Lost-wax casting planner
Open a 3D model of your piece and Alchemy Cast builds the sprue tree for your flask, metal and casting method. Then it walks you through the whole casting day: investment, burnout and kiln program, alloying, the job quote, and a log of every cast.
Tap a number to see every product you can pick, or search all 151.
Why Alchemy Cast
Alchemy Cast does the measuring, sizing and maths for you, explains each step, and catches the mistakes that waste metal. Beginners can start with confidence, and experienced casters get their time back.
How it works
The Setup Wizard asks about your pattern, investment, flask, metal and casting method, then sets up every page to match. Change anything later and the rest follows.
STL, OBJ or 3MF. Load several parts, each with its own quantity, to cast them in one pour.
Auto-sprue sizes the feeds, trunk and button and lays the pieces out in the flask with safe clearances.
Powder and water amounts, a mix timer, the burnout chart and a kiln program in your controller's own words.
Weigh the tree for the metal you need, then log the result. The troubleshooter helps when a cast goes wrong.
Features
Tap any picture to see it full size.
Eight short steps from model to pour. It generates the tree and the burnout plan in one go, and Cancel puts every setting back.
Auto-sprue for centrifugal, vacuum or tilt casting. Then move, turn or scale any piece, add braces by hand, and the feeds follow. A 14‑rule tree check runs before you export.
Colours the model by thickness, flags spots too thin to fill, and checks the feed meets the heaviest section. Shrinkage scaling and a ring sizer in US, UK or EU sizes keep rings true, even for a whole size run.
Export the tree as STL or 3MF for a resin printer, or print a build sheet with a cut list matched to standard wax wire and rod.
12 investment powders from 4 makers, the powder and water for any flask, a mix timer, and a plan worked backwards from when you want to pour.
Your cycle as segments for 12 kiln controllers, in the words the display shows, with the key presses to enter it. Print it to keep by the kiln.
Pick from 29 stones to see which survive the burnout. The cycle is held under the safe limit, with the sources for every figure.
Recipes for about 40 precious and base alloys, and a calculator that turns one into grams of each metal, with live spot prices.
Frame fit, cure times for 16 rubbers, master sizing for shrinkage, settings for 20 injection waxes, and a printable mold label.
Metal, investment, wax or resin, kiln energy, finishing loss and labour add up to a quote per piece, in your local currency.
Every cast with its settings, result and photos. After a few casts it learns your real melt loss and how your trees weigh against the estimate.
Pick what went wrong, such as porosity, incomplete fill or fins, and see the likely causes and the setting to change.
A catalogue of casting supplies with links to stores that serve your country, plus a safety checklist and a reading list.
