Safety Guidelines


EVO is an advanced machine capable of reaching extremely high temperatures and fast speeds.

Please be aware of possible hazards when operating.


The heated bed can reach temperatures of 160C and also generates heat inside the enclosed chamber. The hot end can reach temperatures of 315C. Never touch the heatbed or hot end while hot, and keep in mind they may take up to 20 minutes to fully cool down.

Recently extruded plastic can stick to the skin and cause burns if not careful. Always wait until the hotend is completely cool before removing unwanted plastic or debris. The stepper motors can also generate high temperature and contact with the skin should be avoided.


Flammable materials or liquids should never be placed or stored next to the printer.


The internal electronic components can cause electric shock even when the printer is powered down or unplugged. Never remove the back panel without consulting your Airwolf 3D technician first. ALWAYS disconnect ALL power to the printer before performing any repairs.


Never touch moving parts or place your fingers in or on any of the belts, pulleys or gears while the printer is operational. Make sure to tie back hair and remove any dangling jewelry.



If you must leave the printer, make sure to hook up an external video camera for video monitoring.

Age: If under 18, do not operate the machine without adult supervision.

Choking Hazard: The machine features small parts which can be a choking hazard for young children.

Tips & Tricks

Avoid Cheap Imported Filament

  • While it may be tempting to go online and find the cheapest filament, believing all to be the same, this is a BIG mistake.  Cheap imported filament will affect not only the quality of your prints, but also the lifespan of your machine.
  • If you need a specific color that we do not sell, you can always request a particular color.  All of our filament is made from 100% pure plastic pellets.  We do not “cut” our filament with additives to reduce cost.
  • Cheap filament contains unknown fillers that can cause jams and ruin your hot end.  Melt temperatures may be inconsistent and these filaments frequently leave residue in your hot end, making your machine inoperable.
  • Here is an example of hot end teflon tubes that have been rendered inoperable because of low-quality filament:

Back To Top

Start Small

Small parts finish quicker and require fewer settings adjustments.

Back To Top

ABS Works Best

EVO is designed to print ABS continuously and it will give the best results.

Back To Top

Apply Wolfbite to cold or slightly warm bed

This ensures the best surface finish and longest life of product. It also reduces any chance that the glass will chip or break.

Back To Top

Filament Tips

  • Use high quality filament
  • Filament greater than 3mm may cause hot end to jam
  • Dry filament tends to print more consistently than filament subjected to moisture

Back To Top

Printing With ABS

  • Keep top on and door closed
  • Use either Wolfbite Original or Wolfbite Mega
  • Small prints require less heat on bed and in chamber
  • Chamber will rise to 50°C, even without chamber heaters
  • Fan speed over 40% may cause hot end temp to drop and jam hot end

Back To Top

Printing With Polycarbonate

  1. Apply fresh Wolfbite Mega on cool, clean glass
  2. Set nozzle to 290°C+
  3. Set bed to 150°C
  4. Set chamber to 60°C
  5. Use large (.25mm+) layer heights
  6. Keep infill speeds slow – fast speeds can cause skipping

Back To Top

Printing With PLA

Warning: PLA will eventually degrade and lose its material properties when left inside the EVO’s heat-retaining chamber.  In particular, PLA can crack and splinter in the 5/16″ Teflon feeding tubes and become difficult to remove.  Please use the following procedure when printing with PLA:

  1. Remove the top glass (to avoid trapping heat in the chamber)
  2. Nozzle temp should not exceed 240C
  3. Heated bed temp should not exceed 70C.
  4. Chamber heaters must be off.
  5. If possible, feed PLA from the top of the machine into the feeding system (to avoid passing through the Teflon feeding tubes).

