Water Washable Dental Model Resin for DLP & LCD Printers — No IPA Needed, High Precision Dental Models (1kg / 1,000ml)

Dental Model Resin for DLP & LCD Printer

This water washable dental model resin is designed for dental labs and clinics that print crown and bridge models, implant analog models, and diagnostic study models on DLP or monochrome LCD printers — and want a cleaner, cheaper, and faster post-processing workflow. The key difference from a standard dental model resin? You wash the printed model under running water instead of soaking it in isopropyl alcohol. That one change saves money on IPA, removes the fire and ventilation hazard of storing alcohol in your workspace, and cuts post-processing time significantly.

The model resin side of the equation is equally solid: low shrinkage formulation, high dimensional accuracy, and the stiffness needed for precise die trimming and crown fitting. Everything a dental model resin needs to do — just without the IPA bottle.

⚠️ Before You Print — Read This First

• Not for intraoral use. This is a dental lab modeling resin. It is used to create physical working models — it must never be placed inside a patient's mouth. Models printed with this resin are reference tools, not restorations.
• UV wavelength: Compatible with DLP and monochrome LCD printers in the 385–405 nm range. Verify your printer's light source before ordering.
• Water washable ≠ safe to touch uncured. This resin washes with water after printing, but uncured liquid resin is still a skin and eye irritant. Always wear nitrile gloves and safety glasses when handling uncured resin, during printing, and during the wash step.
• Post-curing is required. Water washing removes the uncured resin from the surface, but the model still needs UV post-curing to reach final hardness and dimensional stability. Do not skip this step.
• Do not over-wash. Leaving the model submerged in water for more than the recommended time can affect surface quality and dimensional accuracy. Short, efficient wash cycles give the best results.
• Shake before use: Mix thoroughly before pouring into the vat. Settled components cause uneven curing and color inconsistency across the build plate.
• Storage: Keep sealed below 25°C (77°F), away from direct light and heat. Do not store in direct sunlight — ambient UV will begin curing the resin in the bottle.

Water Washable vs. Standard Dental Resin — What Actually Changes in Your Workflow

Think of it this way: after you print a model, it comes out of the printer with a thin layer of liquid resin still coating the surface. With a standard dental resin, you need to remove that liquid by soaking the model in IPA (isopropyl alcohol) — which you then have to store safely, dispose of properly, and constantly restock. With this water washable resin, you rinse that same liquid off under the tap or in a bowl of water. Same result, none of the hassle.

Key Material Properties

• Water washable — no IPA or alcohol required: The most practical advantage for busy labs and chairside workflows. Eliminate flammable solvent storage, reduce consumable costs, and speed up the post-processing step without sacrificing model quality.
• Low shrinkage — models stay accurate after curing: The resin is formulated to minimize dimensional change during the UV post-cure step. This is critical for models that will be used to seat crowns, check margin fits, or hold implant analogs — any dimensional shift translates directly into a worse-fitting restoration.
• High surface detail reproduction: Captures fine anatomical features — margin lines, die contours, interproximal contacts — needed for accurate crown and bridge fabrication and diagnostic evaluation.
• Low viscosity: The resin drains off printed surfaces cleanly, which means less residual resin to wash off, a cleaner vat after printing, and less material wasted per build.
• Low odor: More comfortable to work with in enclosed environments — a meaningful quality-of-life improvement for chairside use or small office setups without dedicated ventilation.
• 1kg / 1,000ml format: Full production volume for high-throughput labs. Cost-effective per model at scale without the compromise of smaller trial sizes.

Dental Applications

• Crown and bridge working models with removable dies
• Implant analog models and multi-unit implant frameworks
• Diagnostic and study models
• Orthodontic staging and aligner base models
• Alveolar arch models for treatment planning
• Patient communication models

Technical Specifications

Recommended Print Settings

Water washable dental resins can behave slightly differently from IPA-wash resins on the same printer — the exposure time that works for your standard dental resin may need minor adjustment here. Run a calibration print first and verify dimensional accuracy on a reference model before committing to a full production build.

Post-Processing Instructions

1. Remove from build plate carefully using a metal spatula. Keep gloves on — uncured resin is still present on the surface at this stage.
2. Rinse under water immediately after removal. Use a soft brush or a dedicated ultrasonic cleaner filled with water to dislodge resin from fine detail areas — die sockets, margin lines, and interproximal spaces. Two short rinse cycles in fresh water are more effective than one long soak.
3. ⚠️ Do not over-soak. Prolonged water exposure can cause water absorption in the partially cured resin, leading to surface softening or dimensional changes. Keep total water contact time under the manufacturer's recommendation.
4. Air dry completely before post-curing. Use pressurized air to clear water from sockets, die holes, and recessed areas. Surface moisture during UV curing can create a hazy finish.
5. Post-cure under UV for the manufacturer's recommended time. This step hardens the model to its final mechanical properties and dimensional stability — do not skip it even though the surface already feels dry and solid after washing.
6. Trim, articulate, and verify on the articulator before use in crown fabrication or patient communication.

Who Is This Resin For?

This water washable dental model resin is the right choice if:

• You are a dental lab or in-office clinician printing working models, implant analogs, or diagnostic models and want to eliminate IPA from your post-processing workflow entirely.
• You work in a small office or chairside environment without dedicated solvent ventilation — water washable resins remove the fire hazard and odor of IPA-based cleaning.
• You are looking to reduce consumable costs — removing ongoing IPA purchasing and disposal from your workflow is a real operational saving at production scale.
• You own a 385–405 nm DLP or monochrome LCD printer and already have a UV curing station — the only additional hardware you need is a water wash basin or a standard ultrasonic cleaner filled with water.

This resin is NOT the right choice if you need a flexible or elastic material, or if you require a material validated for intraoral patient use.
