Motor Resonance Rippling (commonly known as VFA) is a major factor in print surface quality loss. We designed specialized and optimized motors for the X and Y axis that can greatly reduce vibration which causes the MRR and hence solve the problem from the source, boosting the surface quality.
Each X and Y motor we produce is tested with reports attached and only those with more than 75% vibration reduction relative to the original ones are qualified. By doing so we make sure that every motor we delivered will reduce MRR from the source and improve the print quality.
Compared to the original motors, the Prorifi3D motors offer higher performance by reducing resistance and inductance while maintaining the same holding torque. Through testing and optimisation, by increasing the motor's operating current appropriately*, our motors achieve up to 2x the maximum speed and 5x the maximum acceleration** with only a 20% increase in heat generation. The heat sink included in the kit even keeps the motors running cooler than the stock condition, ensuring stability.
* The motor running current of the i3 series can be adjusted directly by G-code, or by modifying the firmware
** Original: default 200mm/s@1000mm/s^2; 360mm/s@5000mm/s^2 after Stage1 upgrade; 400mm/s@5000mm/s^2 after Stage2 upgrade
i3 series maximum speed and acceleration limit breakthrough requires firmware modification
*Our motors are developed specialized for the original Mk3 series. After complete compatibility tests, the motors are perfectly compatible with MK3/MK3S/MK3S+, and no compatibility issues have been found so far for our motors on MK2.5. In addition, our motor kit is also fully compatible with the Bear upgrade frame.
The rigidity of the printer system is mainly determined by the timing belt and the frame. Therefore, based on Stage1, we further optimized the printer frame structure and further enhance it with the effectively wider timing belts. These makes the new design approximately 15 times more rigid in the Y-axis than the original one.
At the same time, we designed an innovative dual belt system that shifts the two belts by half-pitch to compensate for the polygon effect caused by the wider belts. These improvements, combined with our stage1 motor upgrade kit will make your machine almost eliminate MRR and further reduce other imperfections such as Ringing, achieving an almost perfect surface print quality.
* To apply the Prorifi3D frame upgrade you only need to print the plastic parts yourself. Pick your favorite color and build a unique machine!

As an Open-source project, our solutions and kits are developed based on the findings from the community. We cannot go this far without all the active members of the 3D Printer Community around the globe, who shared their wisdom and experiences with us.
Our solutions are upgrade kits that are built upon the existing designs. Here is a list of names and projects that we would like to thank and credit for their direct or indirect inspiration to our research and solutions:
Payment & Security
Your payment information is processed securely. We do not store credit card details nor have access to your credit card information.
If you are not happy with our product, or you have changed your mind, you can ask for a return within 7days after delivery.
*note that sealed products or consumables, which are opened, are not eligible for return.
Be aware that money transfers can take up to 14 business days. Please kindly allow the transaction to be processed by the bank or financial institute.
you can ask for a refund when the order is under processing but not shipped yet. In such a case, we will not be able to provide you with a full refund because the product production and package process have already begun. If you insist on asking for a refund, a fee of 15% of the total good price will be charged (shipping fee will get a full refund). To launch the request please send us an email at firstname.lastname@example.org with subjects starting with [Refund request]
Once the refund process is completed. You will receive a full refund via the payment method you originally selected (Credit card, PayPal, etc.).
After receiving the order (Delivered or Shipped order)
In other cases, If the order has already been shipped or you have already received it, you are eligible to return it without a reason within 7 days after the delivery. However in this case, please do not directly reject the package or your goods will not be refundable.
If your order just shipped within a day and you changed your mind, a 35$ interception fee will be charged (deducted) to stop the delivery. In this case, we do not guarantee the interception will be successful.
If your order is shipped more than a day, please kindly wait and start the return process as instructed below.
If your decision is due to quality issues or missing parts, please send us an email at email@example.com subjects starting with [Return request].
All shipped goods have to be returned to us before we can proceed with the refund. In order to prepare the package for return, please follow the steps listed below:
Send a return request: Send an e-mail to firstname.lastname@example.org subjects starting with [Return request], with the subject and description of your case. The e-mail must include the original invoice number of the order you want to return and a short statement for why you want to return it. Your feedback is valuable to us.
Return label: Once we have processed your request, you will receive an email with a shipping label(with all necessary info) and further instructions on how to contact the transporter. Then you may have to contact the transporter later by yourself.
Packing: If you have not thrown the original packing material, that is great. If you do not have the original packing material, do not worry. We will send you an email with guides attached for you to find out what to do in both cases. If you failed to follow the instruction and cause damage during the shipping. Then relevant losses will be deducted from your refund. If possible, take a photo before you return so we can check if the shipping company damaged the package. Discrepancies could influence the refundable amount.
Order returned: Once the goods are received, we will inspect the returned goods and issue the refund later. The returned product(s) will be checked for any missing or damaged parts.
Once the refund process is completed, you will receive a refund via the payment method you originally selected. Shipping costs are non-refundable, the cost of return shipping will also be deducted from your refund.
However, if the issue is created on our side regarding the shipped order such as sending the wrong color, missing parts, etc, all shipping costs will be covered by us. And we will send a replacement as soon as possible.
Before returning the product, please take a picture of the product and provide it to us.
It may take up to 25 days for us to receive the product. then about 2 business days to process the refund, and the refund amount will take 3 to 5 business days to appear in your account.
