wonderpress vacuum forming guide and 3d sublimation
xTool WonderPress 3D sublimation process creating full-wrap personalized phone cases

Flat heat presses work well for shirts, tote bags, plaques, and other two-dimensional blanks. The xTool WonderPress expands beyond those conventional applications with a 3D Form Module built for full-wrap 3D sublimation and small-format vacuum forming.

That means one modular platform can decorate curved phone cases and dimensional blanks, then switch workflows to form plastic sheets over physical masters for molds, packaging, resin projects, candles, bath products, and other custom goods.

What does the 3D Form Module do?

It supports two different processes. In 3D sublimation mode, heat and vacuum wrap printed sublimation film around a compatible coated blank. In vacuum-forming mode, heat and vacuum shape a plastic sheet over a physical master to reproduce its three-dimensional form.

Two 3D workflows in one WonderPress module

Mode 1

3D sublimation

Printed sublimation film is heated until it softens, then vacuum pressure draws it tightly around a compatible coated object.

  • Decorates the final product
  • Creates wraparound coverage
  • Best for compatible coated or polymer blanks
  • Common for phone cases, badges, and keycaps
Mode 2

Vacuum forming

An unprinted forming sheet is heated and pulled over a physical master, then cools into a new three-dimensional shape.

  • Creates molds, trays, packaging, and shells
  • Replicates the shape of a master object
  • Uses PETG, HIPS, TPU, or other compatible sheets
  • Finished form may be used for casting or packaging

How xTool WonderPress 3D sublimation works

Traditional sublimation usually presses a printed transfer against a flat sublimation-coated surface. Three-dimensional objects are more difficult because a flat platen cannot maintain contact around curved edges, corners, and recessed areas.

WonderPress approaches the problem by heating printed 3D sublimation film until it becomes flexible. The integrated vacuum system then draws the film around the object so the printed surface stays in close contact with its curves during transfer.

1

Prepare the artwork

Size, mirror, and print the design using compatible sublimation ink and 3D sublimation film.

2

Position the blank

Place a compatible sublimation blank on the correct support, fixture, or mold.

3

Load the film

Position the printed film over the blank and secure it promptly with the sealing frame.

4

Heat the film

WonderPress softens the film using the selected 3D sublimation parameters.

5

Apply vacuum

Vacuum pressure pulls the softened film around the dimensional blank and its edges.

6

Cool and remove

Allow the item to cool before removing the film and inspecting the finished transfer.

Compatible blanks still matter A 3D sublimation heat press cannot make ordinary untreated plastic accept sublimation ink. The blank must use a compatible polymer or sublimation-ready coating, and it may require a supporting mold or fixture designed for its shape.

What can you make with WonderPress 3D sublimation?

WonderPress is particularly well suited to smaller dimensional items that fit within the 3D Form Module and can be securely supported during transfer.

  • Full-wrap phone cases: transfer artwork around the back, edges, and corners of compatible cases.
  • Button badges: apply printed film across curved badge faces.
  • Keycaps: create customized keyboard sets using compatible sublimation-ready blanks.
  • Dimensional promotional products: decorate small compatible items that cannot be pressed evenly with a flat platen.
  • Curved gift products: personalize compatible coated blanks with edge-to-edge graphics.

From a physical shape to a reusable mold

Vacuum forming creates a new shell or mold around a master object for compatible casting applications.

How the WonderPress vacuum-forming process works

A conventional vacuum forming machine heats a thermoplastic sheet and uses negative pressure to pull it tightly around a master form. WonderPress uses the same basic principle in a compact craft-oriented module with an integrated vacuum pump and film-temperature monitoring.

1

Select a master

Choose an object with a shape that can release from the formed sheet after cooling.

2

Choose the film

Match PETG, HIPS, TPU, EVA, or another approved sheet to the final use.

3

Center and clamp

Keep the sheet margins even so the softened film remains sealed during vacuuming.

4

Heat the sheet

The sheet softens while the infrared system monitors the material temperature.

5

Form the shape

Vacuum pressure pulls the softened sheet over the master and reproduces its detail.

6

Cool and demold

Let the sheet stabilize before removing the master and trimming the finished form.

Avoid severe undercuts Bottle necks, hooks, wide tops over narrow bases, and deep side recesses can lock the master inside the cooled form. Choose objects with a practical draft angle—typically narrower toward the top and wider toward the base—to make demolding easier.

