SlapChop Bundle: Hero HD Merchant Grey 2.5 kg and InstantEffect 10 Color Box Set

Print your minis, paint them, and get them on the table. This bundle gets you a 2.5 kg jug of Hero HD Merchant Grey (The Table Gamers' Resin™) and the full 10 color InstantEffect™ One Coat Color and Shade Box Set for $139.90.

Bought separately, that's $239.90. You save $100. The resin alone is $159.95, so the bundle actually costs less than the jug by itself. That's essentially getting the paint set for free. It also works out to about $56 per kg of resin. And if you're in the lower 48, Standard shipping is free. We offer free Standard shipping in the lower 48 on orders of $44 and up.

This is a November 2026 offer only, and only while supplies last. The 2.5 kg jugs are limited, and once they're gone, so is the bundle.

What you get

• 1 jug of Hero HD Merchant (Dark) Grey, 2.5 kg (label reads HHD9). It's a deep, dark blue shade of grey that makes every detail pop, and it's our most popular color for Merchant printers. Regular price $159.95.
• 1 InstantEffect™ One Coat Color and Shade Box Set. Ten bottles, 30 ml (1.0 fl oz) each, water based, made to go directly on the surface. Regular price $99.95, currently $79.95.

The ten colors are Void Black, OxBlood, Jade Sapphire, Troll Hide, Ultra Violet, Pure Yellow, Pure Red, Cyan Rift, Bog Oak and DryBrush White.

The resin

Hero HD was made for tabletop miniatures, terrain and gaming pieces that actually get played with. It's built to handle being picked up, dropped, packed in a bag and used again, without losing sharp detail.

• It's tough and a little flexible. Elongation is 30 to 35%, so weapons, fingers and thin walls bend instead of snapping.
• Shore D hardness is 77, so a cured print feels solid in your hand.
• It prints on 365 nm, 395 nm and 405 nm printers. Viscosity is 550 to 650 cP, which flows well and holds detail on busy builds.
• Linear shrinkage is under 1%, and it takes paint well.

The Hero HD line is also thermally curable, and that part is up to you. Curing with heat makes prints tougher and cleaner, and it's becoming the preferred method for Merchant printers. Cure it with UV or heat. For heat, run it at 215 to 275°F for a minimum of one hour.

The paint

InstantEffect™ goes straight onto your print. Brush it on and you get color and shading in the same pass, because it settles into the recesses and brings out the detail you printed. Thicker areas give you more depth, and thin layers give you finer detail. There's no priming and no layering unless you want it.

Three ways to paint, all in one box

1. Contrast. Brush the colors straight onto the print and get color and shading in one coat. For SlapChop, the Contrast method with DryBrush White, dry brush DryBrush White over your print first to pick out the raised detail, then brush the colors over it. That's the method this bundle is named for.
2. Traditional. Blend DryBrush White into any color to make more traditional opaque colors like flesh tones and pastels.
3. Airbrush. Run the colors through your airbrush undiluted to paint or prime models fast without clogging the nozzle. Keep DryBrush White for brush work.

• 3DRS makes the resin, so we know what paint has to do to stick to a smooth printed surface. It works on resin prints, FDM models, minis and terrain.
• It's meant for people who want the squad finished tonight, not next month.

What customers say about InstantEffect™

"I definitely see myself skipping priming and going straight to base coating. The black was easily the best coat over a large surface I've ever painted." Travis T., 5 stars

"I print thousands of miniatures a month, but this is my second painting attempt EVER. I used these awesome paints from 3DRS and look at the results. Sure I need a little practice, but it looks great! No primer, no wait for things to dry and put on another coat, just paint it on and show it off!" Douglas J., 5 stars

"I only have one color so far but I already ordered the rest of them! Super easy to use and goes on like a dream!" Dawn R., 5 stars

On the resin side, the reviewer Variance Hammer looked at the original HERO resin and called it "a really great, high performance resin" with solid detail and real durability on thin, bendy parts.

Paint Safety and Handling

• InstantEffect paints are water based acrylics, made for hobby and miniature painting.
• Adult supervision is needed when children use these paints. Keep them out of reach of young children.
• When airbrushing, work in a well ventilated area, ideally with a spray booth. Wear a respirator or mask rated for paint mist so you do not breathe the spray.
• Avoid contact with your eyes. If paint gets in, rinse with clean water and get medical help if irritation continues.
• Wash with soap and water after handling, and before eating or drinking.
• Do not eat or drink the paint. If swallowed, rinse your mouth with water and call a doctor or poison control.
• Clean brushes and airbrushes with water before the paint dries.
• Keep caps closed tight. Store at room temperature, away from heat and freezing.
• Dispose of leftover paint and empty containers following your local rules. Please do not pour large amounts down the drain.

Questions people ask

• Will it work on my printer? If your printer cures at 365, 395 or 405 nm, yes.
• Do I need primer? No. InstantEffect™ is made to go directly on the surface.
• Can I use an airbrush? Yes. It's one of the three methods in the box. Just don't thin the colors, and keep DryBrush White for brush work.
• Is a flexible resin harder to print? A little. Longer supports can flex, so brace them. In return your minis bend instead of breaking.
• Is it safe to handle? Treat it like any resin. Wear nitrile gloves and goggles, work with good ventilation, and clean prints with high purity IPA or Rhino Resin Cleaner. Don't use prints for food contact, and keep them away from anyone who might chew on them.
• What about shipping? If you're in the lower 48, Standard shipping is free. We offer free Standard shipping in the lower 48 on orders of $44 and up.
