@Jkao I tried the EP9009 last night on a small lego train track print. I printed it twice and intentionally snapped apart the first print. Today I printed a toothpaste squeezer. For all prints I used 20% plasticizer by weight. I was using MJG+ Red with 0.5% black dye by weight. Exposure was 6x base for 100µm layer.
My experience:
• The part was a small Lego-like railroad track with cross-ties about 2mm x 8mm x 25mm.
• The surface has a nice hard ABS feel to it. The edges are crisp.
• There is some increase in flexibility, but when stressed to failure the part suddenly shears — no transition. The fractured surfaces were very sharp and glassy. Judging by feel alone there does seem to be some more strength until failure. But not a huge difference.
• I dropped the part to let it shatter on a tile floor. From 4ft the part wasn’t damaged at all. Dropped from 8ft, the part shattered into a few pieces.
My thoughts so far:
• Probably not adequate for functional prototyping.
• It would be good for display models that get handled and need a little extra strength to maintain sharp edges, finish, and features.
Cost for me was
$32 qt + $15 shipping = $47 total
