If you can’t afford the genuine items, make sure the cheaper alternatives you’re considering have a solid reputation. In this section, we’ll list down the parts you need to build a 3D printer, from the electronics to the extruder to the print bed. When shopping, be wary of cheap knock-offs of popular products, as they often have serious quality issues and don’t tend to last very long. The parts you need to obtain depend on the mechanical arrangement you want for your DIY 3D printer, so make sure you decide on one before you go shopping. Fused Filament Modeling is the most popular process and it will be this type of 3D printer that we'll look at in this tutorial.
Choosing the right software for your 3D printer is another important thing to keep in mind. Most 3D printer kits will come with a default program for you to use. But most users will want to add on additional firmware or software.
What are The Steps to Make Your Own 3D Printer?
Decide on whether you want to go bowden or direct extrusion. With Bowden extrusion the stepper motor and extruder are stationairy and push filament through a bowden tube to the hot-end. The advantage of this is a light weight hot-end where forces of mass play less of a role moving the hot-end around. With direct extrusion your stepper motor and extruder sit on top of the hot-end. Keep in mind that although not impossible, it is harder to print flexible filaments with bowden.
Most steppers are 1.8 degree steps but going with 0.9 Degree can get you more accuracy but you'll sacrifice on speed . The videos and tutorials available online are very helpful in assisting individuals to carry the project with successful results without any prior knowledge of the field. A closed design is very helpful in increasing the potential of your 3D printing. Before you plan to order temperature sensors, remember to check the quality and get it from a renowned brand. These could, otherwise, become a huge problem later when printing. Although you can get the best quality linear guides available in the market, these won’t be capable of holding the quality for long.
Helpful Software
Although you must keep the complexities away and stick to the basic design, this is something that must be included. Also, the temperature sensor must provide a decent thermal coupling to the hot-end heater block. This could transform your device into a standalone machine, capable of working without any connection to the external source. Hence, you must ensure that the components forming the drive system are well configured. If you need any assistance, you can again reach out to the experts online.
Acrylic is cheap and can be easily manipulated but is prone to cracking as well as wobbling due to the lightweight nature of the material. Wood is also easy to manipulate but is similarly not ideal for high-temperature and high-speed performance. The cost of a 3D printer depends on the technical specifications and functionality. Inexpensive products have a standard set of options and are more suitable for beginners who want to try their hand at 3D modeling.
Thought out Belt and Spindle Drive Systems
This method could be less expensive if compared to a fully assembled 3D printer or a 3D printer kit. Firmware is the software that runs on a 3D printer’s microcontroller. It works to translate the contents of the G-code into electric signals. These signals work to either activate or deactivate the printer’s components.
Materials however come in a variety of differences and each has it's printer requirement to operate at optimum. If you are on a tight budget, you may feel like using a 1.8° step-angle stepper motor. You must be planning to take work from your 3D printer and not store it at a corner as an accomplishment.
PLA is the easiest and requires the least functionality from your printer. Heads up, the Cartesian is a bit easier to configure and maintain than the Delta Kossel. They say, a Delta Kossel 3D Printer has the advantage that it can print faster but some say the other type of printer have long since caught up. Also if you're looking for speed you may have picked the wrong hobby. I built designed my first printer 4 years ago without an ounce of experience in robotics and electronics. You cannot just decide a day to make your own 3D printer and start putting different parts together.
Once you have decided on all the specifications for your 3D printer, you will need to gather all the parts needed. The basic parts you will need include the Controller, Stepper Motors, Print Head, End Stops, Print Bed, Power Supply, and Printer Frame. We will discuss more details about the specifications and the parts needed below. Of parts and its dimension, you can change the dimension as per your convenience.
The most common printers are either a Cartesian 3D printer or a Delta Kossel 3D printer. An example of the common Cartesian 3D Printer is something like the Prusa I3 and a well known example of a Delta Printer is the AnyCubic Kossel. The learning experience that the DIY projects add is very useful in understanding the nitty and gritty of the 3D printing niche. This has a non-graphical display, however, it can cater to most of the configurations required to start the printing process. Want to make your 3D printer a standalone device, needing no help from external devices? If that is so, plan to include the LCD controller with an SD-card reader.
According to the method of three-dimensional "printing", 3D printers are distinguished by cold and hot action. In the first case, photopolymers are used as the initial “raw materials”, and in the second, a special plastic thread of different colors is used. To build a 3D printer from scratch, you will need to collect several materials and be prepared for a time-consuming task.
