Completely new design as required
1000mm Tall 40x80 C-Beam extrusions by OpenBuilds so that the the carriages ride in the channel to keep the belts away from the heat as well as the wheels
1000mm Tall 40x80 C-Beam extrusions by OpenBuilds so that the the carriages ride in the channel to keep the belts away from the heat as well as the wheels
· 1000mm tall 20x20 extrusions as a vertical support to the upper rails and extra space
· 500mm horizontal 20x20 black anodized extrusions
· V-slot wheels
· Belts are in the internal extrusions to reduce amount of stretch and wear due to heat
· Cherry Pi IIIS derived Spherical Spectra String mounted effector for precision and no backlash (3S)
· Hotend is undecided (E3D Chimera Volcano) or E3D V6 Volcano
o All-metal
o 300C capable
1 E3D V6 with a .25 nozzle (dual bowden feeding system)
1 E3D Chimera Volcano with .4 nozzle and 1.2mm nozzle (Quad bowden feeding system)
1 E3D V6 with a .25 nozzle (dual bowden feeding system)
1 E3D Chimera Volcano with .4 nozzle and 1.2mm nozzle (Quad bowden feeding system)
· Automated Tool Changing via electromagnetic kinematic coupling on the effector
· cross bracing 500mm 20/20 black anodized extrusions to resist torsional loads
· Hidden- Rotating tool holder on the X-braces to maximize build area
· 2 Watt Laser cutter/engraver
· Multi-Syringe Extruder
· Large Pick-n-place for mounting electronics, Auto-ejection
· Multi-Cylindrical Tool (Pencil, Pen, X-acto Knife, Sharpie, conductive ink pen)
· Recirculating Carbon filter and HEPA filter
· Heated Build Chamber (at least 50C)
o 24V Ceramic Heater mounted to the upper portion to increase chamber temperature
o R-tech insulation to reduce heat loss
o Sound Dampening panel
o Metal panel to increase rigidity
o Polycarbonate Door with electromagnetic latch
· Water cooled system
o (6 Steppers (min.))
o Hotend(s) watercooled
o 120mm Radiator mounted above
· Out of filament detector with automated pause and growl push notifications via octoprint
· Built-in custom OctoPrint with Raspberry Pi 2
· RGB lights mounted behind 40x80 V-slot extrusions for even lighting with light change depending on machine state(On, Heating, At temp, Printing, Cooling)
· Dual Synchro Gear Float Extruders
o # of extruders still undecided
o Using a TB6600 Stepper controller to control a High torque NEMA23 for high speed and torque without resorting to gearing.
o Hobbed pulley geared 1:1 to have more contact on the 1.75mm filament
o Extruders float above the effector via a counterweight pulley system with spring tensioned connectors to carriages to resist the momentum changes due to high speed effector OR - Have the extruder on a carriage connected to a counterweight so that it travels up and down
· FSR AI Heuristic Calibration
· Astroyn Dampers
· 400mm Build plate
o 16" Mic-6 8mm thick aluminum plate (tolerance .005") for build plate
o Build plate is a .003" PEI sheet to remove the need for additional adhesive
o 24V 400 Watt Silicon Heater
o Mounted with 3 point magnetic Kinematic Coupling with 10 micron repeatibility (Proven by MIT thesis by Raymond Ma that kinematic coupling is the absolute best way for repeatability.)
o XT60 Connector for disconnecting buildplate
· Soluble support mixer built-in
o Fan+Nd magnet underneath build plate to create a stir mixer
o Heated bed to create heating element for the solution bath
o PLA is used as soluble support via a NaOH solution in a 60-70C solution for about 3 hours.
· Dual camera monitoring via Octoprint
o Webcam monitoring the build
o Webcam monitoring controlled by servos with tilt and pan capability.
· Rotating Turntable using Open-Source Ciclops scanner combined with webcam used for monitoring
· Extendable universal spool holder with dehumidifer
· Purge and Wipe brush built-in
a Adjustable spool holder for varying spool sizes
a Adjustable spool holder for varying spool sizes
Other Technical Specs:
· 16-tooth Pulley for Torque
· 1/16 Microstepping
· Smoothieboard
o Shake firmware
· 7" Galaxy Tab 4 for local control via SSH to Rpi 2
· 800 Watt 24V PSU
· NEMA17 86-oz. in holding Torque
· 1.75 Filament
· 400mm diameter x 450mm? height
