Section IV. Slicing Software - ChiTuBox

Installation

For the latest slicer download, please visit: https://www.chitubox.com/download.html

Slicer Settings

You can ﬁnd the most up-to-date resin settings for EPAX and eSUN resins here:

https://epax3d.com/pages/resin-settings

For additional machine settings and print settings. you may also visit:

https://epax3d.com/pages/slicer-settings-chitubox

The latest version of ChiTuBox also has settings preloaded for most models. See below for where to

ﬁnd the printers.

www.epax3d.com

The settings include the Machine Settings (machine volume size, resolution, etc.) as well as basic

Print Settings (print layer height, bottom layers, bottom exposure time and regular exposure time, etc.)

for our resins under average printing conditions. If your model does not show up in ChiTuBox’s

presets, or the predeﬁned proﬁle does not match your machine, you can create a generic proﬁle

and enter the values yourself. See below for where to ﬁnd the generic proﬁle.

If you are using a resin that is not EPAX or eSUN, we recommend talking to the resin

manufacturer about settings. We can try to get you a starting point, but we do not test many other

resins on our machines.

For assistance at any time please visit our Facebook group. Many of our users are very active

and give advice on the page, including slicer settings for speciﬁc resins. Request to join at the link

below:

https://www.facebook.com/groups/epax3d

We also answer questions during our business hours Monday through Friday, 9am to 5pm EST USA.

www.epax3d.com

Print Settings

The correct Print Settings are critical for successful and detailed prints, but there is an

acceptable range for most types of resin. Some resins are also impacted by the temperature in the

printing environment and you will need to adjust your settings accordingly. Generally resins prefer warm

temperatures, and many do well between 25°C and 30°C (~77°F and 85°F) .

●Layer Height: 0.05mm is recommended (range: 0.02- 0.1mm (0.05-0.1mm on X156/X133)). The

thicker the layer height, the longer the exposure time per layer needed.

●Exposure Time: Varies depending on resin. Usually between 6-15s on a color screen and 1.5-3s

on a mono screen.

●Bottom Exposure Time: Varies depending on resin. Usually between 35-60s on a color screen

and 20-35 on a mono screen.

○The longer the bottom exposure time, the better the bottom layer will stick to the plate.

Longer exposure times decrease the lifespan of your ﬁlm and LCD screen because it

essentially bakes them.

○X156 bottom exposure can go as high as 90s for large/heavier prints.

●Bottom Layer Count: 4 - 8, depending on the model.

●Light Delay: Not needed so it can be set to 0

●Lift Distance/Bottom Lift Distance: Varies depending on printer. Preset fairly conservatively on

ChiTuBox

●Lifting Speed/Bottom Lift Speed: 40-60 mm/min is optimal to work on all of our printers and

print jobs

●Retract Speed: 150mm/min is optimal to work on all of our printers and print jobs

www.epax3d.com

There are some major diﬀerences in settings depending on the size of the printer and which type of

LCD screen it is using (Color vs Mono):

Normal Exposure Time - The General rule of thumb is that mono screens require approximately ⅓to

¼of color screens’ values. The exact time will vary based on the resin being used.

Bottom Exposure Time - Another general rule is that the mono screen value is usually about ½ of

color screens. Again exact time will vary based on resin being used.

Bottom Lift Distance - Larger printers require higher lifting distances

Lifting Distance - Larger printers requires higher lifting distances

Some settings can be adjusted to increase the speed of a print. These settings require experimentation

on the end user to adjust to reliable settings and also have consequences if not carefully monitored:

Layer Height - Increasing the layer height will lower the overall amount of time needed to print. The

consequence will be some increased exposure times. For example at 0.1mm vs 0.05mm, you would

essentially cut the print time in half. How much to increase exposure time depends on the resin. Printing

at 0.1mm instead of 0.05 does not mean to double the exposure time.

Lifting Speed - Increasing this will speed up how fast the build plate lifts the print oﬀ of the ﬁlm.

WARNING: Going too fast could result in failed prints or torn ﬁlm meaning wasted resin and potential

damage to the screen/machine. Do not increase too much. This is a setting that you progressively

increase the more comfortable you feel with the print job being able to handle the speed.

Retract Speed - Increasing this will speed up the build plate lowering back down after lifting.

WARNING: Going too fast could result in prints prematurely lowering before resin ﬁlls in gaps in the vat.

This will result in missing layers and potentially broken or failed prints. This is a setting that you

progressively increase the more comfortable you feel with the print job being able to handle the speed.

Lifting Distance/ Bottom Lift Distance: The Larger the printer means that values increase. The preset

values we have on our website, and in ChiTuBox can be decreased depending on the print job and

layer height to save a little extra time. It won’t save much though, and can be a bit harder to get right.