WonderPress vacuum-forming and sublimation film guide

Material Primary use Characteristics Example applications
PETG General vacuum forming Rigid, clear, and suitable for reproducing detailed shapes Packaging, trays, shells, general-purpose molds
HIPS Molds and packaging Rigid material that can be painted or colored Product packaging, craft molds, display forms
TPU Flexible vacuum forming Soft and flexible after forming; requires careful sealing and alignment Flexible molds, protective shells, soft formed parts
3D sublimation film Dimensional image transfer Printed with sublimation ink and wrapped around compatible blanks Phone cases, badges, keycaps, coated dimensional products
EVA Flexible mold applications Can be used for applications such as ice molds; not currently sold by xTool Ice shapes and other approved flexible-mold uses
Beginner TPU recommendation xTool recommends that beginners start with 1 mm TPU rather than thinner 0.5 mm material. Thinner TPU can sag more during heating, pull away from the seal, and increase the risk of vacuum failure.

What can you make with a compact WonderPress vacuum former?

The final product is often not the vacuum-formed sheet itself. In many cases, the formed sheet becomes a mold, tray, package, or production tool used to make another item.

Additional vacuum-forming product ideas

  • Custom candle molds
  • Soap and bath-product molds
  • Resin jewelry and keychain molds
  • Plaster and decorative casting forms
  • Product trays and blister-style packaging
  • Miniature shells and model components
  • Protective inserts for small products
  • Chocolate or food molds made only from verified food-contact-safe materials
  • Ice molds made from an appropriate approved sheet
  • Clear dimensional pockets for paper crafts and shaker cards
Confirm material safety for the final application Do not assume every forming sheet is food-safe, skin-safe, heat-safe, or compatible with every casting material. Verify the sheet manufacturer’s specifications before using a form with food, cosmetics, candles, hot resin, or other regulated applications.

Related WonderPress workflows beyond the 3D Form Module

Some dimensional products associated with WonderPress use the Craft Oven rather than the 3D Form Module. Heat-bent acrylic, dried-flower crafts, shrink plastic, and polymer-clay projects are Craft Oven applications and should not be confused with vacuum forming.

What to know before buying

1. The 3D Form Module is an optional workflow module

Confirm that the WonderPress package you select includes the 3D Form Module. The standalone Heat Press package does not automatically include vacuum-forming or 3D sublimation hardware.

2. Blanks, films, and molds are part of the workflow

The machine provides heat, vacuum, sensing, and control. Successful results still depend on choosing a compatible forming sheet or sublimation film, the correct master shape, and a suitable blank, fixture, or mold.

3. Film placement affects vacuum sealing

Center the forming film so its front and rear margins are as even as possible. When TPU heats, it can sag and contract toward the middle. Uneven placement can allow one edge to pull free and break the vacuum seal.

4. Deep undercuts make demolding difficult

A vacuum-forming sheet wraps around the master. Shapes that become wider above a narrow base can mechanically lock inside the finished form.

5. Test before running production

Time, temperature, vacuum pressure, sheet thickness, object height, surface geometry, room airflow, and material source can all affect the result. Test a sample before processing a full batch.

xTool WonderPress 3D sublimation and vacuum-forming FAQ

Can WonderPress sublimate ordinary phone cases?

No. The case must be designed for sublimation or use a compatible sublimation-ready coating or polymer. A suitable fixture or mold may also be required.

Is WonderPress a phone case heat press?

The 3D Form Module can support a dimensional phone-case sublimation workflow, but it is broader than a dedicated phone case press because it also supports vacuum forming and other compatible 3D products.

Does the 3D Form Module require an external vacuum pump?

No. The WonderPress 3D Form Module uses an integrated vacuum system, so an external pump and loose vacuum hoses are not required for standard operation.

What materials can be vacuum formed?

xTool lists PETG, HIPS, and TPU for different forming applications. EVA can also be used for appropriate mold applications, although xTool does not currently sell it.

Can WonderPress make candle, resin, or soap molds?

The module can form compatible plastic sheets over suitable master objects. The resulting form may be used as a mold if the sheet is compatible with the intended casting material, temperature, and safety requirements.

Why does TPU sometimes fail to form?

Common causes include uneven film placement, insufficient edge sealing, excessive sagging, an unsuitable film thickness, incorrect heating, or a master object with difficult geometry.

Is WonderPress a replacement for an industrial vacuum-forming machine?

It is designed for compact products, crafts, personalization, molds, and packaging projects. Large-format or continuous industrial forming applications require larger dedicated equipment.
