MVLscope WHY THIS MATTERS
MATERIALS PREPARATION · VIRTUAL LAB · ABOUT 20–30 MIN
From sample to micrograph.
Keep the question. Follow the evidence.
Opening the preparation workbench… The workflow outline and sources below remain available.
The specimen & support
A diagram is available when 3D cannot open.
The inspection image
Carry the preparation record with the image.
These links open instrument lessons. Your virtual specimen and notebook stay on this page; they are not transferred into another simulator.
Pores and inclusions
A suitably prepared, unetched cross-section can show pores and inclusions. Compare preparation histories; a single chosen section does not establish bulk porosity.
Learn SEM imaging ↗Elemental composition
Preserve the phase and document contamination, mounting media and any coating. A detector and suitable acquisition conditions are still needed; brightness alone is not an elemental identification.
Explore SEM / FIB ↗Original surface height
Sectioning and polishing create a new surface. Keep a separate intact specimen to investigate the original height or roughness.
Learn optical profilometry ↗Inside an electron-transparent section
TEM needs additional preparation, including a suitable thin region and control of damage. This bulk specimen cannot be transferred directly into TEM.
Learn TEM principles ↗INSPECTION NOTEBOOK
Compare what actually changed.
Checkpoints retain their picture, plane, surface state and history. Start a new virtual specimen to compare another preparation history.
Inspect the surface to keep your first checkpoint.

Workflow outline & learning goals
Begin with the Before the Image foundation lesson if sample preparation is new to you. This workflow teaches decisions and inspection. Use your facility’s procedures for real preparation.
Select a region
A section reveals only the features it intersects. Keep the sampling direction and location with the image. Changing the camera changes your view, not the section.
Support the specimen
Mounting can help retain fragile edges. Its suitability depends on the material and examination. Cleaning and drying before mounting help avoid a poor specimen–resin interface. The support example here is schematic; it does not predict resin shrinkage or specimen strength.
Work the surface
Cleaning removes the illustrated loose residue; it does not repair a scratch or replace a lost particle. Finer preparation addresses earlier surface damage. This model illustrates possible outcomes at a nominal plane; it does not calculate removal depth, real processing time or a material-specific recipe.
Inspect the evidence
Dark cavities can be original pores or sites of particle loss. Residue can hide details. The original structure is known only because this is a constructed specimen; a real investigation needs preparation records and additional evidence.
Choose the examination
A polished bulk cross-section can support suitable reflected-light or SEM work, but it is not an electron-transparent TEM specimen. An original surface-roughness question needs an intact surface. Instrument-specific checks still apply.
The sequence is compact: select a section; clean and support it; grind; clean and inspect; fine-grind; clean and inspect; polish; clean and inspect. Actual methods vary by material and question.
Model limits & sources
The original specimen is a synthetic 100 × 80 × 60 µm metal volume. XY, XZ and YZ sections are exact intersections with its fixed ellipsoidal pores and particles. Rotating the camera never changes the selected plane. Images are geometric inspection illustrations, not simulated detector intensities or acquired micrographs.
Preparation stages illustrate surface effects at the nominal section plane. Removed thickness, processing time, heat, chemistry and artifact probabilities are not predicted. A constructed particle-loss outcome remains lost on that virtual specimen. Real grinding can remove a damaged layer and expose a deeper plane; that progression is outside this fixed-plane model. A new specimen represents a virtual replicate, not physical reversal. Edge support and surface marks are qualitative examples; a numerical area describes only this field, not bulk porosity.
