Ordering and files
- What file types do you accept?
- STL, 3MF and OBJ, up to 100 MB each. You can add several files to one order. Each model gets its own material, colour, settings and quantity.
- Do I need to create an account?
- No. You can order as a guest and check your order status with the link in your email. If you later sign in with the same email address (with Google or a code sent by email), your earlier orders will show up in your account.
- What's the largest model you can print?
- Up to 256 × 256 × 260 mm in one piece, or up to 235.5 × 256 × 256 mm when printing with two nozzles. Split a larger model into parts in your file and glue them together after printing.
- What if my file has errors?
- We check every file before printing. We don't change your design ourselves. If the model can't be printed with the settings you chose, we'll write to you before we start. You can fix the file, change the settings or cancel – in that case we'll refund your full payment.
- What won't you print?
- Weapons and weapon parts, including firearm parts, silencers and magazines. Items that infringe copyright, registered designs or trademarks. Illegal or offensive content. We'll reject such orders and refund your money.
- What do you do with my files?
- We only use them to prepare your quote, make your order and handle a complaint if there is one. We don't share or publish them. Files you don't order are deleted 24 hours after your last quote, or straight away when you remove them from the quote. Files from orders are deleted 90 days after delivery.
Prices
- How do you work out the price?
- The price is calculated automatically by software (a slicer) from your file: the amount of material, the print time and the settings you choose, such as material, layer height and infill. You see it as soon as you upload the file.
- Can the price change after I order?
- No. The price in your order summary is binding. You don't pay extra, even if the print uses more material or takes longer.
- Is there a minimum order value?
- Yes, PLN 39.00 for products. If your order is below that, we add a top-up to reach this amount. You'll see it in the summary before you place your order.
- Is it cheaper if I order more pieces?
- Yes. The price per piece of the same model drops by 5% from 10 pieces, by 8% from 25 pieces, by 12% from 50 pieces and by 15% from 100 pieces. The discount is already included in the quote. You can enter a discount code in the cart – one per order. Discounts can't be combined: out of the quantity discount, a code and the stamp card, we apply the one that makes your order cheaper.
- Do regular customers get a discount?
- Yes – with our stamp card: every 5th order is 10% off. When you order while signed in, each paid order adds a stamp to the card in your account, and the discount is applied automatically.
- Do you issue invoices?
- We don't issue VAT invoices because we're exempt from VAT. Our prices are final and we don't add VAT to them. If you ask, we'll issue a bill (rachunek) – tick this option in your order or write to us within 3 months of receiving your print.
Materials and quality
- What materials do you print with?
- PLA, PLA Matte, PETG, ABS, ASA, TPU 95A, PETG-CF and PA6-CF. You choose the colour of each material in the quote.
- Which material should I choose?
- PLA: prototypes, mock-ups and models. PLA Matte: display pieces, gadgets. PETG: functional parts, holders and mounts. ABS: electronics enclosures, car parts (interior). ASA: outdoor parts, car and bike parts. TPU 95A: seals, bumpers and buffers. PETG-CF: drones and RC models, jigs and templates. PA6-CF: gears, brackets and machine parts. Not sure which one to choose? Try our material advisor – answer a few questions and we'll suggest a filament.
- How accurate are the prints?
- You choose a layer height from 0.06 to 0.36 mm – the lower it is, the smoother the surface and the longer the print. Dimensions can differ from the file, usually by up to ±0.2 mm. We remove supports before shipping, but small marks may remain where they touched the model. Layer lines are a feature of 3D printing, not a defect.
- Are prints safe for contact with food?
- We can't guarantee that. There are tiny gaps between the layers of a print where bacteria collect, and our process isn't certified for food contact. Don't use prints for medical purposes or anywhere people's safety depends on the part. You'll find the heat resistance of each material on our Product safety page (in Polish).
Delivery and payment
- How long does it take?
- We ship your parcel within 2–4 working days after your payment is received, or within 24–48 h with express service (+50% on the product price). Delivery usually takes 1–2 days after dispatch. We only ship within Poland.
- How much does delivery cost?
- From PLN 16.99 (InPost parcel locker 24/7). For orders of at least PLN 199.00, delivery by InPost parcel locker 24/7 and InPost courier is free. The full price list is on our Delivery and payment page (in Polish).
- How can I pay?
- Online through our payment provider: BLIK, Przelewy24 or a payment card. You can also pay by regular bank transfer – we then start work once your payment arrives.
Complaints and returns
- Can I return a print within 14 days?
- No. Your print is made to your file and settings, so the right to withdraw from the contract doesn't apply (Article 38(1)(3) of the Polish Consumer Rights Act). This doesn't limit your rights if the print is faulty or doesn't match your order.
- Can I cancel my order?
- Yes, free of charge, as long as we haven't started printing. Email us with your order number. We'll refund your full payment within 5 working days.
- What if my print is damaged or doesn't match my order?
- Write to kontakt@dobrawarstwa.pl. Give your order number, describe the problem and attach photos. We'll reply within 14 days. If your complaint is justified, we'll reprint the model at our cost or refund your money.
You'll find the detailed rules in our Terms and conditions and on the Delivery and payment and Complaints pages (in Polish). You can read about materials on the Materials page.
