General Notes on Building Your Own 3D Printer

On a general note, when building a 3d printer first, decide on the type of printer you want to build. Write down the specs of the printer. Make a checklist of all you need. Then, get started.

It is important to note that you can not cut corners when trying to build your own 3d printer. There is no easy way out. Since we assume that you are a 3d printing hobbyist or enthusiast, we trust that you are equal to the task.

You have to make this decision as it will determine the parts that you will buy. Both types of printer differ in some ways which implies that their components will differ.

Your checklist should include the printing speed; size of the printer’s 3d printed object; compatibility of the printing material or filament; the printing resolution; and options for connectivity.

The spec of the printer will determine the outlook of your printer and the cost of buying the parts.

If you do not have several years of experience in 3d printing, you have to keep away from extruders with dual setup. Such setups are very complicated when building and quite expensive. As time goes on, you can upgrade your printer to include another extruder.

Your 3d printer may not look appealing at first sight. It will be raw with so many wires dangling from point to point. Well, you should not fix your gaze on aesthetics. This is the point where you have to put in your best to ensure that you come up with a machine that is functioning.

As soon as your printer is ready to work, you can start thinking about the casing or frame. You can even decide to add features that are fancy. Your printer can be automated by adding a touch screen user interface and WiFi connection.

Furthermore, when thinking about getting the right frame for your printer, do not choose an acrylic frame. It is very fragile and does not support printing in temperatures that are high.

Plastic can be used when choosing some other components. However, you can not choose plastic for the main bodywork.

When you are building your own 3d printer, you need a checklist. It will help you to stay focused and organized. If you have one, you will know the step where you are in the building phase and the next step to take.

Most importantly, you need a lot of patience when building your own 3d printer.

Buying the required components may take up to some weeks. Also, do not forget the time that you will put into designing the outlook of the printer.

If you cannot go through the pain of getting these done, you are better off with the 3d printer kit.
