selection of arm end attachment to effector and carriage (rod ends or magnet-ball) will further constrain the effector design. Using these constraints the effector geometry can be designed to maximize effector stability as defined in the excellent RepRap Delta_Geometry article.

The effector design, defines the arm spacing which is required to define the carriage. Once the column spacing, effector, arms and carriage are roughed out in dimensions the print envelope can be calculated.

Project Status

We are going through the existing parts (motors, carbon tubes, boards, build plates).

Got approval from the Hive for $250 to spend on parts and stuff.

Inventory of Stuff We Have:

Carbon fiber rods Clevis ends for rods

Carbon fiber tubes

Motors

Controller(s)

Hot ends

Base Plate(s)

Miscellaneous

Budget Tracking

Item Description	Cost (each)	Quantity	Cost	Remain
Initial Budget				250
Motor purchase	?	?	100	150

Project Needs

• Finalize design of 3D printed parts (corner blocks, carriage/trolly, hot end holder, arms)
• Print the pieces we can
• Figure out what we need to buy

Project Updates

January 30, 2018

Brad, James and Dave got together and decided on a triangle frame and two vertical rods per corner.
