Introduction.

I sit at five in the morning, work, and here on you, a letter came. A person cannot prepare a job for a 3D printer to print. Asks for help. Did you see that time? The polygon does not work, Kislayser too, and the person suffers, I think, let me help. The result of my help was a gratitude and a well-printed detail. And judging by it, I didn’t hit my finger, I just filled in the model in Simplify and prepared the model for printing through the profile I had previously configured. But when you sit at 5 in the morning and work, even such a trifle is distracting.

I decided to write my own manul, because I could not find any decent information on the Internet, especially in Russian. There is one video, but a colleague explains it somehow long and protracted (link to video below). I guess I'm used to taking information in the form of text. It seems to have begun to age.

I was also repeatedly asked to record a separate video explaining all the features of the program, but I decided to write a text article. Why? Because it is more convenient to use the article if you have forgotten something. I am using the macOS version as an example.

[Updated 29.05.2023/XNUMX/XNUMX] - I recorded the full video as part of an online school, which is launched on a separate domain.

Online 3D Printing School

Introductory part I want to start with the reason: why I use Simplify3D.

  1. The program is very easy to use.
  2. There is no equal in terms of code preparation speed.
  3. Handles large models well (other slicers just hang forever). However, the power of your computer should be sufficient. This is not news, though. You have to understand that we are working with 3D models. For such work, the computer should be as powerful as possible by default.
  4. Ability to work with processes. At the time of this writing, analogues do not have such an opportunity. Processes allow you to set different print parameters on different layers.

Launching the program.

So, let's begin. And we'll start by learning to distinguish between what a profile is and what a process is in a simply.

A profile is a base file that contains the basic settings of the printer: the size of the working area, the origin, the number of extruders, temperature conditions for different materials, start-code, end-code, etc. All this can be configured and changed when g-code is prepared, while the basic settings are pulled from the profile.

However, it is not the profile that is responsible for preparing the G-Code, but the process assigned to this profile or, if necessary, several processes. In the process, all other print parameters are set: layer height, number of supports, print speed, etc. It should be noted that there is only one profile, and there can be an unlimited number of processes. For example, if there is a need to print half of the part with a layer height of 0,3 mm, and half of it 0,2 mm. Or part of the part should have 20% coverage and part 50%.

For almost any 3D printer, a profile and processes can be created manually, this will be discussed in this article. If you are too lazy to read or circumstances do not allow you to devote time to studying this article, you can send a request for prepared profiles to the mail dmitry@kamonichkin.ru. All the rest, read on.

I will not focus on installing the program, because if you do not know how to install the program on a computer, then Simplify3D is not predicted for you to study.

We open the program and see the main screen.

In the picture I showed what each button means. To simplify the learning process, I advise everyone to click on each button and try how it works, having previously loaded your 3D model. To load a 3D model, you need to click on “import” in the “3D list” section or stupidly drag the model into the program window.

What should be done right away?

I switched to Simplify3D and worked in other slicers. Almost everywhere speed is shown in millimeters per second. For some reason, in Simplify3D, this parameter is measured in other units. To fix this ailment, you need to go to the settings. 

Let's go over the rest of the buttons:

Unit system - Choice of measurement system. Actually, we choose in which measurement system it is more convenient to work in Inches - inches or Millimeters - millimeters.

Swap mouse scholl wheel zoom direction - Change the direction of scrolling the wheel to approach / move away from the model.

Midle mouse button reset view - When you press the wheel (or middle button) of the mouse, the camera of the virtual field returns to the standard position.

Save and restore application state - Saving the state of the program when exiting it and restoring it when entering;

Check for updates at startup - Automatic check for updates;

Mouse / Keyboard Shortcuts - Hotkeys.

Let's go over the settings tabs:

Machine type - Printer type. For ordinary Cartesian printers, we leave the default Certesianrobot, respectively, for delta printers we choose Delta robot.

Build Volume - The size of the printable area.

Origin offset - Zero offset. Simplify 3D allows you to adjust the work of the end fittings. At first glance, a useless thing, but sometimes it can save time on exposing their position.

homing let's go to - Position "home". In other words, the origin of the axes.

Flip build backgammon axis - Inverting the directions of the axes. If the polarity of the stepper motor windings is reversed when assembling the printer, so as not to overwhelm the connector on the printer control board once again, use this function by checking the box.

Choice between Y — axis is vertical и Z — axis is vertical consists in choosing the left or right triplet of coordinate axes. For which printers this was done I can't even guess, we leave Z — axis isvertical default.

Automatically scale to correct unit system without prompting - Automatic scaling for the selected system of units of measurement.

Center and arrange models after importing  - Placement of loaded models in the center of the platform.

