Whereas 3D printers using the same technology and marketed for about the same price usually do not vary much(theoretically) in terms of print quality, the results of post-processing can vary greatly depending on your expertise and skills. Simply put, you take either 100 percent blame or credit for your finished 3D prints.

So, what processes are involved in post-processing?

•Cleaning

In FDM, cleaning usually means to remove support structures from the object.

As we know, there are two types of support material: soluble and insoluble. Insoluble material is relatively strong and can only be removed with a spatula,knife or sheer brute force,leaving the model and print platform vulnerable from possible damage.

If you are lucky enough to own a dual extrusion setup, you may want to use soluble material for your supports. Soluble materials such as HIPS and PVA, can be dissolved in water or Limonene.

Check out our previous blog on how set up your 2 extruder 3D printer.

•Fixing

One way to circumvent supports is to have your model printed separately. This means you will have to manually attach together your parts. ABS prints can be welded or glued together using acetone. Here is a tip you should heed: when creating joints or keys for a model, make sure to create joining features large enough for the 3D printer to create them cleanly. Thumb of rule is that features should be larger than 4-5mm in diameter. Glued components should be secured together using rubber bands, and cyanoacrylate glue should be used to spot glue around the connecting areas. If seams are rough or have gaps, bondo or filler can be used to smoothen them.

•Surface finishing

Sanding

Layer lines are the bane of models printed using FDM technology. Carefully sanding the surface of the model with paper should get rid of the lines. This process requires delicate skills and great attention. Start with higher grit to lower as you go. Do not sand in one place for too long as friction-generated heat could melt the material. The downside to manual sanding is inconsistent results, as well as being laborious.

Smoothing

To give the print a glossy finish, chemicals are sometimes used. For example, Acetone and THF are used to smoothen the surfaces of objects printed with PLA and ABS. The problem with this technique is that it can not be controlled: sometimes features are melted off that should remain. On top of that, vapours can be harmful when inhaled.This can be avoided using closed chemical cleaning machines.

•Coloring

Coating and Painting

Surface finishing is often followed by painting. Parts need colouring would ideally be printed using white material. A layer of primer is usually applied before the model is painted,followed by another stage of sanding. Painting is usually done manually using a brush or spray(at an arms length). It is highly recommended that you hang the object in an open, dust-free,well ventilated space. This will allow you to paint all surfaces evenly without having to handle the model while paint is drying. The painted object should be ready to polish after 1-2 days.

Before reading this article, please make sure you have already read the setup guide of the version of the 13B single extruder and that you are able to use it to print 3D models. If not, please learn how to operate the single extruder. Of course, you can take this one as the single extruder version to get started.

Step 1

Open Repetier Host, and click Config/Printer Settings to set up the connection.

1. Name your printer.

2. Select the corresponding COM port and baud rate. The baud rate is generally 115200 or 250000.

3. If you are not sure about the COM port, you can check it in your device manager.

Step 2

Set up your extruder

1. Choose the number of extruders, here we choose
2. Select the diameter and color of the filament
3. Offset X/Y refers to the distance between the two extruders, which can be adjusted based on real situations. You can leave it alone now.

Step 3

Set up the shape of the printer

Choose Classic printer as the printer type.

Home X: min Home Y: min Home Z: min

Print height: 150

Now you can click the Connection button on the left corner to check whether it can connect with your printer. If it fails, please recheck the COM port and Baud rate.

Step 4

Manual control

1. X home

Click X home to home the X axis, or you can click the right/left arrow to move the axis to check whether the direction and distance are correct or not；

2. Check Y axis and Z axis respectively in the same way

3. Click the icon of the heated bed on RH to heat the bed. observe whether the temperature is rising to a pre-set value

4. Click the icon of the heated bed and extruder, observe whether it is heating up to the pre-set temperature, and keep it at that value

5. When the temperature for the extruder surpasses 170 °C , choose extruder1 and extruder2 respectively, you can move them and check their directions

Step 5

Leveling the two extruders.

Leveling the two extruders is very important if you want to print with two extruders at the same time.

First, you can adjust one extruder to make it parallel with the surface of the heated bed (the same way you level for a single extruder setup), click the button of Z home to adjust the distance between the nozzle and the heated bed, make sure the vertical distances of the nozzle to the four corners of the bed are the same.

After that, tweak the distance between the second extruder and the heated bed by adjusting the screws, as shown in the following picture: Loose the screws, and then you can move on to get the right distance between the two extruders and the heated bed.

you may need to repeat this step to get it all right.

But it’s worth it. Once you get it done correctly, you won’t need to do it again.

The settings mentioned above are on Repetier Host, which only involves the control of the 3D printer and the preview of the model.

