Extruder Carriage Solution EE 400DPeter Flores3Extruder
carriage
The ProblemExtruder Carriage is prone to melt when extruding ABS
plasticCurrently made out of PLA plastic (Melting Point: 190 C)What
is an extruder carriage?Extruder has two parts: hot and cold
endCold end feeds the ABS or PLA plasticHot end contains the
pointed nozzle which melts and extrudes the plastic to be
printedThe extruder carriage is all of these parts together with
the axisRequirementsDesign an extruder carriage that is under $50,
can be assembled in a timely manner (2 weeks), does not melt (cant
exceed 250 C), and does not affect the operation of the printer.
Needs to be a material with high heat resistance and low thermal
conductivity
IdeasBuy new carriage via Ebay, RepRap vendors, etc.Moving the
hot end of the extruder from the center to the sideUsing a
different material such as acrylic or plywood or ABS
Buying New Extruder Carriage
$15.00 via Ebay + shipping
PROSPreMade
CONS Paying for carriageModifications on current
printerRemounting Extruder CarriagePROSNo need for new printed
parts
CONSRequires complete overhaulUnsure if reconfiguration will
guarantee no meltingOur SolutionWorking with Steven and Sirac and
the 3D Printer Club to create a new carriage using ABS plastic
Material: ABS Plastic Filament - 1.75 mm
Cost: $0 20
Deadline: Monday 10/15

3D Printer ResolutionPeter Flores
12RequirementsIncrease the print qualityCost Under $50Use parts
that are ubiquitousReduce and minimize chance of backlashAssembly
Time: 2 weeks
BacklashBacklash is the amount of clearance that is given
between two connected pieces
Theoretically want zero backlash however backlash must be
present to prevent jamming, allow for lubrication, manufacturing
errors, etc.
Wikimedia CommonsMust use a belt/pulley combination that allows
for minimum backlash!!!BeltsFor the 3D Printer, it is ideal to have
a belt that is designed for linear motionMost Commonly Used BeltsT5
(European)T2.5MXL (Imperial)GT2 (State-of-the-Art)
PulleysBest performance requires at least 6 teeth to be in
contactPractically must be achieved 18 24 teethSmaller Pulley will
give more torque and, therefore, more resolution

build timeThe acrylic case should take about one to two weeks to
build.The filter and tubing should take two-three days.Testing dead
zones and fans should take about a week.TestingWe will be testing
dead zones with thermometers.We will place fans according to where
its too hot in the casing.We will test which fans can suck in
efficient amount of air.
Further TestingWe built a prototype of your filter using PC
fans, PVC pipes and raw carbon.We found it to be effective In
eliminating most of the fumes that were emitted from burning
plastic.
