Cu MiniForm XL Power Supply for Electroforming Copper | 5 Amp | Small Compact Jewelry Rectifier

MicroDean Systems

Regular price $184.99


The Cu MiniForm (as seen on demo at Maker Faire Bay Area and in MAKE magazine) has been upgraded to the Cu MiniForm XL! This is a power supply exclusively created and designed for electroforming to use in place of a bench power supply, which is a bloated piece of equipment for the task.

⚡ This “plug and play” power supply takes the guesswork out of fiddling with a clunky bench power supply. Great for both beginners and experienced electroformers!

⚡ Simply use the +/- buttons to set the amps you've calculated for your piece

⚡ 0.10 - 5.00 amp output

⚡ Great for small to large jewelry and figure projects (up to 50 square inches in a single tank)

⚡ US/North America USB-C wall adapter with USB cable included. A wall adapter is required for international orders(not provided)

⚡ Includes a set of -/+ lead wires

⚡ Small and compact Cu MiniForm XL measures at just 1 x 2 x 3 inches

Step by Step Electroforming Tutorial booklet provided


⚡The Cu MiniForm XL offers a unique feature called  milliRamp, which improves the deposit of the initial layer of copper. The Cu MiniForm XL will gradually increase the current depending on the conductivity of the paint and progress of the copper deposition until the set current level is reached. This will prevent over-plating of the suspension wire and initial copper layer while in the early stages. 

🇺🇸 Everything except the discrete components of the Cu MiniForm XL are designed, fabricated, programmed, and hand assembled in the U.S.A. by Mike Smith of MicroDean Systems.

This listing is for the stand alone power supply device (aka rectifier), to use with your own electroforming supplies, or the Electroforming Starter Kit.

Shipping Information

Do you ship internationally? 
For jewelry items, yes, I ship to most countries(sadly, excluding Brazil). International shipping generally takes 2-3 weeks to arrive for first class mail. 
For Electroforming Kits, and any supplies that contain liquid chemicals, I can only ship to the continental United States and Canada.

*Due to frequent requests, there are NO PRICES shown on packing slips

How much does shipping cost?
Shipping/packaging rates are based on your location, the shipping speed you select, and how many items are in your order. 
For Electroforming supplies, the price will vary depending on the item selected and your location. There is a shipping calculator at checkout.

How long will it take for my order to ship?
All items are made by hand to order, so please keep in mind that orders can take 3 to 7 business days to create before shipment. 
Please understand that October through December are my busiest times of the year, and I am a very small business of just one person that makes and ships everything!

How long will it take for my order to arrive after shipment?
Jewelry orders for ground advantage packages within the United States take 3-5 business days for arrival, and international packages take business 2-3 weeks(or longer- depending on your country's customs inspection). Priority Mail within the United States takes 2-3 business days, and International Priority Mail takes 6-10 business days. Express mail take 1-3 business days in the United States, and International Express can take 3-5 business days.
Electroforming Kits and supplies that contain liquid chemicals must be shipped via UPS Ground, which is very slow and can take a week or longer, depending on your location.


I need this item to arrive by a certain date, will I get it on time?
You will be able to choose the method of shipping during checkout. Please keep in mind that all items are made to order and require processing time, especially during the holidays. This processing time is in addition to the estimated shipping arrival times. Please see the Holiday Shipping Deadline page for further details. 

Where is my order?
Please use the tracking number provided in the shipping notification email sent through stamps.com, or also found in your order details under "my account". For international orders, your package may be held in your customs office for inspection, which can result in 4 weeks-4 months of delay. Contact your local post office with the tracking/customs number so that they can provide you with release information. For orders in the US, delay could be a result of a problem with your address provided, a forwarding on your mailing address, or your local post office could be holding for pick up. If the tracking information seems to have stopped after a certain date, please contact your local post office with the tracking number.


I live in a city near you, can I do a local pick up? 
Enchanted Leaves is a small business that is currently run out of my home, not in a public shop or business office, so unfortunately I do not offer this option. 
However, I do shows in Southern and Northern California a few times a year. You are more than welcome to come to one of the shows to pick up your order. Check the show schedule to see if there is an upcoming show in your area.
