INTRODUCTION:
This guide covers only the physical assembly of the PVCore 3D printer. It does not cover firmware setup, etc.
A few months ago, I attended a STEAM (science, technology, engineering, arts and math) fair where a makers group was
displaying two commercial grade 3D printers, a PolyPrinter and a Makerbot Replicator. The most common questions I heard
about 3D printing where:
How much does a 3D printer cost?
Is it simple to use?
Is it easy to maintain?
It was no surprise that people walked away or their attention/interest greatly diminished when the first question was
answered. The PolyPrinter starts at about $4000.00 U.S. and the Makerbot at about $3000.00 US.
I realized that the beginner 3D printer enthusiast does not need a commercial quality printer, especially in a classroom
environment where more can be learned by tinkering than using. Most low cost 3D printers on eBay are either very low quality
come without instructions or have to be heavily modified to work properly. All of these factors lead to either an unfinished 3D
printer or a big paper weight. That is when I decided to design a simple PLA only 3D printer for the beginner 3D printer
enthusiast.
The following are a few design concepts I had in mind and tried to adhere to:
Half inch PVC pipe and connectors for the frame.
o
It’s cheap and easy to cut.
o
When designed correctly and at certain lengths, it’s sturdy.
o
Wide variety of connectors available.
3D printed parts for all other major components.
o
Motor mounts.
o
Bearing mounts.
o
Hotend carriage.
o
Etc.
Metric screws for attaching motors.
Non metric screws, washers, nuts, bolts, etc. are used everywhere else.
6mm smooth rods, bearings and GT2 belts for linear motion.
5/16 threaded rod for Z axis.
Open Source electronics and software.
PLA only with a non-heated, manually leveled print bed.
I could not have designed this printer without the assistance of my lord and savior, Jesus Christ, who always gives me good
ideas and allows my creative hands to do his good works...
Proverbs 2:6 For the LORD gives wisdom; from his mouth come knowledge and understanding.
