Introduction

The PipeDream project aims to lower the cost of entry to 3D printing in nylon without sacrificing an acceptable level of print quality. To this end, we began with easily and cheaply available 6" I.D. PVC sewer pipe as the gantry (or frame). Windows will be cut in the sides of the print area for access, and printed end-caps will be used for the top and bottom, to mount the vertical parts for the carriages to ride on. Every effort is being exerted to make the bulk of the parts purchasable at local hardware stores/home centers, such as the 1/4"/20 threaded rods for vertical drive.

Specifications

• Printed Parts: ~20
• Non-Printed Parts: ~20 not counting screws, nuts, etc. More accurate counts and a parts list are being generated as work progresses on the design.
• Total Cost: US$200-250
• Material Cost
  • Printed Parts: ?
  • Vitamins: TBD - gantry plus vertical rods ~US$25
  • Electronics: TBD
• Printer Dimensions: 165mm dia x ~400mm tall
• Build Area: 125mm dia x 300mm tall
• Precision: ???
• Accuracy: ???
• Speed: slower than Rostock due to threaded rod for vertical drive
• Units of Measurement: Metric, even if it's built with SAE hardware...

Features

• Rigid PVC pipe gantry
• J-head style hotend
• Simple gantry assembly with minimal tools, easily adujsted (prior to printing parts) for metric or SAE to suit local needs
• Will print in PLA or Nylon.
• 56% Plastic, 44% vitamins (Volume)

Additional Info

• Estimated assembly time = 2 - 3 hours (excludes electronic/board assembly)
• Estimated total print time of a printed set = 28+ hours
• Estimated total plastic usage of a printed set = 370 cc @ 60% infill
• Power requirement = 80W to 100W (Hotend @ 240C, Hotbed @ 95C)

Documentation

• None yet. Working on it!

Future Development

• Add a heated bed to allow printing ABS
• Add LED lighting to illuminate print volume
• If proof-of-concept works to an acceptable standard, a local construction company has donated 12" I.D. PVC sewer pipe to the project
• Kits and outreach to low-income people