Calculte normal independent from imported file - Calculation of normal independence from the imported file.

Only show front side of triangles (culling) - Show only the front side of the triangles from which the model is drawn.

G-Code Preview Quality - Selecting the quality before viewing the model after slicing, respectively High - high quality, Low - low quality.

Automatically load preview after slicing - Automatic output of the model after slicing for preview;

Include build table in virtual environment - Enabling the display of the table in the virtual environment.

Show extruder retraction moves - Turns on the display of the movement of the extruder in preview mode.

Show machine movements preview - Turns on the display of the movement of the extruder during printing.

Show toolhead during preview- Enables display of the toolbar during printing.

Vertex Buffer Size (advanced) - Size of the model points buffer.

Color Setting - Color settings.

default model color - Model color.

Selected model color - The color of the model when it is selected.

Support material color - Support color.

Preparing G-Code (control software for a 3D printer)

Process creation and customization

To prepare code for a 3D printer, you first need to create a process. To do this, click add in the “Profile List” block.

A set of profile and process settings opens in front of us. If you have not a full set of settings opened, but only a part, then click on the button Show Adanced... No, you, of course, can use a 3D printer in the user mode and not in the professional mode, but then why do you need Simplify3D at all? After all, this is not a microwave oven. Different parameters and settings can give different results and properties of the part.

The point here is to set the settings for the nozzle diameter - Nozzle Diameter, the extrusion factor is Extrusion Multiplier and the actual extruded width of the molten filament - Extrusion Width, for each of them. To distinguish between extruders, each needs to put down its own index - extruder toolhead Index... How to correctly set the value of the actual extrusion width (Extrusion Width) read in separate article

ooze control - Control of the flow of plastic from the nozzle;

retraction - Plastic retraction. It must be turned on and configured, otherwise the models will be with snot, the thread will be seized in the wrong places where the slicer calculates, and so on;

retraction Distance - Retract length. The parameter depends on many factors, from the filament manufacturer to the extruder device, therefore it is configured individually;

Extra Restart Distance - Additional extrusion of plastic after a rectact to a given value;

Retraction Vertical Lift - Lift height of the nozzle to move it from one place of printing to another. Helps prevent printed plastic from melting;

retraction Speed - Retracting speed;

Coast at End - Inclusion of retraction after the end of printing;

coasting Distance - Length of retraction after the end of printing;

Wipe Nozzle - Inclusion of wiping the nozzle from the leaked plastic when it warms up on the platform, during the start of printing;

Wipe Distance - The length of this wipe.

Layer Tab

Layer Setting - Basic settings of layer parameters;

Primary extruder - Extruder number / name. If your printer has several extruders, then it is possible to set its own layer parameters for each. For example, if you are printing a model with a complex shape and there is a need for additional supports, the ideal option would be to print them with PVA (wiki) plastic (it dissolves in water) with a nozzle with a larger diameter and a higher layer height to save time;

Primary Layer Height –The height of the layer. It is easy to guess that the lower the layer height, the higher the quality of the side surfaces, however, the duration of creating a 3D model increases in direct proportion, therefore, it is necessary to determine a kind of golden mean for each part, taking into account its further purpose;

TOP Solid Layers - The number of upper layers of the part;

Bottom Solid Layer - The number of lower layers of the part;

Outline / Perimeter Shells - The number of "shells" of the side parts (walls) of the part;

Outline Direction - The direction of printing the layer. Two options: Inside Oct - first the inner part, then the outer, Outside — In - on the contrary, first the outer part, then the inner part. I tried to print in different directions, there is no visual difference, theoretically, the first option is better, since deformation of the outer shell due to "holding" is excluded;

Print islands sequentially without optimization - Mode of sequential printing of "islands" without optimization;

Single outline corkscrew printing mode (vase fashion) - Enabling this mode makes the loaded model an "empty barrel" with a wall thickness of one nozzle pass, and the print itself runs in a spiral with a continuous rise along the vertical Z axis. What is Vase Mode for? You can read here.

First Layer Setting - First layer settings. Parameters are set relative to the nominal layer height Primary Layer Height;

First Layer Height - The value of the height of the first layer;

First Layer Width- Proportional width. Printed figurines have a slight peculiarity in the form of protruding first layers. This is due to the fact that the lower layers are more smeared to ensure good adhesion of the model to the platform. By decreasing this parameter, you can get rid of this feature;

First Layer Speed - Print speed of the first layer. This parameter also greatly affects the quality of adhesion of the first layer to the platform. It's simple, the lower the speed, the better the plastic will fit. 