Back To Top

Printing With Flexible Filaments Like TPU and TPE

  1. Replace your standard V.5 (or later) feeder with the “FLEX” feeder made available from 12/2019.  The FLEX feeder produces a stronger bite on the filament for better extrusion of softer materials.
  2. Update to firmware version 1.58.9 (or later) which more precisely controls side fan speed and hot end temperature.
  3. Update to Apex version 1.7.1 or later.
  4. Prior to loading filament, prime hot end with PLA. PLA will flush out existing filament and melt quickly when TPE or TPU is introduced.
  5. Slow down print speed to 16mm/s or less and increase retraction amount to 5mm or more.

Back To Top

Printing With HydroFill

  • New users should use a .8 or 1.0 mm nozzle when printing HydroFill Water-Soluble Support. The larger nozzle reduces back pressure and reduces the chance of jamming, especially with chamber heaters activated.  With that said, the updated G-series hot end incorporates Teflon feeders which greatly reduces the chance of jamming.
  • Prior to loading filament, prime hot end with PLA. PLA will flush out the existing filament and melt quickly when HydroFill is introduced.
  • Use a prime tower when possible to keep HydroFill flowing and primed between layers.

Back To Top

Precise Dual-Color and HydroFill Printing

Nozzle offset calibration is necessary for optimal dual nozzle printing.

1. Print out a sample dual material piece with walls abutting each other in both X and Y directions.

2. Measure second nozzle overlap in both X and Y directions, and save these values.

3. In APEX Software, navigate to Expert > Switch to full settings.

4. Once in the Full Settings interface, select Machine > Machine settings.

5. Under Extruder 2 settings, enter recorded X and Y overlaps.

6. Reprint test piece and perform again until walls cleanly adjoin one other

Back To Top

Small prints with curling from excessive heat

1. Lower print temp

2. Lower bed temp

3. Turn off chamber heater

4. Increase fan speed

Back To Top

Large prints with lifting

  1. Increase bed temp to 145°C
  2. Set chamber heater to 60°C
  3. Apply wolfbite over entire surface

Back To Top

Cracking in parts

Increase chamber temp to 60°C

Back To Top

Printing Large Parts

  • The most efficient and reliable way to print large parts is with either a .8 or 1.0mm nozzle.  Larger nozzles create less back pressure and are more resistant to jamming.
  • Part definition with large nozzles will still be high, especially when using “Fine” or “Precise” settings in APEX.
  • Print time with large nozzles can frequently decrease by 50% or more.
  • Strength – because wall thickness will be increased, parts tend to be stronger.
  • Check out Airwolf 3D’s guide to printing large ABS parts.

Borosilicate Glass Build Plate

The glass used for the EVO build plate is high-temperature, borosilicate glass. Like filament, the build plate is a consumable. It will degrade over time.

To prolong the life of the build plate, practice the following:

  • Only apply Wolfbite to a cold plate
  • After a print, be patient and let the surface slowly cool down until the part releases
  • Make sure the nozzle is not pressing the first layer into the glass — too close of a first layer will create a very strong bond that can damage the build plate

Running Out of Filament

  1. After running out of filament, it is not possible to remove remaining filament in feeders.
  2. Insert new filament into feeder opening, press FILAMENT CONTROL and then press PRIME.
  3. PRIME slowly feeds new filament into feeder. Do NOT press LOAD as it will force new filament in too fast and potentially jam.

Auto-Leveling Errors

  • EVO calculates values for auto-leveling by probing 4 corners of the print bed.
  • Z values are recorded when the aluminum nozzle makes electrical contact with the stainless steel bed.
  • Auto-leveling errors are most likely the result of a poor connection between the nozzle and the bed such as when material is blocking the two from touching.
  • Make sure that the M3 screws holding the orange sensor wire to the underside of the heater body are tight.
  • For best results, clean both nozzles and bed rails as described in the Maintenance section.

Warping (Parts Lifting Off Bed)

1. Use correct Wolfbite (apply while glass is cold).

ABS/PETG/TPU/TPE – Wolfbite Original
PLA – Wolfbite Nano (works best at 60-80°C)
ABS/PC – Wolfbite Mega
Nylon – Wolfbite Nitro
Polypropylene – Wolfbite Ultra

2. Increase temperature on bed.

PC: 155-160°C
ABS: 145-150°C
PLA: 70-80°C

3. Center print on bed for even heat distribution.

4. Ensure first-layer nozzle distance is correct.

Change to smaller-letter firmware, if necessary, to press first layer down.

