Shipping & Returns

COVID-19 Update: We are still shipping most in-stock items within 24 hours during weekdays. Our UPS and USPS pick-ups are usually early in the morning, so we cannot guarantee that items will ship out the same day. 

All shipping carriers (UPS, USPS, DHL, etc) are experiencing delays, so please expect an additional 1-7 business days beyond the estimated delivery date, and possibly longer, depending on your location. Both UPS and USPS have suspended their service guarantees. 


$4.99 flat rate shipping is limited to our continental U.S. customers only. Flat rate shipping method will be either USPS, UPS or FedEx, whatever is most cost efficient. If you need a specific carrier, do not choose flat rate shipping, instead choose your preferred carrier at checkout. 

Standard flat rate shipping time is 3-7 business days, but could be longer depending on the destination.

When choosing a shipping method, please note that delivery times listed are estimates provided by the carrier (FedEx, DHL, USPS, UPS) and do not include weekends, holidays or our handling time. However, most in-stock items will ship within 24 hours (excluding weekends and holidays). 

Undeliverable/Returned Shipments

If an order is returned to us as undeliverable, unclaimed, refused or for any other reason, we will issue store credit for the order. Original shipping charges and any return shipping fees we incur will be deducted from any store credit.


An order can be canceled anytime before it is shipped. Once an order ships, it cannot be canceled and will instead need to be returned according to our return policy below.

Our goal is to process all orders in less than 24 hours. Most orders placed before 11am weekdays will ship the same day, so if you would like to change or cancel your order, please contact us as soon as possible and we will do our best to accommodate.


We hope that you love everything you order from us, but we understand that when shopping online, occasionally returning an item is unavoidable. Other than the exceptions listed below, all unopened and unused items may be returned within 30 days of purchase.

To start a return, log into your account, find the item in your order history and chose the return option. After you submit your return request, we will then be in touch via email with return instructions and your RMA#. Items received without an RMA# will not be refunded and will not be returned to the sender.

The following items are not returnable for any reason:

  • Used items - any item that has been installed on a printer or used in any way
  • Open items - any item that has been opened or had a seal broken on the packaging - This includes filament 
  • Electronic items (this is any item that has a circuit or contains a component with a circuit)
  • Clearance Items

  • Special order/bulk order items

Important Notes:

Returns must be received within 30 days of your original order date. Items received after 30 days will not be processed.

Items received without an RMA# will not be refunded and will not be returned to the sender. You will receive an RMA# from us after submitting a return request from the order history page of your account

Returned items must have all original (undamaged) packaging, be unused and returned in resellable condition.

Shipping costs are nonrefundable. 

Buyer is responsible for return shipping.

If you like, you can use our return shipping label and we will deduct $7.99 shipping from your refund. If using our return shipping label, we will automatically add insurance.

If you chose not to use our shipping label, we highly recommend shipping insurance and tracking when returning an item, especially for higher dollar items, such as 3D printers. Partsbuilt 3D is not responsible for returned items lost or damaged in shipping.

Opened, damaged, used, items with missing parts and packaging or otherwise not fit to resell will be rejected and disposed of unless the buyer wants the item back, in this case the buyer will be responsible for the cost of shipping the item back to them.

Items Damaged During Shipping 

If an item is damaged during shipping you must contact us within 3 days of tracking showing the item as delivered. Please email photos of the damaged shipping box and contents to 

Defective Products

Due to the technical nature of 3D printing, it is our policy to first troubleshoot any items that are thought to be defective, as we have found that usually other variables are causing the issue (settings, poor quality/damp filament, etc.) and most of the time we are able to resolve it through troubleshooting.
If, after troubleshooting, the item still isn't working, we will send you an RMA# to return the item to us and we will send you a replacement at no charge.
If an item is suspected to be defective, we ask you contact us right away, as after 30 days from your order date, you will have to go through the manufacturer to make a warranty claim.


Refunds are processed and refunded to the original form of payment or as a store credit (generally within 48 hours of us receiving your return). It can take up to 10 days for the credit to show up on your account.

Consignment and Special Order Items

Consignment items are sold as-is and are not returnable/non-refundable.

Special order items are not returnable/non-refundable.

Bulk orders of an item we normally stock is considered a special order item and therefore cannot be returned.