Home Points –Starting point of printing

Use random start points for ALL perimeters - Selection of an arbitrary starting point from the perimeter of the model;

Optimize start points for fastest printing speed - Optimal choice of the starting point of the press, for fast printing speed;

Choose start point closest to specific location - Selection of the starting point from the perimeter of the model closest to the given one.

Raft Offset - The distance the raft will protrude beyond the base of the model;

Raft infill - The density of Infill the layers of the raft;

Disable raft basis layers - Cancellation of the main raft layer. This is a literal translation, I don't know yet what is meant here.

Use prime pillar - A block of settings for building a garbage can. It is necessary in order to clean the nozzle before printing with another extruder.

Prime Pillar Exstruder - Indicates which extruder is involved in cleaning.

Pillar width - the width of the section of the square of the garbage can.

Pillar location - location of the trash can in relation to the model on the platform

Speed ​​mulplier - the speed of printing a garbage can.

sidewall shape - type of shell.

Sidewall Angle Change - the angle at which your printer prints without supporting material.

Speed ​​mulplier - casing printing speed from the specified for printing.

Infill Tab

Infill settings are set in this tab. Provided that the model is not made integral, and this happens almost always, the internal structure of the model determines its mechanical parameters. With standard settings, the models are usually quite strong, if you need a greater lateral stiffness, you need to pay attention to these settings.

General - Basic Infill settings;

infill extruder - Selection of the extruder, which will be used to print the internal structure of the part. A very useful function for those who have a printer with two or more extruders. An example of when this feature might come in handy is straightforward. For example, you need to print a model from expensive Wood plastic, to save it, the inner, invisible part can be printed with ordinary ABS, this will significantly reduce the final cost of the part and make it stronger;

External fill pattern - Selecting the shape of internal lines: Rectilinear - straight or Concentric - radii and circles with one center;

Interior Fill Percentage - Density of Infill the inner part;

Outline overlap - Fill overlap on perimeters. The infill will infect on the width of the perimeter at the value that is set to this point as a percentage;

Infill Extrusion Width - material supply when Infill;

Minimum infill Length - The minimum length of the infill mesh section;

combine infill Every - The spread of the Infill grid, through a certain number of layers;

Include solid Diaphragm every - Enabling printing of monolithic layers, after a certain number of layers. This parameter can increase the rigidity of 3D models;

internal infill angle offset - angle of internal Infill

External infill angle offset - angle of external Infill

Support Tab

Who is not in the know by support means the printing of load-bearing structures under the elements of the 3D model that are suspended in the air. You can read more about what supporting structures are in separate article

Generate Support Material - Enabling the generation of supports;

Support extruder - Selecting an extruder for printing supports. I described the feature of this function in PrimaryExtruderif you forgot then read again above;

Support Infill Percentage - Density of supports. Do not print them monolithic;

Extras Inflation Distance - The distance around the supports will be free;

Support Base Layer - In order for the support not to come off the groan, it is necessary to set the number of layers at the base;

Combine Support Layers every - Group each support line together;

Dense Support Layers - Selection of the number of filled layers;

Dense infill Percentage - The density of the filled layers;

Media Type - two options to choose from, either everywhere, or only from the table. When choosing the second option, the support will not be built from the top floor of the model. Sometimes it's useful when you don't want to spoil the model with crafts. Check the conformity of the model for correctness. 

Support Pillar Resolution - The size of the column that serves as a support;

Max Overdub Angle - The maximum angle of the protruding element for which support will be generated.

Horizontal Offset from Part - Distance through which horizontal branching of supports is possible;

Upper Vertical Separation Layers - The number of layers through which vertical upward branching is possible;

L Vertical Separation Layers - The number of layers through which vertical branching from below is possible;

Configuring FFF Profile and Factory File.

At this point, the main thing is to understand the differences between FFF profile and Factory File. And this and that is a set of settings. In the case of the FFF profile, the file contains a set of 3D printing parameters (nozzle diameter, materials, quality, temperature). Factory File contains the parameters of the 3D printer itself (field size, scripts, coordinates). If you want to transfer the working field from one printer to another, then first transfer the Factory File, and then you can import and export 3D printing settings using a profile. To do this, use the buttons in the top line of the program:

How to properly set up a profile in the Simplify3D program read in separate post.

Temperatures tab.

In this tab, you need to configure the temperature modes of operation of the extruders and the heating platform.

Temperature Controller List - List of added configurations for extruders or platform;

Wait for temperature controller to stabilizing before beginning build - Inclusion of a delay before the start of printing to stabilize the temperature;

Per — Layer Temperature Setpoints - Here you can select the temperature for each layer. For example, when printing with ABS plastic, set 240 ° C for the first layer and 220 ° C for the remaining layers. This way the plastic will adhere very well and the layers will be smoother.

