Velleman K8200 3D Printer Kit. Printer Setup and Callibration


By Ben Lopez
Description: Legacy Velleman K8200 3D Printer
Assembly Time: 32 hours
Skill Level: Intermediate

Recommended Items:
Filament
Precision Blade
Screwdriver
Washer

Last month, I wrote about the challenges and lessons I learned from Building the Velleman K8200 3D Printer Kit. As it turns out, the setup and calibration was way more fun than the build.

The printer can be a bit rough around the edges, but by the time you have everything tuned the way you like it, you will have learned a great deal about how your machine works. The Velleman K8200 3D printer has very customizable settings, with the trade off that they are not all changeable within the provided easy-to-use interface.

3D printers take a 3D model, usually an .stl file, and use "slicer" software to divide the model into printable layers. From there, a g-code is constructed to command the printer to execute the geometric movements (x, y, z axis) necessary to print the part. The supported software, Repetier, is a nice, free interface that handles the g-code for you. Repetier also handles the slicer software pretty well within the same interface, making the process relatively user-friendly.

The kit's instruction manual will give you the correct settings to use for your first print, which are not default settings. All of the other settings must be changed in a separate file meant to specify your printing material. This file is essentially a text file that the printer will use for parameters such as the fill density, infill shapes and number of shell layers.

You start the calibration by tuning the motors to a standard voltage – but there was a step left out of the instructions about when to plug in the power cord. Remember to plug in the power cord just before tuning the motors, because you will not get correct readings or enough power from just the USB connection.


The Troublesome Switch

I began to calibrate the printer bed and all of its "home" positions on the x-, y- and z-axis when I encountered a small clearance issue. The black home switch pictured was blocking the extruder assembly from reaching the bottom of its range and activating the switch.

An easy fix with a washer

When I hit the z-axis home button in Repetier, the assembly ran into the switch housing and caused a very loud vibration as the motor kept trying to turn but could not. While I tried to figure out what was going on, a couple of co-workers walked into the room to see if I had broken something. I used a washer to resolve this clearance issue and was back in business. Aside from embarrassing myself, there were no other problems caused by the clearance issue.

The next step before printing your first part is to feed your filament through the extruder. I recommend purchasing your own filament as you will likely want to start testing out what your printer can do and maybe try out more than one color. Once you get your full-sized spool primed as per the instructions, you are ready to print!


The first two prints!

Your first print will let you know what to adjust in your printer profile text file. In our case, we could tell we needed to increase the filament retraction because PLA filament was unintentionally dripping when the extruder was moving between sections where it actually needed to lay down material (as can be seen between the Christmas tree branches). The extra material on the first print was cleaned up a bit with a precision blade. Each of these tree halves were printed in about 20 minutes and without bugging any of my co-workers in the other room. This printer is surprisingly quiet, even with the fan turned on all the way.

Now that you know what to expect from the build, calibration and printing.

Ben earned his bachelor's degree in Mechanical Engineering from UC San Diego, where he learned about robotics andelectric vehicles. His interests include innovative technology, music, tools and anything automotive.

Top 20 Free 3D Printing & 3D Printing Software

Looking for 3D printing software? We've rounded up the top 20 software tools for beginners and professionals alike. Most slicers are free.

What is a slicer? This is a program for preparing a digital model for printing. Models for 3D printing are usually distributed in STL files. To turn an STL file into G-code (a language that a 3D printer understands), a slicer program is required. It is called a slicer because it cuts (to slice - English) a 3D model into many flat two-dimensional layers, from which a 3D printer will add a physical object.

Which slicer should I choose? In this article, we will tell you which slicer is best for 3D printing for each stage of your work. Which one is better for preparing a 3D model for printing? But what if you need to create a 3D model from scratch? And if you are only taking the first steps in 3D?

Don't be afraid: we've answered all of these questions, including the required skill level for each program and where you can download it. The great thing is that most of these programs are completely free and open source.

INTRODUCTION

Now our country, like the whole world, is entering the period of the sixth technological order. In the sixth technological order, artificial intelligence systems, global information networks, etc. will develop. During this period, complex products will be created using flexible robotization and production automation technologies (digital production). Under these conditions, the use of traditional modeling methods loses economic feasibility, there is a modernization of known and the creation of new technological processes. Preference will be given to mathematical modeling, which, already in the process of development, will allow modeling not only manufacturing, but also all stages of operation up to disposal.

