The E1 made UV printing accessible to a lot of people who were never going to buy a flatbed. Good machine. The blanks situation around it is the expensive part, and it does not have to be.
The per-unit problem
eufyMake sells a ceramic coaster blank pack for its own machine. Ten pieces, around $112 at the time of writing. That is roughly $11 per coaster.
They are good blanks. They are also printer-accessory priced, the same way printer ink has always been priced.
For comparison, a commodity sublimation ceramic coaster on Amazon runs about $1 per unit in a 40 or 50 pack. Those are a different product: glossy, coated for dye sublimation rather than UV, and the white underneath is often not actually white.
So you have an $11 option that is right for the process and a $1 option that is wrong for it. The useful answer sits in between.
What to look for instead
Three things, in order:
A genuinely bright white base. Hold the blank against a sheet of printer paper. If it reads cream or gray, every color you print will sit on that cast, and you will end up laying a white ink pass to fix it. White ink is your most expensive channel and your most clog-prone one. Skipping that pass is the single biggest saving available to you.
A matte UV coating, where the product needs one. Matte gives UV ink something to key into and kills glare. Needed on anything handled or wiped regularly, like a coaster. Not needed on something low-abrasion like an ornament.
Flat and rigid. The E1's bed is forgiving but flexing substrate costs you focus in the middle of the piece. Ceramic does not flex.
The blanks that fit
Ceramic coasters. 4 inch round or square, matte UV coating over bright white, cork already applied. $2.00 each, $1.80 at ten or more. Roughly a fifth of the OEM pack per unit, for a blank doing the same job.
Ceramic magnets. Six shapes, 2 to 2.75 inches, all the same thickness so you can gang mixed shapes in one pass. $1.25 to $1.50.
Ceramic ornaments. 3 inch round, hole drilled, gold string in every box. $1.75. Nothing else to source before a finished piece is ready to sell.
Car coasters. 2.6 inch with a finger notch, cork backed. $1.50.
Getting more out of each run
The E1 rewards batching just like any UV printer.
Gang small pieces. Magnets and car coasters are small enough to fit several at a time. Build a simple jig so placement is repeatable and save the layout file once.
Keep thickness consistent within a run. All our magnets share a thickness specifically so mixed-shape runs work without re-setting height.
Set height off the blank. Not the bed. On a thin blank that difference is the whole focus margin.
Check whether your workflow is adding white. A lot of default profiles lay white under color automatically. On a bright white ceramic blank you do not need it, and turning it off is faster and cheaper on every single piece.
A sensible first order
If you are starting out and want to find what sells without over-committing:
- 10 coasters, mixed round and square
- 10 magnets, mixed shapes
- 10 ornaments, if it is anywhere near Q4
Thirty pieces, well under fifty dollars, and ten or more of any one product earns 10% off automatically. Print them, take them to one market, and let the table tell you what to buy deep.
That is a cheaper education than a $112 ten-pack.