5. If bed is cooler toward back, update to latest HEPA Fan Duct Design.

Print Too Close or Too Far From Bed

Too close (filament jamming into glass)

1. Make sure nozzle and bed rails are auto-leveling correctly (nozzle will quickly retract once rail is contacted — if not, refer to maintenance section to clean nozzle and rails.


3. Select a higher letter (“A” — closest to bed, “E” — farthest from bed)

Too far (filament barely grazing print surface)

1. Make sure nozzle is contacting bed rails during auto-leveling. If no contact, the Modular Hot End is grounding prior to auto-leveling.

2. Select SETTINGS and then UPLOAD FIRMWARE. Select a lower letter (A-closest to bed, E-farthest from bed)

Back To Top

Filament Jam

1. Heat nozzle to 20 degrees OVER recommended filament temperature (e.g. ABS to 260°C)


3. Press PRIME, and firmly press down on the filament to slowly push filament through the hot end. Repeat until filament exits tip of hot end.

If filament will not extrude, press REMOVE

If the above process does not remove the filament, use the following procedure:

1. Place machine in SERVICE MODE

2. Turn machine OFF

3. Remove two (2) M3 screws that hold front cover:

4. Remove front cover (not necessary to remove fan connection):

5. Remove four (4) M3 screws that hold feeder assembly

Layer Shifting

  • Generally, only one type of malfunction can produce Y-axis layer shifting in the EVO Additive Manufacturing Center: the shifting of the glass plate.
  • To make sure that the glass plate is properly positioned, the corner screws must NOT be fully tightened.
  • The corner screw and attached nut should be able to move around (yellow arrows) as the full upward force of the spring (red arrow) clamps the underside of the glass.

HydroFill or Nylon Not Extruding

  • If HydroFill or nylon is exposed to humidity, printing performance can degrade quickly. However, EVO’s heated chamber will eventually dry the filament.
  • For best results, use a .8mm secondary nozzle for extruding HydroFill.  This will reduce back-pressure and support reliable filament delivery.
  • Prior to printing with HydroFill, make sure to prime the second nozzle. Once material is flowing, EVO is ready to print.
  • Every 20-40 hours of dual extrusion HydroFill printing, prime HydroFill through with PLA.  This should be done at 240C.  Remove HydroFill and load PLA.  Once loaded, prime PLA until all HydroFill remnants are purged.
  • For nylon, it may help to replace your standard V.5 (or later) feeder with the “FLEX” feeder made available from 12/2019.  The FLEX feeder produces a stronger bite on the filament for better extrusion of softer materials.

HydroFill Prime Tower Falling Over Mid-Print

Update to the most current version of APEX to account for the unique first-layer bonding characteristics of HydroFill.

Side Fans Cool Off Hot End During Print

  • If the side fans cool off the hot end during printing, upgrade your EVO to firmware 1.58.8  (or later).
  • When necessary, such as in the lower portions of the print, or when running the side fans over a large flat area, this firmware modulates the side fans in response to hot end temperature fluctuations.

During Brush Cleaning Nozzle Pulls Out Of Brush

  • If bed lowers during auto-leveling such that nozzle pulls out of the brush, upgrade to firmware 1.58.8 or later. 
  • Earlier versions of the firmware may sense an errant ground connection between then nozzle and the brush when the EVO is performing its nozzle cleaning routine.  When this happens, the bed may lower and detrimentally affect the auto-leveling calculation. 
  • Upgrading firmware will limit ground sensing to situations only involving auto-leveling.

Printer Is Noisy

  • Firmware versions 1.58.8 and later implement a more sophisticated stepper control algorithm promoting quieter (and smoother) operation. 
  • Upgrading firmware will substantially improve printer performance.