In this technological mode, production will take place in the so-called digital factories that produce small-scale products and are able to create products for specific requirements, up to single copies.

In developed countries, they already produce products at similar enterprises, exchanging data with each other electronically. Employees in one place in Russia or the world work, turning their ideas into design documentation, for example, into 3D models, and send information by e-mail from the laboratory to such a digital factory, which allows them to manufacture the necessary products.

Thus, the concept of a digital factory allows you to create the required products where and when they are needed. Placing a digital factory near the consumer will optimize logistics and reduce resource and time costs for the production of products in various industries.

Great hopes are placed on additive technologies for obtaining parts for machines and mechanisms. For the manufacture of parts from thermoplastic low-melting materials and compositions, this method has proven its progressiveness and economic feasibility.

However, for materials with a high melting point, it is necessary to consider the feasibility of using additive technologies for manufacturing parts from metals and ceramics. IN 1 /

The following parameters are listed as disadvantages:

Low productivity of the process 1 ... 1.5 cm3/h.

The maximum dimensions of manufactured parts, as a rule, do not exceed 300 x 350 x 300 mm.

High surface roughness Ra 6-12 µm (without post-processing).

Large internal stresses in manufactured parts (without the use of post-processing processes).

At the same time, additive technologies can be applied to traditional technologies for manufacturing parts from metals and ceramics, for example, for making models for investment casting, slip casting, etc.

2.GOALS AND OBJECTIVES OF THE WORK

1. The study of modern technologies in terms of the application of digital technologies

2. The study of traditional technologies on the example of investment casting (burned out) models.

3. Learning how to create a 3D model, devices and principles of operation of a 3D scanner and 3D printer

4. Creation of a casting using 3D technologies.

3. TRADITIONAL CASTING TECHNOLOGIES

Additive technologies do not always have an advantage over traditional technologies in terms of productivity, economics, and part properties. At the same time, additive technologies are necessary to optimize technology in various branches of technology, in particular for foundry production.

APPENDIX 1 shows a diagram of the traditional casting technology.

One of the most widely used and most accurate casting methods is investment casting.

In the technology of casting metals and alloys by burnt/smelted models, a model of the future product is first made from the appropriate material. As a material for the manufacture of investment models, wax or its mixtures with paraffin, stearin are used, and for burnt models, materials that burn in air with little smoke and ash are used.

Burnt-out/lost-wax casting is used to cast both artistic products and machine parts. The master model is made both by hand carving and on processing machines. This model is poured into silicone. After polymerization, the rubber part is cut and the master model is removed from it. Wax is poured into the resulting form. The extracted stencils are used in the manufacture of investment casting flasks. Waxes are placed in the body of the flask and filled with plaster. In the process of subsequent heating, the moisture from the plaster evaporates and the burnt-out model is removed. Then molten metal is poured into the formed cavity.

To obtain accurate digital models of complex objects, which can later be used in casting, 3d design or 3d scanning is used.

In order for the printer to print, you need to load a 3D model into a special program on a computer that controls a 3D printer. A 3D model is a sample of what we want to print on a 3D printer, created in a special program, for example, AutoCad in the "stl" format.

3D scanning is also used to obtain digital models in various branches of technology and the national economy: cultural heritage objects, products in medical prosthetics, digital archiving, and so on can be digitized.

A 3D printer perceives information encoded in a special format called G-code. This program prescribes the actions that the 3D printer should do when it should do them, for example, the speed of the extruder, the temperature of the extruder, and other parameters.

To facilitate printer management, slicer programs have been created (from the English to slice - to cut). These programs divide the loaded model into layers and describe the procedure for creating each layer in the G-Code language. The most popular slicer programs are Cura and Repetier.

MAIN PART

1. EXPERIMENTAL

To obtain metal castings in the manufacture of prototypes, an improvement in casting technology is possible by eliminating the operation of manufacturing a silicone mold for waxes or the waxes themselves.

If a digital model is developed in the "stl" format (or the master model is subjected to laser scanning) and using 3D printing from a polylactide (PLA) polymer that burns almost without ash, a burn-out model is made, then this model can be used for pouring into a plaster mold.

At the same time, there is no need to change something in the metal casting technology itself, you can use standard, already existing casting equipment.

