Note: You should already have a Magnetic Base or bed clips installed on your printer as this is needed to use a Flexi Plate.

+PEX Prep

Make sure to rough up the PEX surface with 000 steel wool or red Composite Abrasive Pad (CAP is version 7447). On the first preparation, you will need to scuff in circles for 4-5 minutes until you have an even satin matte finish without seeing individual scratches with very little reflection. Clean repetitively with isopropyl alcohol >90% and a fresh/clean paper towel. Do not use other rags, microfiber, wipes, or towels, please see here.

+Level After Install

If your machine has automatic bed leveling, run the leveling process and set your gap such that the first layer is well squished. For more details on achieving the right first layer squish, refer to this bed leveling guide.

If your printer uses manual leveling, follow the same guide for instructions on the leveling process.

+Filament Settings

Always read your filament spool label
Your hot end temperatures should be set within the range printed on the side of the spool of filament. The first 3 layers should be toward the lower temperature range to avoid damaging the PEX. For example, if the hot-end range is 200-230° C, start with 215°C or lower and adjust as needed for your first layer. For bed temperatures, stick with the Wham Bam recommended temperatures as shown in the chart below.

When trying a new filament
We always suggest that when changing filament types and brands or adjusting settings, always print a small test cube (or our Mini Whammy) in the far corner of your build surface. If you do not get good adhesion, you may need to adjust your settings or use glue stick to promote adhesion. If it sticks for the full print and comes off easily once cooled, you are probably good to go when printing larger parts. If it bonds too well, adjust your settings, or use glue stick. When in doubt, use glue stick as a barrier layer. PETG and some other filaments, such as ASA, stick too well and typically need a barrier layer.

+PEX Best Practices

After every print:
Always wait until the printed part and build plate are completely cool before flexing off and never flex when either is still warm. Never force off a print; always flex carefully once cool to remove the part.

After removing the parts always prepare the PEX for the next print by using either 000 steel wool, CAP pads, or a red Scotchbrite 7447 pad. Scuff for about 10 seconds, then clean with 90% or higher IPA and fresh paper. This will help to remove any traces of filament and prevent contaminant build up. Do not use rags, microfiber, wipes, or towels, please see here.

Shipping policy

Last updated: October 27, 2026

Where we ship and shipping charges

Shipping availability depends on the product, supplier, and delivery address. Enter your address at checkout to see the available shipping options and final shipping charge before payment. If no shipping option is offered for your address, we cannot ship that combination of items to that destination. A shipping zone does not mean every product is available in every location.

Fulfillment through our partners

Apex Technica works with fulfillment partners, including suppliers through Shopify Collective, who ship products directly to customers. An order containing products from different suppliers may ship in separate packages. Shipping charges may be combined across packages; review the total at checkout.

Processing and delivery estimates

Order handling generally takes 3–5 business days before dispatch, but varies by supplier and product. Business days are Monday through Friday, excluding holidays. Carrier transit time is additional to handling time. Contact hello@apextechnica.com before ordering if you need an item-specific dispatch estimate or delivery by a particular date. For Collective products, available shipping rates and carrier transit estimates are calculated at checkout. Carrier transit estimates describe time in transit after dispatch, not a guaranteed order-to-delivery date. Weekends, holidays, carrier disruptions, and customs processing can affect delivery.

Tracking and separate shipments

We send shipping confirmation and tracking details when they become available from the fulfillment partner. Separate shipments may have different tracking numbers and arrive on different days. Tracking can take time to show the carrier's first scan.

Address changes, delays, and delivery problems

Check your address before placing an order. Contact Apex Technica promptly to request a correction or cancellation; changes may be unavailable once processing begins. If a shipment is delayed, missing, damaged, or incorrect, contact us with your order number so we can investigate with the supplier or carrier. Do not send an item back without return instructions. See our return and refund policy.

Refund policy

Last updated: October 27, 2026

30-day returns — exception for Collective supplier fulfillment

Apex Technica accepts return requests for products fulfilled by Apex Technica within 30 calendar days after delivery. This standard 30-day return window does not apply to products fulfilled by our Shopify Collective suppliers. Collective-fulfilled products are subject to the applicable supplier's return eligibility, return window, condition requirements, and fees, which may differ from our standard policy.

Products fulfilled by Collective suppliers

Review any supplier-specific return terms shown on the product page before purchasing. If those terms are not shown, contact hello@apextechnica.com before placing your order to confirm the applicable return window, eligibility, shipping costs, and any restocking fee. The exception does not mean that every Collective product is non-returnable. Apex Technica remains your contact for return requests and will coordinate with the supplier. Do not send products directly to a supplier without our return instructions.

Condition for standard Apex returns

For products covered by our standard 30-day policy, items must be unused, in their original packaging, and include all accessories and proof of purchase. This condition requirement does not prevent you from reporting a damaged, defective, or incorrect product.

How to request a return

Email hello@apextechnica.com with your order number, the item you want to return, and the reason for the request. Include photos if the item arrived damaged, defective, or incorrect. We will review the request and provide authorization, the correct return address, and shipping instructions. Returns are made by mail; items from different suppliers may require separate return shipments. Please retain tracking and proof of shipment.

Return costs

For standard Apex returns due to a change of mind, the customer pays return shipping and original shipping charges are not refundable. We do not charge a restocking fee for eligible standard Apex returns. For damaged, defective, or incorrect items, contact us so we can arrange the appropriate return or other resolution without charging you return shipping. For Collective-fulfilled change-of-mind returns, supplier-specific shipping and restocking terms apply.

Refunds and exchanges

After the authorized return is received and inspected, we will notify you of the outcome. Approved refunds are issued to the original payment method within 10 business days after receipt and inspection. Your bank or payment provider may require additional time to post the credit. Any applicable, previously disclosed return charges will be explained. For exchanges, contact us to arrange a return and a separate new order; replacement availability is not guaranteed.

Damaged, defective, incorrect, or missing items

Contact Apex Technica promptly if your order arrives damaged or incorrect, has a defect, or does not arrive. We will investigate with the supplier or carrier and explain the available resolution. Manufacturer warranty coverage is separate from this return policy. Nothing in this policy or a supplier exception limits rights that cannot be excluded under applicable law.
