3D Printing FAQs

No account is needed. You can order an uploaded model or a shop item as a guest. Your guest cart stays in this browser and does not carry over to another device.

We accept .STL, .OBJ, .GLB, .GLTF, .3MF, .STEP and .STP files. Each file can be up to 50 MB. Contact us for larger files.

We measure your model and price it automatically; a shop item is priced the same way, from the model we list. For SLS, the price of a part comes from:

• Estimated weight: We calculate this from your model’s solid volume and the material density, then apply a rate per gram.
• Size: The longest edge of your part decides which size band it falls into, and each band has its own rate per gram. A large, hollow part takes up more of the build chamber than its weight alone suggests.
• Order weight: The heavier the total of the SLS parts in your order, the better the rate per gram, at published thresholds. The discount applies to everything in the order, not just the part that crossed the threshold.

On top of the parts, an order carries a one-off setup charge and a small processing charge for each part after the first. Both are itemised in your cart, and you can open the price breakdown on any quote to see exactly how the total was reached.

We securely accept all major credit and debit cards (Visa, Mastercard, American Express), Apple Pay and Google Pay via Stripe. We do not store your card details on our servers.

Yes. We only use your files to manufacture your specific order. We do not share, sell, or distribute your models, and we do not use them to train machine-learning models. We keep a file only as long as we need it, and you can ask us to delete yours at any time. See our Privacy Policy for more details. The models in our shop are ours or licensed to us: buying a shop item gives you the printed part, not the model file, and the 3D preview on the product page is for display only (see our Terms of Service).

FDM (PLA) prints will have visible layer lines (usually 0.2mm height). This is normal for 3D printing.
Resin prints have almost invisible layer lines and appear smooth to the naked eye.

Currently, our maximum build volume is:
SLS: 165mm x 165mm x 300mm
FDM: 400mm x 400mm x 400mm
Resin (SLA): 335mm x 200mm x 320mm
Models larger than this will need to be scaled down or cut into pieces.

Most orders are printed, cleaned and cured within 1–3 business days; large or complex orders can take up to 7 days. Standard shipping within Australia then takes 5–7 business days, or 1–3 with Express. You will receive a tracking number via email once your order ships. See Shipping & Delivery for rates and international delivery.

Please take a photo of the damaged item and the packaging immediately. Email us at info@inseralabs.com within 7 days of delivery, and we will reprint and ship a replacement free of charge.

Because every item is made to order, whether from your own file or from a model in our shop, you can only cancel your order within 12 hours of placing it. Once printing has started, we cannot accept cancellations.
