① Please insert a spring on a stud.
② As shown in the picture below, there is a hole in bottom left part of the bed where you can insert the stud.
③ Place the head of the stud facing bottom and insert it into the hole.
④ In order to secure the stud, place an E-ring to the stud while being pushed upward. Use proper tool such as Long-nose as shown in the image below
※ After assembly is finished, press the stud from the bottom 2 to 3 times to make sure that vertical movement is smooth.
Function of the Stud is to secure the bed not to move after printing is finished.
Stud’s presence or absence does not affect the quality of outputs or any other features of the device.
②Press the upward arrow
→ See if the filament comes out
→ If it does not, please proceed to page 2
2. Remove Tube from the Nozzle
Use a tool such as a LONG NOSE PLIER and pull to see if it comes out.
If it does not, proceed to the Page 4
※ Reassembling the Nozzle Tube
 Insert Tube
- Insert the tube all the way in until the tube below the black tape is unseen. (About 50mm inserted = 1.96 inches)
Insert the Snap-Ring in between the Fitting and Holder.
- Approximately 1.5mm can be additionally inserted.
3. Remove Tube from the Inner Side (Only try this if the previous steps did not work)
Pull the tube while pressing the blue Cap.
Use a toll such as a LONG NOSE PLIER to see if It comes out.
After removing the Filament, insert the Tube back in all the way (about 15mm = 0.6 inches).
The newest Filament that has been excreted on the highest layer has a higher chance of warp, which is the reason why the corners of the 3D models warp.
ABS Material has more tendency to warp than the PLA material.
Warping Improvement Instructions:
1. Operate 3DWOX at a fairly warm temperature (61 ~ 84 ℉)
- Cold weathers can cause warp in the printed models.
2. Close all the doors while printing.
- Opening top and front doors can affect the printed model
3. In cases where the shape of the 3D Model has a Countergradient or Bridge shaped bottom, please turn off the fan.
- In order to change the Fan settings, change the mode to advanced mode.
- Go to Settings - Advanced (2) - Cool - Minimum/Maximum Fan Speed and change the values.
- Default value for PLA is 50% and ABS is 3%
4. Change the Infill rate of the model.
1) Change to Advanced Mode(Mode - Advanced Mode)
2) Change the Infill Rate (Settings - Basic - Fill - Fill Density)
- Default value for PLA is 15% and ABS is 10%
5. Go through the manual Leveling.
- Please refer to the attached file.
6. For large sized models with large bottom surface, please print with PLA.
- ABS has a tendency to contract easily.
7. Please print the model in the middle of the bed.
- Corners of the bed sheet (especially close to the front door) are easily affected by the outside temperature, causing warp.
8. Use as least time as possible for pausing.
- During the pause, the inner temperature of the 3DWOX decreases, which can affect the warping of the 3D model.
(Refer to the following link: http://3dprinter.sindoh.com/ VideoTutorial , "BedLeveling")
1. Get a business card (or a hard surfaced paper)
2. On the printer display, go to Setting - Z offset
- Move The nozzle and the bed will move around and eventually the nozzle will position on the middle of the bed
3. Pull the bed until the Sindoh logo is covered
4. Push the business card in between the nozzle and the bed and move it around. If you feel a little bit of scratching the bed level is complete.
※ Caution. There is a spring system under the bed. If you press the bed down while moving the business card around, the bed will move downward, causing an incorrect leveling of the bed.
- If you cant move or cant fit the business card in between the nozzle and the bed = Increase the Z offset value and press move
- If you cant feel any scratching on the business card = Decrease the Z offset value and press move
- On the appropriate Z offset value, press save
5. Push the bed back and manually move the nozzle to the left end.
Same way as Step 4, push the business card in between the nozzle and the bed and calibrate until the appropriate height.
During calibration, do not use the Z offset menu, but instead, turn the knob.
- If you cant move or cant fit the business card in between the nozzle and the bed = Turn the knob clockwise
- If you cant feel any scratching on the business card = Turn the knob counterclockwise
※ Rotating the knob by one revolution changes the height by 0.8mm.
