The size of the public version is fixed, but we can also order special sizes according to your requirements... Special sizes are not troublesome, but more expensive. Because we use relatively large aluminum plates to cut, the remaining material is useless, so the material cost of the aluminum plate will be calculated based on the relatively large aluminum plate, and the cost is relatively high. If you tell us your file pixels and the size of the work you want to make, we can suggest the most cost-effective cutting size according to your needs! In addition, the cut part needs special processing, and we will also charge for cutting! We have found many manufacturers and tried many methods. At present, we are dealing with the cutting part in the most suitable way (processing quality vs. cost) that we can find. However, local cutting is not as good as the whole batch of CNC cutting from the original American factory. The cutting is accurate. If you cannot accept a little error, it is recommended to print the original factory size.