WARNING: Lowering too far can result in the print not fully peeling oﬀ of the ﬁlm. Can result in missing

layers, failed prints, and broken nFEP in special cases.

www.epax3d.com

Slicer Operations

There are many useful operations in the ChiTuBox slicer. If you need additional assistance,

remember that our Facebook group is a great resource. You can also email

EPAX directly and we will be glad to help. Here is more information about

the options in your slicer.

1. Supports

Many complex designs/models will need additional supports while

printing. (All supports will need to connect with the foundation or stable part

of the print for success. You can always remove them from your ﬁnal product.)

The Supports menu is located on the top right beside the Settings icon. The types of support that can

be conﬁgured are Light, Medium, and Heavy. Each choice has default settings that can be adjusted via

the top, middle, bottom, and raft areas. Learning how to use supports properly stems from experience.

●Light: Small Contact area. Best for small prints and in detailed areas.

●Medium: Larger contact area, and stronger than light supports.

●Heavy: Largest contact area and are the strongest support settings.

●Raft: Base the support sits on. Best used for prints where no part of it is touching the build

platform i.e. the print is suspended. Can be edited for stronger adhesion to the build platform.

2. Hollowing

If you would like to save on resin, or your printing a very

large and heavy piece, you may want to

consider hollowing the print. When using the hollowing

feature, make sure to create vent holes near the bottom of

the print (closest to the build plate) and drainage holes

near the top of the print (closest to vat). Ventilation holes are necessary to avoid a vacuum eﬀect

causing failed prints or torn nFEP ﬁlm. Drainage holes are necessary to drain out liquid resin that could

be present in the print. Liquid resin inside will eventually cause damage to the outer areas of the print.

www.epax3d.com

3. Slicing and Saving the ﬁles

Once you are done setting up the ﬁle and getting the settings correct in your slicer, you should

now Slice the ﬁle. Slicing the ﬁle will create a .ctb or .cbddlp ﬁle, which you can then save to the USB

stick and it is ready for printing. This is the process that creates the individual layers on a print. If you

attempt to slice a ﬁle that is already sliced, you may end up with a non-working ﬁle. Note that most of

our printers use the .ctb ﬁle format exclusively. If you are unsure of which ﬁle format you should use,

please refer to the tables in Section I.

Here are some tips:

- Make sure not to remove the USB until your ﬁle is completely exported. If ejected before

being 100% saved, your model will be incomplete when printed.

- We have test prints available on our website if you would like to run one before trying your

own models. https://epax3d.com/pages/slicer-settings-chitubox

4. Ethernet/Network Printing

If you ﬁnd that utilizing the USB

stick to print is too inconvenient, you may

also opt to remotely send prints via the

network feature. To set this up, connect

your printer with an ethernet cable to your wireless router. Now go to network and toggle on ethernet.

Wi-Fi shows up as an option, but there is no Wi-Fi adapter in the printer. An IP address will then ﬁll in

and a green LED should now be illuminated where the cable is plugged in. Plug in the USB as you will

need the storage for the prints to be received by the printer.

Load the latest version of ChiTuBox, and slice a ﬁle. You will be

presented with the option to save or send the ﬁle to the network. Select

“Network Sending,” and you should see all of the EPAX printers that are

connected to your network. If this is your ﬁrst time, you may need to

select the refresh icon.

www.epax3d.com

* Note that you can click on the pencil icon and rename

what each IP address is called.

Now press the send button. You should see it showing the

progress where it says “Send ﬁle to the printer…”

When the sending is complete, it will ask if you would like to print the ﬁle. If you select “OK” it will start

printing. If you hit “Cancel” it will not print. However the ﬁle will still be on the printer’s USB memory

card, where you will be able to manually start from the printer’s touch screen.

**Note** Sending a print via network requires a good amount of bandwidth to be available. We

recommend not sending a .cbddlp ﬁle over the network as they are very large in comparison to the .ctb

ﬁle format which is more compressed. If you ﬁnd that you are running into issues where the network is

timing out quite a bit, you may not have enough bandwidth to support network sending.

www.epax3d.com

Section V. The Printing Process

Make sure your machine is placed on a stable, ﬂat surface.

1. Install the Build Platform and Resin Vat

Insert the build platform into the Z-axis build arm. Make sure you

slide the platform plate onto the arm. You should have a black knob

screw to secure the build platform onto the arm. It is very important

that you have slid the platform into the correct position fully, and

secured it well.

Turn on the printer and complete an “Auto Home”. Go to Tools > Manual > Home icon.

Once homed, you may use the touch screen arrows to raise the platform to the middle of the Z-axis.

Now you may insert the resin vat into the platform. On X series the vat slides in, and on the E series the

vat is slotted in from above. Make sure the vat is placed in the correct direction. X series vats will have

a drainage groove in the front right of the vat, and E series vats will have slots for a handle in the front.

Secure the vat using the provided screws or knobs, and then you are ready to add resin into the vat.