Rotating the knob by one edge changes the height by 0.1mm
※ Please rotate ONLY the Left knob!
6. After the left side calibration is complete, move the nozzle to the right side.
Repeat step 5.
7. Usual calibration ends after step 6.
Users can print a small object to see whether the bed leveling calibration is appropriate enough for printing.
Bottom surface is wiggly → Decreases Z Offset.
* Example of printed work with Z offset of 1mm higher than the appropriate value
Bottom surface is pushed → Increase Z Offset.
* Example of printed work with Z offset 0.5mm less than the appropriate value
Appropriate Z Offset
Go through Setting - Next - Test Print - Line Test (Approximately 25 min)
※ The bed leveling becomes very sensitive when outputs are printed without a raft.
Unless under certain circumstance, please use the Raft On option when printing.
* If Advanced Mode, Check the Settings.
* Advanced Mode : Settings - Basic - Support - Bed Adhesion Type - Raft

3DWOX Desktop S/W
- Output quality could vary depending on how user positions a model on the bed.
Place the model in a position where the usage of support is minimized.
If the usage of support is necessary, place the model while considering the fact that parts touching the support would be low in printing quality.
Place the important part of the model facing up so its surface would be more precisely printed.
→ After slicingParts of the model attached to the support are low in printing quality.
If the part has a hole or boss that needs to be precisely printed, it is better to place the part standing up so it wouldn’t need a support.
A hole that needs to be precisely printed
A hole that needs to be precisely printed①Since this boss needs the support, it would be less precisely printed.
②If this part needs to be precisely printed more than the other part, make sure to place this part facing up so it wouldn't need a support.
- The less the usage of support, the better the printing quality.
If the model’s angle is within 60 degrees from the perpendicular, it can be printed stably with out the usage of support.
These parts (within 60 degrees) are stable without the usage of support.
Default settings are set to only create the support for parts of the output with larger than 60 degrees.
Change the value in the box If you want to set a support for parts with angle less than 60 degrees.
Even if the angle is large, it is still possible to print the model without the support if the model is short in length and has pillars on each side.
You can stably print the model of length up to 40 mm if there are supports on the each side of model.
2) "Line" infill is created in the shape of a line. The directions vary depending on the layer.
Therefore, it may look like a grid from the 3DWOX desktop.
Therefore, you can print the skirt (The Green line shown below) if you set the "Bed Adhesion Type" as "None".
<Print Only Follow Mesh Surface>
This option is used when a user only prints the surface of model. Since this option only prints the surface, it prints the model’s outer wall without infill and upper/bottom surfaces. When printing the outer wall, this option prints in minimum thickness about nozzle size.
This option is used when a model is only composed of surfaces and has empty internal space as shown in the pictures below. In case of models with no upper/bottom surfaces and has thin walls, it would be hard for normal slicer settings to discern the inside and outside. Therefore, it will create the g code as it in fills the inside of the model. In such a case, this option can be used to only print the outer wall of the model without any infill.
[3D model] Its internal space is empty and has opened entrance.
[When the option is selected] Printing the outer wall without infill, upper/bottom surfaces.
[When the option is unselected] If this option is unselected, it would be sliced as an infilled model as it is an opened type.
Also when the thickness of the outer wall is about 0.4 mm thin, it would be not possible to print it under regular settings. But when this option is activated, it would be possible to print the outer wall.
[3D model] When the thickness is 0.4mm, which is a size of the nozzle diameter
[When the option is selected] Can print the model although the outer wall is thin if this function is enabled
[When the option is unselected] Does not create the outer wall due to the thickness (too thin) because the creation of outer wall, inner wall, and infill are simultaneously executed.
However, we do not recommend this function when slicing a model that requires the solidity, because there is no infill and it prints with the least thickness, which results in printing the model with little solidity.