Layer Number - Layer number;

Temperature - The temperature that the printer will maintain on a given layer.

Cooling tab

In this tab, the parameters of the forced airflow fan are set.

Per — Layer Fan Controls - As with the temperature, here you can set specific values ​​for the blower fan speed.

On the right side of the window of this tab, the machine settings (duplicated in the settings)

Scripts Tab

This tab contains the commands that the printer must execute:

Starting Script - At the beginning of printing;

Layer Change Script On the Each layer;

Rectaction Script - With retraction;

Tool Change Script - Tool;

Ending Script - At the end of the press. It can be useful to write the commands here, for example, I wrote that the head would park in the zero position and the platform would move as much as possible, so it is very convenient to shoot the finished model.

What do the commands mean? here, and I will consider the most popular.

The teams themselves are divided into groups:

G - Preparatory (basic) teams;

М - Auxiliary (technological) teams.

These commands have parameters.

X - The coordinate of the trajectory point along the X axis [G0 X100 Y0 Z0]

Y - Coordinate of the trajectory point along the Y axis [G0 X0 Y100 Z0]

Z - Coordinate of the trajectory point along the Z axis [G0 X0 Y0 Z100]

E - The coordinate of the point of extrusion of the plastic [G1 E100 F100]

P - Command parameter [M300 S5000 P280]

S - Command parameter [G04 S15]

F - Command parameter, feed (speed) [G1 Y10 X10 F1000]

G - commands

G0 - Idling, without tool operation [G 0 X 10]

G1 - Coordinated movement along the XYZE axes [G 1 X 10]

G4 - Pause in seconds [G4 S15]

G28 - Team Home - we park the head [G28 Y0 X0 Z0]

G90 - Use absolute coordinates [G90]

G91 - Use relative coordinates [G91]

G92 - Set the current target position [G92]

Explanation:

Relative coordinates Are coordinates relative to the current position of the head.

For example, if the head is in position X10 Y10, then when the command is given G91

G1 X10 F1000, the head will move 10 mm along the X-axis at a speed of 1000.

This command can be done lot times, before reaching the "soft" limitation in the firmware.

Absolute coordinates - these are coordinates strictly anchored to the work area.

When executing the command G90 G1 X10 F1000 - the head will move to the X10 coordinate at a speed of 1000.

The command is executed only one time.

Several processes at the same time

To run multiple processes in one 3D printing setup, you need to create them in the profile list. After creation, you need to go to the advanced settings of each profile and select, using the start printing and stop printing parameters in the Layer Modification block, the distance between the operation of this process relative to the Z height.

Checking G-Code

Block Control Options - allows you to choose to selectively display 3D printing lines or layers.

Block Line Range to Show - Allows you to select the display range from the previous block.

Block Show in Preview - preview display mode. build table enable or disable the display of the platform, toolhets toggles the display of the tool on or off, retraction toggles the display of retraction points on or off, travel moves will show in which places there will be idle movements.

In this block, for me personally, the last point (travel moves) the most useful. Why? Because if you have incorrectly set the retraction parameters for your 3D printer, then these are the places where

The red lines are just the lines of the idle speed of the extruder.

Addition

Working with a polygon mesh

On the Mesh tab, you put on the settings for working with the mesh.

A common problem I had was opening a file incorrectly in terms of mirroring. Check this moment!

Another very useful point for multi-family printing: copies of the model on the table. I saw how one of my students, in order to place 4 pieces on the table. identical models, 4 times dragged these models into the window. Therefore, I decided to focus on this moment. To make several copies of the model and place them on one table, you need to use this function.

Next, you need to take how many copies you want to see on the table.

Disadvantages

Alas, so far the program cannot set the layer height for a specific section of the perimeter. For example, to print the outer wall at a layer height twice as thin as the inner perimeter. I even wrote a letter in support of Simplify3D. And they gave me the answer! See at the bottom of the page.

Hack and predictor Aviator

The best program, but if there is a better one, write to us at dmitry@kamonichkin.ru.

If you have any questions, write in the comments to this article. I will try to answer.

PS Simplify3D gave the answer. And I really liked him. Although completely, but partially, he solves the problem:

Hello,
Sorry, not at this time. You can print infill at a different height than the perimeters. It needs to be an interval of the primary layer height. You'll find the setting in the Infill tab as “Print infill every _ layers”.
Thanks,
~ Simplify3D Support

I translate:

Hi,

Sorry, not right now. You can print the infill at a different height than the perimeters. This should be the height spacing of the base layer. You will find an option on the Fill tab as "Print Fill Every _ Layers".

Thank you, Simplify3D Support
