UPDATE: 2023-07-01
I have great news to share with you! After a thorough analysis, testing, and observation, we have identified effective solutions for the heat dissipation and buckle loosening issues with the Dual Extrusion Module. We’d like to update you on our latest plan.
We are currently preparing a replacement kit specifically targeting the reported issues. While the occurrence of each problem may vary, we aim to provide a convenient solution for the users who require it. The replacement kit consists of four different components, each addressing a specific issue:
- Silicone Buckle Wedge for the Dual Extrusion Module - Fixing the popping feeder levers.
- Front Cover for the Dual Extrusion Module - Optimizing cooling airflow with the improved design.
- Spare part for the Dual Extrusion Module filament sensor - Reducing wear on the trigger lever to prevent false alarms.
- Silicone Bed Shims (0.5 mm thick) for the Artisan 3D Printing Platform - Resolving incomplete contact in some machines during the leveling process.
Considering the traditional support service process where users have to contact our Support team for troubleshooting and arranging the delivery of replacement parts, it usually takes about a week. This time, we want to improve the efficiency of users obtaining replacement parts and resolving their issues. Therefore, we plan to make the replacement pack available for self-ordering on our official online store.
To show our appreciation, we will be providing all existing customers with a one-time free coupon for the replacement kit. When using this coupon, our loyal customers can enjoy a zero-cost purchase, waiving the additional logistics fee. However, due to the high logistics cost of international express shipping from Shenzhen, China, we plan to prepare the replacement kit in bulk and ship it to our overseas warehouse via sea freight. Once the pack arrives at the warehouse, it will be made available on our official online store. At that time, we will send out the replacement pack coupons and provide more information through official emails to our existing customers.
Please note that the replacement pack is only necessary if you encounter the specific issues we mentioned above. Otherwise, if the machine is functioning normally, we do not recommend users to replace any parts.
Regarding the timeframe, we are in the process of preparing the materials for the replacement kit and plan to ship it by sea freight in mid-July. As an example, for customers in the United States, we estimate that the replacement pack will arrive at the overseas warehouse by mid-August and be delivered to users in late August. The sea freight time to Europe is expected to be around two weeks longer than to the United States. However, customers in China will receive the replacement pack earlier, as their logistics time only takes one to two days. We will closely monitor user feedback regarding the replacement parts and promptly share updates in the community.
Once again, we appreciate your understanding and support! If you have any questions, please feel free to leave a comment on this topic.
Make Something Wonderful.

Hey Artisans!
We’ve heard your concerns about the extruder buckle problem during 3D printing, and we understand how frustrating it can be. While we work on a long-term solution, we wanted to offer a temporary fix to get you back on track.
Here is the buckle wedge model STL file! This little solution can help stabilize the extruder buckle and prevent filament extrusion issues.
Here’s what you need to do:
IF both extruders are experiencing this problem and are unable to print, insert a plastic block (3 mm thick) between the buckle as illustrated, making it able to print first.
Download the buckle wedge model file here and print it out with PLA or TPU.

IF you’ve inserted a block in Step 1, remove it now.
Carefully insert the wedge between the buckle as illustrated to increase the clamping force and prevent the buckle from breaking loose.
We understand that a long-term solution is what you all need, and we want to assure you that the silicone pads with adhesive backing are currently being prepared. Your feedback and patience are incredibly important to us during this process. We kindly ask for your understanding and to wait patiently for the upcoming permanent solution. We’re committed to providing you with the best experience possible.
Stay tuned for updates in the community, and as always, keep sharing your feedback and engaging with the community.