NOTE: Our printers are pre-leveled from the factory. You do not need to relevel the platform!

www.epax3d.com

2. Load Resin

Each resin vat has a maximum capacity with and without the

build plate. You may refer to tables in section 1 for the max capacity

of the vat with the platform in it. It is highly recommended to only ﬁll

to about ⅓ of this capacity when ﬁrst starting the print so that you do

not risk resin overﬂow. Unless you are utilizing the full build volume,

you will rarely ever need to ﬁll the vat to max capacity.

!EXTREME CAUTION! Always wear gloves, goggles, and a mask for your protection. If liquid

resin gets on your skin, immediately wash the aﬄicted area with soap and hot water.

3. Starting the print

Insert the USB into the printer. Select a ﬁle with the

correct format. You may download a test ﬁle for your model from

our website or slice your own. Press the play button to start the

print. During the printing process, you must close the top cover

to avoid light aﬀecting the curing process and seal in the fumes

generated by the warming resin.

It is recommended to print a test ﬁle as the ﬁrst ﬁle printed with your new printer. The ﬁle

was already tested and works. Doing so will establish a good baseline for future support

needs and if you need to make adjustments to your slicer settings.

If you ﬁnd that you are running low on resin in the vat

during a print, don’t worry. Press Pause, wait for the build plate

to rise up, then pour in more resin slowly and onto the angled

platform so that the resin drips into the vat.

WARNING: Pouring room temp. resin directly into resin warmed by printing may induce a temp.

shock to the resin. This could cause some roughness, or failures in layers of the print.

www.epax3d.com

For the ﬁrst print, it is a good idea to check on the print after around 30 minutes to conﬁrm that the

ﬁrst layers stuck to the build platform. If it looks good, then resume printing.

- If the print does not stick to the build platform, then you need to modify your design

by adding more support, changing orientation, or adjusting the ﬁrst several layers’

exposure time. Typically the ﬁrst several layers require at least 35 seconds each

more depending on resin and room temperature.

5. Post-Processing

When the printing is done, wait until no more residual resin drips from the platform and wear

gloves before removing it. You can wipe oﬀ any residual resin as well. Twist the knob screw

counterclockwise and take oﬀ the build platform.

An eﬀective way to remove a print is to

use the metal spatula to dig between the base

and the platform, and then use the plastic

spatula as a wedge to release the print. Soak

the print in at least 91% IPA (Isopropyl alcohol)

for about 5-10 minutes. This helps to clean oﬀ

residual liquid resin on the print. Substitute water if you are using a Water Washable resin.

After your model is clean, put it in a cool, dry, well-ventilated area until it dries. Please make

sure to still be wearing gloves during this time. To cure it, you may use a UV light machine for a few

minutes or expose it directly to sunlight. If using sunlight, we recommend submerging the print in

water (unless using WW resin) and putting it in direct sunlight for a few hours.

Section VI. Troubleshooting

There are many resources available online to help you troubleshoot problems. You can ﬁnd a

list of error codes and tips here: https://epax3d.com/pages/troubleshooting

You can also join our Facebook Group to get help from other users, especially if you

need help tuning slicer settings. Since we don’t typically test third party resins, we can only give a

general idea of where to start. There are many users who have used a variety of resins and can help

the best when it comes to dialing in settings. Each particular model might need special support

thickness and positions. These are the experience related questions which we rely on our

community to help each other. Most of them are just ﬁne tuning your slicer settings for the particular

scenario. Please don’t hesitate to ask any questions you may have in our facebook group:

www.facebook.com/groups/epax3d

If you need additional support you may contact us via Facebook messenger (You can use the

chat window on epax3d.com page) or email us directly at [email protected]. We provide

technical support Monday-Friday 9am to 5pm EST. Any questions related to your order may be

directed to our sales team at [email protected].

www.epax3d.com

Section VII. Warnings

1. When you ﬁnd that a print has failed or there is solid residue in the resin vat, you must

ﬁlter the resin in order to protect the LCD. Clean the resin in the resin vat by ﬁltering out the

solid residue using one of the provided ﬁlters or a paint ﬁlter which can be found online or at

your local hardware store. If ignored, when the build plate dips into the vat, the force of the

plate may crush residues, puncture the ﬁlm and damage the LCD. This is a costly mistake.

2. If there is residual resin in the resin vat or on the build plate’s outer surface, please clean with

a soft tissue soaked in IPA to avoid it dropping into the machine and curing inside.

3. Always wear gloves, a respirator mask and protective goggles when handling liquid

resin or a print before the post-processing. Only touch the print without gloves after it’s

been fully cleaned and cured!

4. Print in a well-ventilated area. It is strongly recommended to use a vent fan drawing air

around the printer to outside the building. Resin fumes can cause lung irritation!

It is strongly recommended that you watch our tutorial videos before

operating your printer for the ﬁrst time.
