What your manufacturing engineer actually checks
What your manufacturing engineer actually checks
Real production materials, no hard tooling
Freeform Injection Molding prints a sacrificial mold in xMOLD resin, you inject the actual production feedstock into it, then dissolve the mold away to release the part. You get end-use material properties without cutting steel — Nexa3D cites tooling cost down around 96% and CAD-to-part in roughly two days.

About this product
The Nexa3D Freeform Injection Molding (FIM) Desktop Package runs a tooling-free injection workflow: print a dissolvable mold in xMOLD resin on the XiP printer, inject your real production material into it, then dissolve the mold away to release the part — end-use material properties without cutting steel.
Why manufacturers run FIM
Injection-molded parts from a printed, dissolvable tool.
Real materials, no hard tooling
Inject the actual production feedstock into a printed xMOLD mold instead of machining steel. Nexa3D cites tooling cost down around 96% and CAD-to-part in roughly two days — production properties at prototype speed and cost.
Geometries steel can’t demold
Because the mold dissolves away, you can produce undercuts, internal channels and overmolded features that a two-part steel tool could never release — designs that were previously impossible to injection-mold.
Inject any conventional feedstock
Thermoplastics, TPE, liquid silicone rubber (LSR), MIM metals, CIM ceramics and composites — including reinforced grades. Mold in the real material and the part performs like a molded part, not a resin stand-in.
A desktop workflow
Built around the Nexa3D XiP desktop printer with xMOLD resin and an xWASH FiM Wash+Cure + demolding station — the printing, curing and mold-dissolving side of FIM in one package.
How Freeform Injection Molding works
Print the mold, mold the part, dissolve the mold.
Step 01
Print the mold
Print the sacrificial mold in xMOLD resin on the XiP (build 195 × 115 × 210 mm), then wash and cure it in the xWASH FiM station. xMOLD withstands up to 400 °C.
Step 02
Inject the material
Clamp the mold in an injection press and inject your production feedstock — compatible with pressures up to 2500 bar and melt temperatures up to 450 °C.
Step 03
Dissolve & release
Immerse the mold in an alkaline bath in the xWASH FiM station; it dissolves over roughly 12–48 hours, releasing the finished part — no manual tool disassembly.
Where FIM fits
Between one-off printing and committing to steel tooling.
Bridge & low-volume production
End-use material, no hard tool
Undercuts & internal geometry
Dissolvable-mold freedom
Overmolding
Around inserts & substrates
Functional prototypes
In the real production material
LSR silicone parts

Unedited feedback from manufacturing and R&D leads.
★★★★★
We bridged a 300-part run in the real thermoplastic without cutting a steel tool. Mold printed overnight, dissolved out clean — parts in two days.
MF
Marcus Feld Manufacturing Engineer · Industrial manufacturing
★★★★★
The undercuts on our part would never demold from a two-part tool. Dissolving the xMOLD mold made a geometry we could not injection-mold any other way.
PA
Priya Anand Product Engineer · Medical devices
★★★★★
Being able to inject LSR silicone and MIM metal from the same desktop workflow changed how we prototype end-use parts.

Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
What is Freeform Injection Molding (FIM)?
FIM is a workflow that replaces hard tooling with a 3D-printed, dissolvable mold. You print the mold in Nexa3D xMOLD resin on the XiP printer, clamp it in an injection press, inject your real production material, then dissolve the mold away in an alkaline bath to release the finished part. It brings injection-molded material properties to complex, low-volume parts without the cost and lead time of steel tooling — Nexa3D cites tool cost down around 96%.
What is included in the Desktop Package?
The Desktop Package is built around the Nexa3D XiP desktop printer (195 × 115 × 210 mm build, up to 180 mm/hour) and includes xMOLD dissolvable mold resin (5 kg, withstands up to 400 °C), an xWASH FiM Wash+Cure station (46.2 L, demolding up to 85 °C), the XiP building board, and a 1-year service plan. An injection press is required to mold the parts — Additive Plus confirms the right press for your Desktop setup at quote.
Do I need a separate injection press?
Yes — FIM prints and dissolves the mold, but a small injection press is what injects your production material into it. The Desktop Package covers the printing, resin and demolding side; the press is configured with it. A desktop unit such as the APSX-PIM pairs with this workflow — an Additive Plus engineer will confirm the press and shot size for your parts and materials at quote.
What materials can I inject?
FIM works with conventional injection-molding feedstocks — thermoplastics, thermoplastic elastomers (TPE), liquid silicone rubber (LSR), metal injection molding (MIM) metals, ceramic injection molding (CIM) ceramics and composites, including reinforced grades. Because you mold in the real material, the part has production-grade properties rather than a resin approximation.
How does the mold dissolve, and how long does it take?
After molding, the xMOLD mold is gently immersed in an alkaline water solution in the xWASH FiM station and dissolves away over roughly 12–48 hours, releasing the finished part with no manual tool disassembly. This is what lets FIM produce undercuts and internal geometries a two-part steel mold could never release.
What geometries and tolerances can it achieve?
FIM molds resolve fine features starting around 10 µm with part tolerances in the 10–80 µm range, and are compatible with injection pressures up to 2500 bar and melt temperatures up to 450 °C. xMOLD itself withstands up to 400 °C. That covers complex internal channels, undercuts and overmolding that conventional tooling cannot demold.
Who is FIM for?
It suits bridge and low-volume production in end-use material, functional prototypes that must be the real material, complex or undercut geometries, overmolding, and low-volume tooling inserts. It is a fast, low-cost path between one-off printing and committing to hard injection-mold tooling.
What is the lead time and what does Additive Plus include?
The FIM Desktop Package is configured and quoted to your setup, including the injection press. Additive Plus includes install and operator training and supports mold design, injection and demolding, with xMOLD resin, spares and service through a single US point of contact.