To test the feasibility of this option, I conducted an oven annealing of model wax and PLA material at a temperature of 700C. Subsequent weighing showed that the weight of the ash residue of both materials is below the sensitivity of the balance (0.01 g).

1.1. 3D DESIGN, 3D SCAN AND 3D PRINT

The models were created in the AutoCad program in the “.stl” format.

In my experiments, I decided to limit myself to simple models. I decided to print the medallion and the cuboctahedron. For an experimental evaluation of the possibilities of laser scanning, I made a model of a cuboctahedron, shown in APPENDIX 2

.

The model for the medallion was created in the AutoCad program, the model for the cuboctahedron was also obtained by 3D scanning.

First, I created an electronic 3D model of the medallion in AutoCad and saved it in the “.stl” format (APPENDIX 3)

For laser scanning, a 3D scanner DAVID starter-kit2 was used (APPENDIX 4).

Consider the scanning process. The scanning scheme and the programming environment are given in APPENDIX 5. When working with the scanner, we first perform calibration. To do this, we fix the camera motionless relative to the calibration panel so that it is at the level of the calibration grid.

The object is placed in the corner of the calibration panel. We turn on the laser and direct the beam into the corner between the calibration sheets. A broken line appears on the monitor, which indicates that the program is ready to work and analyzes the image coming from the camera.

We move the laser beam up and down, form a scan of the given position of the object and save the scan result to a file. To create a model, you need to make several scans, since the scans must necessarily overlap each other so that it is easier for the program to analyze them.

Using the special software of the DAVID scanner, a spatial mathematical model of the object's surfaces is constructed - a 3D model of the object from scans of individual positions by joining the scans and their subsequent merging.

At the next stage, a reduced copy was obtained using a 3D printer - a burnt-out model made of PLA material. At the same time, it is possible to print the required number of models.

In this work, I used the Cura program to create the G-Code, and Repetier to program the 3D printer.

For printing, I used a Velleman K-8200 3D printer assembled by me from a special designer. (APPENDIX 6) This printer uses the layer-by-layer extrusion method in its work. When printing with this method, the raw material (plastic rod) enters the extruder, where it is melted, and then squeezed out of the extruder and superimposed on the part layer by layer. When printing with this method, you need to consider some nuances:

1. When starting the printer, it is necessary to draw several lines not related to the model to remove the plastic remaining in the extruder and warm up the extruder.

2. For better bonding of the lower layers of the part with the surface, it is necessary to heat the printing table. The temperature should provide softening of the plastic, but at the same time not bring it to a temperature at which the material passes into a liquid state.

Also, it is necessary to select the optimal line thickness, because. if the line thickness is too large, the quality of the part decreases, due to the fact that the layers begin to spread and stick together poorly, because they do not have time to cool down, and when the next layer is applied, the previous layer is smeared with the “nose” of the extruder, and if the line thickness is too small, the layers do not stick together as they completely harden before the next layer is applied, and this is why the line spreads again.

1.2. PREPARATION OF THE MOLD AND CASTING

First, I assembled the model with the waxing of the casting cup by wax soldering and placed it in the flask body, in which they were filled (molded) with a special SatinCast 20 plaster mass. pressure tin.

The appearance of the resulting casting is presented in APPENDIX 7.

1.3 CONCLUSIONS ON THE EXPERIMENTAL PART

Thus, as a result of the work carried out, the possibility of improving the casting technology was shown by using a burn-out model from PLA, obtained by digital technologies - laser scanning and 3D printing.

At the same time, there is no need to change the traditional metal casting technology, that is, standard casting equipment can be used.

At the same time, a comparison of the shape, surface quality of the original master model and the one printed on a 3D printer showed that the sharp corners of the model being burned out were smoothed out, the gluing lines turned into small rollers, and the surface acquired a relief. This indicates that the hardware and software used affect the quality of the burnt model. In cases where it is required to transfer small parts, it is necessary to use equipment and software with the appropriate characteristics.

Comparison of the shape, surface quality of the burnt model and the cast part showed that the casting repeats all the features of the surface of the part poured with gypsum in the flask. This indicates that the equipment and materials used for the preparation of the flask and casting provide a high-quality transfer of the shape and quality of the surface of the burnt model.

CONCLUSION

As a result of the work done, I was able to:

1. To study modern production technologies from the point of view of digital production.

2. To study the traditional technology of investment casting (burned out) models.
