Wash-1 Process Overview and Basic Operation - Markforged Metal X 3D Printer Getting Started
Let’s discuss the Wash-1 process overview and basic operation for the Markforged Metal X 3D Platform. In this post and video, we will delve into the importance of the wash step in the 3D printing workflow and guide you through the entire process.
Why Do I Need to Wash?
The wash step is a vital part of the Markforged Metal X 3D printing system. Before we explain the operation, let’s understand why it is necessary. The filament used in this printer contains a special wax that facilitates the printing process. However, this wax is not suitable for the sintering process. Therefore, it is crucial to remove as much wax as possible using the wash step. The empty space where the wax is removed allows for outgassing of the remaining binder.
Safety Precautions
Before we get into the technical details, it’s essential to prioritize safety. Working with the solvent involved in the wash step requires caution. We recommend wearing gloves, a mask, and eye protection to minimize any potential risks. Careful not to put hands below the coils and don’t keep your head directly above the open chamber. Safety should always be the top priority!
Operating the Wash-1
Now, let’s go through the step-by-step process of operating the wash station for the Markforged Metal X 3D Printer.
1. Weighing the Parts:
Once you remove the printed part from the printer, it is crucial to keep track of its weight. Using a precise 0.01 gram scale, individually weigh each part. You can carve the weight into the bottom of the raft or find an alternative method to note it down. This step is essential to ensure the proper removal of wax during the wash process.
2. Preparing the Wash Station:
To begin the wash process, open the left-hand side of the wash station. However, be cautious not to put your hands below the condensing coils, as there might be evaporated solvent in the air, which can come in contact with your skin. After opening the wash station, lift the basket and let it rest using the slots on the lid. This resting time allows the solvent to drip down and be reclaimed into the system.
3. Placing the Parts in the Wash Station:
Now, it’s time to place the parts in the wash station. If you have a specific part that has a cup-like feature, ensure that it is placed facing downwards. This orientation prevents the part from being filled with solvent, simplifying the process of removing it later. Remember to handle the parts carefully to avoid any damage.
4. Initiating the Wash Cycle:
Once you are satisfied with the placement of the parts in the wash station and have recorded their weights, gently slide the basket back into the wash station. Close the wash station and mark the part as “washing” in the system. The system will notify you about the required wash time based on the geometry. Additionally, an email notification may be sent once the part is ready to proceed to the drying phase.
5. Drying the Parts:
After the specified wash time, lift the basket and let it drip for a couple of minutes. Then, transfer the parts from the basket to the right-hand side of the wash station, where they will undergo drying. The ventilation system will evaporate any remaining solvent inside the parts, making them ready for the subsequent steps. Remember to mark the parts as “drying” in the system.
6. Verifying Weight Loss:
Upon completion of the drying process, weigh the parts again. Enter the before and after weights into the system. The system will analyze the weight loss and notify you if the parts have lost enough weight or require further washing. It’s important to note that overwashing is not detrimental, so don’t worry about them staying in the wash station for an extended period if necessary.
Conclusion
The wash step plays a critical role in preparing 3D-printed parts from the Markforged Metal X 3D Printer for the subsequent sintering process. By following the outlined steps and prioritizing safety, you can achieve optimal results. Remember, patience is key, and adequate wax removal ensures the production of high-quality parts. Now that you are familiar with the wash process, you can confidently integrate it into your 3D printing workflow.
