SAM Bodycasting.com
A hand that will be exactly the same in thirty years.
From baby fingers to grandpa's hand. Stir the seaweed gel, hold still until it changes from bright pink to white, then pour plaster. After half an hour, you'll have a cast where you can see the fingerprints.
One for adult hands, one for babies and children. No experience needed.
Which set do you need?
The difference lies in the quantities and mixing cups. The materials in both sets are the same: 3D Gel made from alginate and 3D Plaster.

Still unsure? The Kids set is not suitable for adult hands — the largest mixing cup won't fit around them. Conversely, the regular set can be used for a child's hand, but you'll have leftover material.
The whole process takes one morning
The longest wait is for the plaster to cure. The rest is stirring and holding still.
5½ min
The 3D Gel is ready to demould at 21 °C with cold tap water. You'll see it by the color: from bright pink to white.
30 min
The 3D Plaster in the mold is hard enough to demould. Full strength after eight hours.
Permanent
The plaster sculpture remains. The gel mold is single-use and can go in organic waste — it's dried seaweed.
How to make a cast
The ratio for the gel is four parts water to one part 3D Gel. So, 500 grams of gel goes into 2000 grams of water. The same steps apply to both sets; only the quantities differ.
-
Weigh water and add gel
Fill the cup with cold water and pour in the 3D Gel all at once. The mixture will turn bright pink. Cold water gives you the longest working time — with lukewarm or warm water, it hardens noticeably faster.
-
Mix, but briefly
Use an electric mixer or a drill with a stirring rod until the mixture is smooth. Maximum forty seconds; after one minute, the gel begins to set. Stirring by hand will result in lumps.
-
Insert hand and hold still
Move the hand slightly back and forth to allow air bubbles to escape, then hold it completely still. Let the fingers touch the palm; fingers hanging loosely in the air will trap air and result in incomplete fingertips later.
-
Remove hand when gel is white
Take your time with this. First, gently move the hand up and down to release the vacuum. The gel is strong and elastic; small cracks are not a problem, but do not pull.
-
Prepare and pour plaster
Four parts 3D Plaster to one part water. First, fill the mold halfway and gently tilt it around so the plaster reaches everywhere. Pour within half an hour — if you wait longer, the organic mold will lose detail.
-
Demould and finish
After half an hour, tear away the gel mold. Remove gel residues with a skewer and tweezers, and remove bumps with a sharp knife or fine sandpaper. After 48 hours, you can paint or wax the sculpture.
With a child, it works a little differently
Three minutes feels like a long time when you're four. Most of the result is determined before you even touch anything.
That's why the Kids set includes a rubber duck: a baby looking at something keeps their hand still. And that's why there are three mixing cups instead of one — a baby's hand in too large a cup will hit the edge and result in a partial impression.
Five things that make a difference
- Practice the position first with the empty cup, so the child knows what to expect
- Choose the cup where the hand fits comfortably without touching the rim
- Lukewarm water feels more pleasant for a baby, but hardens faster — work more quickly
- There's enough material for at least two attempts. The first time usually works, but don't panic
- For small hands, feel free to wait longer than half an hour before demoulding — fewer fingers will break off
How much material do you need?
Weigh according to your set's table, and you won't have any leftovers.

Not every hand posture works
Postures where fingers hang loosely in the air trap air. You'll only notice this when demoulding, when the fingertips are missing. Let the fingers touch each other or the palm.
Allergy information: 3D Gel may contain traces of crustaceans. Otherwise, the gel is biodegradable and, as far as is known, harmless to humans and the environment. In case of contact with eyes, rinse with water.
If something goes wrong
The sets are simple, but these seven things are most frequently asked by our customer service.
There are lumps in my gel mixture
Stirring by hand is not enough. Use a kitchen mixer, or better yet: a drill with a stirring rod. Small lumps are generally harmless, by the way.
There are many air bubbles in the mixture
Mixing at high speed incorporates air. Hit the side of the cup with your flat hand and rotate it quickly left-right; the bubbles will rise to the surface.
The gel hardens too quickly
Lukewarm or warm water drastically shortens the working time. Use cold tap water. For a baby, lukewarm water is more pleasant — but work faster then.
There is water in my mold
Alginate releases absorbed water over time. Therefore, pour as soon as possible after demoulding. If there is water at the bottom, tip it out before pouring the plaster.
Fingers break off during demoulding
The plaster can be demoulded after half an hour, but only reaches full strength after eight hours. For small hands, waiting longer is always safer.
The plaster doesn't harden at all
Almost always too much water. The ratio is four parts plaster to one part water: for 1000 grams of plaster, use 250 grams of water, no more.
Can I cast something other than plaster?
Yes — silicone, acrylic resin, candle wax, or concrete can also be used. Mix the gel in a 1:3 ratio instead of 1:4. We strongly advise against polyurethane and most epoxy types: they do not tolerate the moisture from the gel.
