Solution: Contact the manufacturer to calibrate the parameters

Cause 2: Damage of the window mirror of laser

Solution: Replace the window mirror of laser

Cause 3: Unstable environment temperature

Solution: Ensure the environment temperature is between 22 to 26 degrees

 

Q3: No laser output

Cause: Turn on the laser software and calibration software at the same time Solution: Turn off the laser software or calibration software, then restart the iBuild.

 

Q4:Laser alarm, the temperature of the laser head is floating, NO laser output

Cause: The internal crystal temperature parameters of the laser and the environment temperature are unstable

Solution: Contact the manufacturer to calibrate the parameters and ensure that the environment temperature is between 22 to 26 degrees

2.The iBuild Troubleshooting

Q1:RTC4 error

Cause: Turn on the laser control software and calibration software synchronously

Solution: Turn off the laser control software or calibration software

Q2:The iBuild alarm “Laser power is too high or too low”

Cause: The detected laser power is not within the range of “Power Detection Maximum and Minimum RMS”.

Solution: 1) Recalibrate the laser power

2) Modify the “Target Value” or “Power Minimum RMS Value” and “Power Maximum RMS Value” of the laser power

Q3: The iBuild alarm “Liquid level is too high or too low”.

Cause 1: The volume of resin in tank is above or below standard and cannot be adjusted by the resin plunger.

Solution: Add or remove some resin. Cause 2: The resin level sensor has no signal and can’t detect the resin.

Solution: 1) Clean the bottom of the resin level sensor

2) Adjust the angle of resin level sensor

Q4: The iBuild indicates resin level fluctuation error

3.Dimensional Deviation

Q1:Large dimensional deviation in XY direction
Cause: The XY dimension factor in the iBuild is unreasonable
Solution: 1) Print the “100mm Cross” size test samples, measure the size and recalculate the XY size factor
2) If the short size is accurate but the long size has a large deviation, set multiple sets of XY coefficients of different sizes or reduce the length of parts over 200mm by 1/1000-2/1000 before printing

 

Q2:Large dimensional deviation of printing parts in Z direction
Cause: The parameter “Z-axis Compensation” is unreasonable
Solution: Modify the “Z-axis Compensation” parameter in the slice software setting

 

Q3:Printed samples are assembled too loosely and the gap is large
Cause: The laser beam compensation value is too large
Solution: Modify the laser beam compensation value

 

Q4:Printed samples are assembled too tightly or cannot be assembled
Cause: The laser beam compensation value is too small, and the reserved space in the design drawing is not enough
Solution: Modify the laser beam compensation value

 

Q5:The size of the same length parts printed at different platform position vary widely 

Cause: Calibration isn’t up to standard
Solution: Recalibrate

4.Printed Samples Deformation

Q1:The bottom of the printed sample is deformed, warped, or uneven, etc.

Solution: Adjust the height of the recoater
Cause 3: There is no adsorption in the recoater
Solution: Control the recoater adsorption by adjusting the vacuum pump
Cause 4: The resin is sticky
Solution: 1) Turn on the heater
2) Lengthen the time of “Delay after Platform Settling” and “Delay after Recoater Movement” in iBuild settings

Q2:Broken printed samples only appear on the left or right side of the platform.
Cause: The blade heights on the left and right of the recoater are not level
Solution: Adjust the height of the blade on the left and right of the recoater
Q3: Broken printed samples only appear in the front and back or a corner of the platform
Cause: The marble platform is not level
Solution: Adjust the level of the marble platform and adjust the height of the recoater

Q4:The printed sample located in a specific position on the platform is partially broken
Cause: F-Theta is dirty
Solution: Clean the lens of F-Theta

Q5:The printed samples are not well formed or the holes details of the printed samples are not well printed out, or the edges are cured with excess flakes
Cause 1: The lens from reflection mirrors, beam expander module, galvanometer and F-theta are dirty.
Solution: Inspect the lens and clean it.
Cause 2: The laser window mirror is damaged
Solution: Replace the lens of the laser.