<Combination Mode A>
When this option is selected, it slices a combination of two or more different models with overlapped part or only one model with overlapped surfaces. As shown in pictures below, two overlapped models share the inside and create the g-code when they are sliced.
When surfaces of the model meet, they create a shared internal space and infill. As shown in pictures above, 2 or more models could be overlapped. Also this option could be used for a single model. For v.18.104.22.168, this option has been activated as default.
<Combination Mode B>
If you select this option and slice the model above, it starts slicing by integrating as the picture below and filling the internal empty space at the same time. When you need to print just the exterior of the model, this option enables you to slice in case the slicing cannot be initiated due to the entanglement or the overlap of the model.
<Close Open Faces>
This option is used to resolve an issue when slicing cannot be initiated due to a crack or a hole which are created when surfaces are not properly connected to each other. When you upload a model and slice, you may find that a part of the model disappears from time to time. Such phenomenon occurs due to invisible small cracks or holes, although there seems to be no problem externally. When designing the model, the model with defects may be created under a number of circumstances. For example, they can be created when they have been inconsistently scanned or when they have been improperly attached together.
The picture on the left above is a STL model of a rabbit and the picture on the right above is when the STL model is sliced. There seems to be no problem when uploading a model. However, if you initiate the slicing process, you can find that the part between the legs and the body disappears. A defect of the associated part’s data can be suspected.
When you enable this option and re-slice, you can find that the path, which has been fixed to a certain extent, has been created.
However, this feature can fix the defects such as small cracks only to a certain extent. The user may not be satisfied with the result. In the cases when the size of cracks and holes are too big, you need a program of which the user can manually modify the model.
The concept of this option is similar to ‘Close Open Faces’ option above but it is used in a case in which the gaps between surfaces of the model are bigger. When ‘Close Open Faces’ option is selected, slicer makes decision to fill in the gaps or little holes of the model, but when extensive stitching option is selected, slicer makes decision to connect a surface to another closest surface when there is two or more open surfaces in between the surfaces to be connected. The user may not be satisfied with the result so the usage is limited to the certain extent.
You may prevent the "gap" on the surface of the upper part of the printed object from forming by modifying the settings on "3DWOX desktop." However, be mindful of additional problems.
You may modify the settings by clicking "settings" after switching the mode to "Advanced Mode." The settings below may change depending on the printing or device conditions.
Basic > Filament > Flow Compensation : 130%
Advanced(1) > Speed > Travel Speed : 180mm/sec
Advanced(1) > Speed > Top/Bottom Speed : 20mm/sec
Advanced(2) > Retraction > Retraction Combing : No Skin
Printing quality may decrease when printing under the modified settings. Therefore, please reset the settings and print.(Setting > Reset Profile)
For example of Venus shape, the outline is reinforced between the infill and top of it. For FDM, there can be a gap between the boundary of leg line and top plane of Venus shape. With the skin outline, the gap of boundary line can be improved.
The following image will help understanding.
[Before applying skin outline]
The outline is not reinforced between the infill and top.
[After applying skin outline]
The outline is reinforced between the infill and top.
Aside from this bed lock function, when the print is completed, the bed is automatically lowered to the bottom and the long screw that is on the bottom of the bed holds the bed which works the same as the bed lock function so you don't have to worry about pressing the bed lock button when the print is completed.
You will be using the bed lock button when you have to reinstall the bed sheet after you cancel the print or in situations where the bed is not at the bottom of the printer.
You may remove the USB stick when the X-sign (Refer to the picture below) disappears on the screen. The bigger the size, the longer it will take for the X-sign to disappear.
[Recognizing the USB]
[USB may be removed]
There is no need to re-level the bed in between prints unless the device is substantially impacted.We recommend that you level the bed every other week if you print once or twice a day. However, there is no need to level the bed as long as the object is properly attached to the bed when printed.
The maximum speed is 200mm/s. We recommend that you print at a speed of 100mm/s or under. However, printing at a speed of 40mm/s or lower is recommended due to a noise.
