Slice Engineering Shipping & Returns Policy

Shipping & Returns


We ship to anywhere in the USA, including all territories, via UPS. Additional shipping charges may apply for deliveries to Alaska, Hawaii, Puerto Rico, US Virgin Islands, or Guam. UPS SurePost is available for free to the contiguous United States for orders over $50 that solely contain products manufactured by Slice Engineering. All shipping rates are auto-updated based on carrier published rates. Our shipping times are estimates and are calculated in standard business days and do not include holidays or weekends.


We now ship to over 30 countries via UPS: Argentina, Australia, Austria, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Iceland, India, Ireland, Israel, Italy, Japan, Latvia, Mexico, Netherlands, New Zealand, Malaysia, Norway, Poland, Portugal, Saudi Arabia, Serbia, Singapore, Slovakia, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey, Ukraine, United Kingdom, and U.S. Outlying Islands. We do not offer discounted shipping for international orders. All shipping rates are auto-updated based on carrier published rates. Customers are responsible for customs and import duties into their country of residence (Incoterms DAP) unless selecting a shipping method that includes the upfront payment of duties and taxes (DDP). DDP check-out methods can be identified by the phrase "Duties & Taxes Included" in the shipping description. Our shipping times are estimates and are calculated in standard business days and do not include holidays or weekends.


The following items may have some lead time: Bondtech LGX Shortcut - Mosquito® Hotend, Bondtech LGX with Shortcut Mosquito Hotend

Orders including these items will be shipped out when they are available. If ordering any products with lead time or products on backorder/preorder, please note that any additional items in your order will be shipped with these products. If you need to order additional items and want them to arrive sooner, please make a separate order for those items.


Despite our best efforts, shipping delays may occur with certain carriers, like USPS or UPS. Although we do offer a range of shipping options (including a free UPS option on certain orders), please keep this potential delay in mind as you choose your shipping option. Our shipping times are estimates and are calculated in standard business days and do not include holidays or weekends. Please see RETURN & REFUNDS for shipping refund information.

Please note that not every shipping method comes with additional tracking and insurance services. UPS® Worldwide Economy DDU service levels are increased to 20+ business days for some countries. This service level is provided by UPS and final delivery will be made by USPS or a local courier in your country of residence. UPS® Worldwide Economy DDU does not include additional tracking and insurance, which can lead to increased wait times. If you have questions regarding shipping to your country, please reach out to Slice before making your order. If you want to include insurance on your order please select another delivery method.

UPS 2nd Day Air® and UPS Next Day Air® services do not include Saturday delivery. Please consider this when placing orders before the weekend and/or after our expected fulfillment hours, such as Thursday or Friday afternoon and evening. Please contact us directly if you want to guarantee when your order will ship. We cannot cancel an order once it has shipped.


As we have a small team, we work hard to get packages out on time. If you order before 11AM EST during the business week, you can expect your package to be shipped out that day. If you place an order after 11AM, your order will likely go out the next day.

Note: We do not ship on the weekends or holidays. If you place an order after 11AM on Friday, your order will likely not get shipped out until the following Monday.  

UPS® Worldwide Economy DDU and DDP are bulk economy shipping methods. Orders with this method are fulfilled on the same timeline as all of our other orders, but their shipping date may be delayed by 2-3 business days due to waiting for enough volume to send them out. When you place an order with one of these methods, you will not get shipping notification until we are able to send your package out. This time is included in our estimated delivery time at checkout.


Discount codes cannot be stacked/combined with other promotions.


We are proud of the things we make. An incredible amount of thought and sweat (and sometimes blood and tears!) goes into every design. All of our products carry a limited lifetime warranty against manufacturing defects. We will repair, replace, or refund any product that does not meet your satisfaction due to a manufacturing defect. Simply contact us with the reason for your dissatisfaction, and ship the product back to us at:

Slice Engineering, LLC
747 SW 2nd Ave, IMB 36, Suite 296
Gainesville, FL 32601
United States 

To complete your return, we require a receipt or proof of purchase. Returns can be initiated here.

Once your return is received and inspected, we will send you an email to notify you that we have received your returned item. We will also notify you of the approval or rejection of your refund. If you are approved, then your refund will be processed, and a credit will automatically be applied to your credit card or original method of payment, within 14 business days. Please Note: Refunds for items returned for reasons other than manufacturing defects and seller packaging mistakes will be subject to a restocking fee and not include the cost of shipping on the original order.  

All refunds due to reasons outside of manufacturing defects must be initiated within 30 days of the original purchase. Returns must meet the below conditions:

1. The product isn’t used or damaged
2. The product must be unopened and in the original packaging
3. You have proof of purchase directly from the Slice Engineering website
4. Return is pre-approved via the return form

Upon receipt of your item, as long as the above conditions are verified, the refund will be issued via the payment method with which your initial order was made minus the restocking fee. Please reach out to us directly before attempting to return any items that do not meet these conditions, as these will be subject to additional consideration at the discretion of Slice Engineering and possibly alternative refund methods, such as store credit or altered restocking fee.

Late or missing refunds (if applicable)
If you haven’t received a refund yet please follow these steps:
1. Check your bank account again
2. Contact your credit card company, it may take some time before your refund is posted.
3. Contact your bank. There is often some processing time before a refund is posted.
If you’ve done all of this and you still have not received your refund yet, please contact us at

Gift cards cannot be returned or refunded. 


USPS First-Class®, USPS Priority Mail®, and Economy shipping services do not come with a money back guarantee if actual delivery is later than estimated.  USPS Priority Mail is an estimated 1-3 business day delivery, but this is based on location and pickup time. See the USPS website for details on this service level. Guaranteed delivery services include UPS 2nd Day Air®, UPS Next Day Air®, and DHL Worldwide. Full refunds will not be issued on delayed orders unless or until confirmed lost by the carrier. Requests to reship lost international parcels may be asked to upgrade the shipping at the customer's cost to ensure safe delivery.


Items returned for reasons other than manufacturing defects and seller packaging mistakes will be subject to a 10% restocking fee or a $5.00 USD flat fee (whichever is lower). The 10% restocking fee will be calculated based on the price paid by the customer at the time of purchase for the goods being returned (excluding tax and shipping costs).  Items approved for return by exception to the above reasons may be subject to a 5% restocking fee instead of the 10%, with no $5 lower option. Restocking fees will be deducted from the refund amount that will be returned to the customer after the return is complete.


For items that are returned due to manufacturing defects and seller packaging mistakes, Slice Engineering LLC. will pay and provide return labels to ship those items from the customer back to Slice Engineering LLC. 

If items are returned for any other reason, the customer is responsible for paying for the shipment of these items back to Slice Engineering LLC.


Returns or refunds for products purchased through resellers must be pursued through the reseller. We cannot process returns or refunds for products not purchased directly from Slice Engineering.
