About this product
xMOLD is Nexa3D’s dissolvable resin for Freeform Injection Molding (FIM). You print the mold on an LSPc printer, inject a real production thermoplastic into it, then dissolve the mold away in solvent — getting injection-moulded parts in production material without cutting steel tooling.
Why engineers use xMOLD
Injection-moulded parts without the tooling lead time or the tooling bill.
Tooling in hours, not weeks
Print the mould on a Nexa3D LSPc system and inject the same day. Design changes go back through CAD, not back through a toolmaker.
Real production materials
xMOLD is compatible with thousands of commercially available injection moulding materials, including reinforced and high-performance grades — the polymer you will actually ship.
Geometry steel tooling fights
The mould dissolves completely, so undercuts, internal channels and trapped features release without side actions or a complex parting line.
No minimum order
Run a single part or a bridge batch. The economics work at quantities that never justify a steel tool, and scale up as demand proves out.
How Freeform Injection Molding works
Print, inject, dissolve — three steps from CAD to a moulded part.
Step 01
Print the mould
Print the mould cavity in xMOLD on a Nexa3D LSPc printer, then wash and post-cure it ready for the press.
Step 02
Inject production polymer
Mount the mould in a standard injection moulding machine and shoot your real production material, including reinforced grades.
Step 03
Dissolve and release
Submerge the assembly in demoulding solvent. xMOLD dissolves completely and frees the part — no ejection damage on delicate geometry.

Compatibility & workflow
- Printers: Nexa3D LSPc systems — the XiP desktop for the standard FIM workflow, and NXE-series industrial printers where larger or more numerous moulds are needed.
- Injection materials: compatible with thousands of commercially available injection moulding polymers, including reinforced and high-performance grades. Confirm your specific grade with our engineers before a first run.
- Supporting equipment: a standard injection moulding machine, a Nexa3D wash-and-cure station, and an xWASH FiM demoulding station for dissolving the mould. Nexa3D Mold Generator software builds the mould geometry from your part CAD.

Unedited feedback from engineers using xMOLD tooling.
★★★★★
We got moulded parts in our production grade three days after CAD sign-off. The steel tool quote was eleven weeks.
NB
Nikolai B. Product Development Engineer · Medical devices
★★★★★
The undercuts on our housing would have needed side actions in steel. The mould just dissolves and the part comes out clean.
CM
Clara M. Tooling Engineer · Industrial equipment
★★★★★
Being able to test a glass-filled grade at fifty parts, before committing to tooling, changed how we scope programmes.

Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
What is Freeform Injection Molding and how does xMOLD fit in?
Freeform Injection Molding (FIM) replaces machined tooling with a printed, dissolvable mould. You print the mould cavity in xMOLD on a Nexa3D LSPc printer, mount it in a standard injection moulding machine, inject your production thermoplastic, then dissolve the mould away in demoulding solvent. The result is a genuinely injection-moulded part in production material, without cutting steel.
Which injection molding materials can I use with xMOLD?
Nexa3D states xMOLD is compatible with thousands of commercially available injection moulding materials, including reinforced and high-performance grades. Because processing windows vary widely between polymers, confirm your specific grade and melt temperature with our engineers before a first run rather than assuming compatibility from the general claim.
Which printers can print xMOLD moulds?
xMOLD prints on Nexa3D LSPc systems. The XiP desktop runs the standard FIM workflow and is what most teams start with; NXE-series industrial printers handle larger moulds or higher mould throughput. Nexa3D Mold Generator software builds the mould geometry from your part CAD, so you are not designing tooling by hand.
What equipment do I need besides the resin and printer?
You need a standard injection moulding machine, a wash-and-cure station to post-process the printed mould, and an xWASH FiM demoulding station to dissolve the mould after injection. Mold Generator software is used to create the mould from your part CAD. Additive Plus supplies all of these, so the FIM chain comes from one partner.
What are the mechanical properties of cured xMOLD?
Post-cured xMOLD reaches 38 ± 3 MPa ultimate tensile strength, a Young's modulus of 1152 ± 284 MPa, 31 ± 2 MPa tensile stress at break, toughness of 18 ± 4 MPa and Shore 80 D hardness, with a thermal conductivity of 0.187 W/m·K. These describe the mould itself — the part you produce takes the properties of the injected polymer, not of xMOLD.
How does FIM compare to steel tooling on cost and lead time?
FIM turns a mould around in hours rather than the weeks a machined tool takes, and there is no minimum order — a single part is viable. It wins at prototype, bridge and low-volume quantities, and on geometry that would need side actions in steel. Steel still wins once volumes are high enough to amortise the tool. Send us your part and batch size and we will tell you honestly which side of that line you are on.
How should xMOLD be stored and handled?
Keep xMOLD sealed, away from direct light and heat, at room temperature. Handle uncured resin with gloves in a ventilated area, and follow the safety data sheet for the demoulding solvent as well as the resin. Sealed and stored correctly, xMOLD keeps its printing characteristics through its shelf life; mix gently before use if it has been standing.
