This is because 3D-printing machines and resins are predominantly a foreign industry. China is by far the largest player in 3D-printing machine and resin manufacture.

Affordable, commercial-grade printers just aren't made here in the US nor are most resins suitable for scale models. A few do exist but it's not a big thing here.

Any US vendor who relies on foreign-made machines and resins (as we do), can easily be badly impacted by any imposition of tariffs or supply disruptions.

We got through the Brexit and EU VAT messes, then Covid, by the skin of our teeth. Now this tariff and supply disruption mess is really shaking us hard.

As of this writing, we are having trouble obtaining the repair parts we need to keep our printers operating.

Hopefully, with the support of our valued customers, we'll get through this mess, too.