Q6:The printed samples are staggered or faulted
Cause 1: The platform is loose or the z-axis coupling is loose
Solution: Reinstall and locking the platform and the z-axis coupling
Cause 2: The device is turned on to heat, but the temperature is unstable
Solution: Turn off the heater and contact the manufacturer.

Q7:The printed samples come out with pits on the Surface
Cause: The surface temperature of the print is too high
Solutions:1) Reduce the laser power and speed up the scanning
2) Increase the value of the parameter “Delay after Laser Scanning” in the iBuild

6.The Printed Sample Surface is Peeling or Bubbling

Q1:The printed sample surface is peeling or bubbling
Cause: The distance between the border and the hatch is too far
Solution: Decrease the value of “Transition Area Width” in the iBuild parameters

 

Q2:Peeling, blisters appear in only one or two directions around the printed samples
Cause: The beam is oval or not concentric
Solution: Recalibrate the light chamber

Q3:Peeling and bubbling appear at the bottom of the printed samples
Cause: The distance between the resin level and the recoater is too large
Solution: 1) Adjust the height of the recoater

Cause:The fluctuation of the liquid level value is too drastic
Solution: 1) Clean the bottom of the liquid level sensor
2)Adjust the angle of the liquid level sensor
3)Check if the vacuum pump is leaking

 

Q2:The sides of the printed samples are scorched, and the samples have blanks and burrs all around

Solution: Appropriately reduce the laser power of the hatch and border

 

Q3: “Orange Peel” and “Water Ripples” appear on the side of the printed samples
Cause: The distance between the border and the hatch is too far
Solution: Properly increase the “Transition Area Width” in the iBuild settings

 

Q4:There are good textures in two directions, and bad textures in the two directions
Cause: The variable laser beam appear to be an ellipse
Solution: Recalibrate the optical circuit

 

Q5: The plane printed samples print out regular stepped, horizontal lines.
Problem: The plane samples are not parallel to the bottom surface of the platform when the part is placed, and the inclination angle is too small.
Solution: Reorientate the printed model to ensure that the bottom of the model is parallel to the platform or tilted more than 45°.

8.Support Problem

Q1:The support is too sticky to the platform, short, and the bottom is obviously wavy
Cause: The platform is too high when the beginning of the print. 
Solution: Modify the value of the iBuild parameter “Print Start Position” according to the actual situation

 

Q2:Before the recoater is applied, the support cannot be connected, and there are many support points floating on the liquid surface.
Cause:The support scanning speed is too fast, and the resin is not leveled
Solution: Appropriately reduce the scanning speed of the support and lengthen the time of the iBuild parameter “Delay after Platform Settlement”

 

Q3: It appears that the support cannot be connected without the coating, and there are many support points floating on the resin surface.
Cause: The support scanning speed is too fast, and the support does not have enough time to reset after coating
Solution: Appropriately reduce the scanning speed of the support and lengthen the time of the iBuild parameter “Delay after Recoater Movement”

9.Recoater Problem

Q1:No adsorption in the recoater
Cause 1.: The adsorption force is small
Solution: Adjust the knob of the vacuum pump to increase the adsorption force
Cause 2: The adsorption trachea is blocked or ruptured
Solution: Replace the adsorption air tube

 

Q2:The broken parts cause the recoater to be stuck and unable to move, and the software cannot control the movement of the recoater
Cause: The motor is blocked, causing an alarm
Solution: Helios-P series (reboot the device)

10.Other Problems

Q1:The printed samples with wall thickness of 1mm or less are soft.
Cause 1: The parameter “Thin-Wall Judgment Threshold” in the iBuild has no value
Solution: Make sure that the parameter “Thin-wall Determination Threshold” in the iBuild is set to option 1
Cause 2: The scanning speed of the thin-walled area is too fast and the laser power is low
Solution: Appropriately reduce the scanning speed of the thin-wall area and increase the laser power

 

Q2:Insufficient strength and brittleness of parts
Cause 1: The samples are over-cured (hard enough)
Solution: Increase the value of the iBuild parameter “Filling Spacing” to increase the scanning speed
Cause 2: The samples are not fully cured (slightly soft)
Solution: Reduce the value of the iBuild parameter “Filling Spacing” to reduce the scanning speed
