- Using an SD card or internal memory can offer advantages in transmission speed and stability
How to Connect Your 3D Printer to Your Computer or Laptop
So if you’ve decided to link your computer to your PC there are different ways you can go about that. The sort of connection you can use depends on the sort of port configuration that comes with your printer.
Most printers come with an SD port and a standard USB A port. Recently, newer model 3D printers have started using wireless connections like conventional printers. With some further configurations and settings, even older models without Wi-Fi capabilities can now enjoy wireless capabilities.
USB, Wi-Fi, and USB proxies like OctoPrint are the preferred methods for connecting to PCs. Let’s take you through how these work.
USB Connection From Your 3D Printer to Computer
This is still the most popular method. USB remains the default configuration on most printers, so this is the logical choice for most users. Although variations can exist between different brands, the connection process largely remains the same.
What Do You Need to Connect Your 3D Printer to a Computer?
- Your 3D printer
- Your computer
- A USB cable that has the right connection to the 3D printer (usually a Type A)
- The relevant software, drivers, and firmware updates if needed
Let’s take you through how you can use a USB to connect your printer to your PC.
Step 1: Check the ports
- Before connecting the cables, it’s best to check if the ports on both devices, especially the PC, are functioning properly. You can use a tool like a mouse to check it.
Step 2: Connect the devices
- You can do this with standard USB Type-A wire that come in the box with the printer.
- It’s best to use short thick cords. These cords provide the highest data quality.
- Great data quality is needed to prevent interruptions during printing.
Step 3: Install device drivers.
- USB devices nowadays are mostly plug and play. Just plug in the device and watch the drivers install automatically.
- In some cases, the drivers might come in a disk or a drive, and you might need to install it manually.
Step 4: Install the printer control software.
- After installing the required drivers, you might need to install the printer’s software that comes with it.
- The printer’s software can come with the printer, or you might need to download it from the manufacturer’s website. Repetier-Host and Pronterface are good software that many people use.
- Open the device software and follow the manufacturer’s settings for proper configuration.
And just like that, your printer is ready to use.
The video below is a great tutorial using the Pronterface software.
When going through all these steps and installing the necessary software, sometimes there may be unexpected glitches. We have compiled some of the frequently encountered glitches and their solutions.
Wi-Fi Connection From Your 3D Printer to Computer
To set up 3D printing via Wi-Fi, you need:
- A wireless-capable 3D printer
- A home wireless network/ router
- A wireless-capable PC
With a Wi-Fi capable 3D printer, you should have specific instructions to take you through the process to connect things up. With my Anycubic Photon Mono X, the Wi-Fi setup was fairly basic to follow, though it has limited functionality.
Other 3D printers with Wi-Fi functionality usually have many benefits and control so I’d definitely look out for those.
(Note: On some printers without a LED display, you need to connect the printer to the PC via USB initially to be able to connect to the Wi-Fi network.)
Step 1: Power up the printer, router, and PC
Step 2: Install the printer, software, or firmware on the PC
Step 3: Connect the PC and the 3D printer to the router
Step 4: Click on the connected device on the PC and select the printer from the list.
Step 5: Open the printer software and configure the printer
Step 6: Send your models to the printer for printing
You can choose to use something like the Creality Wi-Fi Box to start a Wi-Fi connection to your 3D printer. The video below by Teaching Tech is a walkthrough and review of this product.
Connecting Your 3D Printer Wirelessly With OctoPrint
Octoprint is a great way to connect your 3D printer to your computer. It began as a way to print remotely for 3D printers without wi-fi capabilities.