All the settings do not concern the print result but the slicing. So we will continue with the slicing setting. The slicer is independent of Repetier Host. So, should we set up the slicer now? Take it easy. Let’s see whether our printer can run normally.

Step 6

If the printer goes well. We can go on with the slicing. First, let’s get a quick view of the slicer.

RepetierHost supports many slicers, with Slic3r and CuraEngine being the most popular; Slic3r is more powerful in terms of functionality, but CuraEngine comes with more optimized slice velocity.

You can choose a slicer here. Upon selecting the slicer, please click Configuration.RepetierHost will bring up a wizard of the corresponding slicer that will walk you through the configuration.

Here we take Slic3r as a demonstration. As to the configuration in CuraEngine, we will pick it up in the follow-up study in our forum www.geeetech.com/forum/, so, please stay tuned. If you are experienced in CuraEngine, we would appreciate it if you could.ld share your insights with us.

Next, download the file:two_color_cube.zip, unzip the file, and save it somewhere. You will need it later.

Step 7

Click Configuration， open Slic3r

Step 8

We have prepared a set of parameters for I3B_2E dual extruder, that is, I3B_2E_config_bundle.ini. You will need to import those parameters to slic3r from here.

In Slic3r, under file> Load Config Bundle.. navigate to the folder we just downloaded and unzipped, open I3B_2E_config_bundle.ini,

Step 9

After loading, you can find the option of Geeetech_I3B_2E in the drop-down menu.

In my case, I use the Geeetech pro-C model,(I refer to the I3B_2E in this article)， the extruder is MK8(1.75cm-0.4mm)， PLA filament, so we choose Geee_I3B_2E, PLA 1.75mm, and Geeetech_I3B_2E respectively.

All the parameters you set can be saved in RepetierHost for future reference.

Step 10

Unzip two_color_cube.zip， click Load to import the .stl files，choose two_color_cube_1.stl and two_color_cube_2.stl respectively.

Actually, two_color_cube is composed of two .stl files. each printed by one nozzle.

After loading, you can preview it. The two files are separated. Now you need to adjust the locations to combine them together.

Select Object Group 2 and click center, then Object Group 1 and center. Now the two models are combined as one.

Assign printing tasks for both extruders respectively.

Step 11: Slice

If this warning pops up, choose NO

G-code is generated successfully

Step 12: you can print directly via serial port (USB connector）or save the G-code to an SD card, and print stand-alone.

Step 13′: The end

Need an advanced and colorful challenge? Here are 35 free dual extrusion models specially designed for your dual extruder 3D printer.

3D printing is a fun hobby, and one that you can make as simple or as complicated as you like. Making stuff in a single material, for example, is pretty much the standard option for most 3D printers and projects. But what if you wanted to print something in more than one material? This is where a dual extruder 3D printer comes in handy.

What’s a dual extruder 3D printer? It’s an evolution of the Fused Filament Fabrication (FFF) technology, where instead of one hot-end extruding molten thermoplastic filament, it has two hot-ends with two separate spools of filament. Therefore, it becomes possible to print off objects in two colors or two materials (or both).

It’s also a useful technique for fabricating objects with complex geometry. Using a secondary dissolvable material, you can create removable supports for those tricky overhangs and bridges that single extruder 3D printers can’t handle.

In software terms, “dualstrusion” works by overlaying two separate (but interlocking) models on top of each other in the same physical space, and the slicing software issues commands to the 3D printer to distinguish between them when printing the object.

Current dual extruder 3D printers on the market include the Ultimaker 3, BCN3D Sigma, Makerbot Replicator 2X, Printrbot Plus and Flashforge Creator Pro. Some manufacturers go even further, and offer machines capable of triple and evenquadruple extrusion!

But let’s not get too far ahead of ourselves. Here’s a list of models that are just perfect for dual extruder 3D printers. Master these objects, and you are truly on the path to becoming a true 3D printing guru.

Dual Extruder 3D Printer Models #1: Low-Poly Pokemon

According to designer extraordinaire Flowalistik, Pokemon and 3D printing have something in common: they both evolve. The multi and dual extrusion Low-Poly Pikachu is designed to show all the possibilities of dual and multi extrusion 3D Printers. This model is more complex but easier to print, and it keeps all the features from the original design: it doesn’t need support material, infill or prime tower. There are three more in the series: Squirtle, Bulbasaur, and Charmander.

Dual Extruder 3D Printer Models #10: OpenRC Experimental Wheel

The Open R/C Formula 1 project is a great initiative by maker Daniel Noree, who’s shared his open source blueprints for a 3D printed radio controlled car. The most critical component of any car — radio-controlled or otherwise — are the wheels. Which is why Noree has been experimenting with printing the wheels using a dual extruder: flexible rubber for the tires, plus solid ABS for the rims. The model is still at an experimental stage, however!
