3D Printing Guides · ABS

This guide explains how to prepare an existing simulator model for printing with ABS filament: a solid strand of acrylonitrile butadiene styrene plastic. It also explains what to send to a printing service and how to inspect the returned component.

You need the model files and the simulator's build instructions. Use this guide when those instructions specify ABS. If the material or printing process is unknown, return to Confirm required process.

This is a general preparation workflow. The simulator developer must supply the required dimensions, structure and acceptance checks. A successful ABS print does not establish its suitability for a training task.

The drawings use generic shapes. They explain relationships; they are not software screenshots, anatomical models or evidence of successful prints.

You need a compatible slicer, an ABS-capable printer, the specified filament and the equipment instructions. Follow Steps 1–9.

Prepare the printing location first. ABS printing releases particles and gases. A heat-retaining enclosure does not by itself establish adequate emission control. Use the workshop's specified extraction or evaluated filtration system. Ventilation must control emissions while preserving the printer's required operating conditions. Particle filtration alone does not address gases.^[4]

If suitable equipment or emission controls are unavailable, use a provider that can meet the requirements.

1. Complete Steps 1 and 2.
2. Send the original model files, revision details, quantities, source licence and build instructions.
3. Ask the provider to confirm ABS compatibility, required dimensions, orientation, internal structure and finishing requirements.
4. Resolve missing requirements and proposed substitutions with the simulator developer before production. The provider prepares the machine-specific file.
5. Request a record of the filament, settings and deviations. Inspect the returned components using Step 9.

Expected result: the provider can identify the files and requirements. Its ability to print the shape alone does not establish training suitability.

Obtain the files from the simulator developer's source page. Confirm the model name, required components, revision and permitted use. Save the original filenames and instructions together.

STL describes coordinates without a length unit. Check the intended units and dimensions with the source; a displayed scale of 100% cannot establish the correct size.

Expected result: each required STL is saved with its source and revision. You or the provider will check it in the slicer at Step 5. If a download fails, return to its source page. Check that you saved the STL, not a webpage. Do not substitute another revision without checking its requirements.

The Visible Ear Simulator download page recommends transparent ABS. Two available files are DeltaHRP (STL) and VES (STL). These represent alternative anatomical datasets, not a matched pair. Choose the dataset required for your training activity.^[5]

The prepared files use CC BY-NC 4.0, with additional permissions on the source page. These include service printing for an institution's own non-commercial use. Retain the specified attribution and check the full terms. Follow the source links; this guide does not redistribute or relicense the files.

Before printing: obtain ABS-specific model settings from the developer. The linked 2023 paper describes Lay-brick, a different filament; its temperatures and infill settings are not an ABS recipe.^[6] These downloads do not establish an ABS-validated build in TissueDB.

Keep the source instructions beside the slicer. Record:

• Material and equipment: ABS product, filament diameter, required colour and compatible printing process.
• Size and orientation: units, dimensions, permitted scale and the intended face on the build plate.
• Structure: layer height, walls, top and bottom layers, infill, supports and adhesion features.
• Finished-part checks: dimensions, assembly fit, finishing and any task-specific acceptance criteria.

A default is a software starting value. It is not necessarily a simulator requirement. Mark missing or conflicting information explicitly.

Expected result: you can separate stated requirements from defaults. If an item is unclear, ask the developer about that item and identify the file revision. Printing-service users can then complete the handoff.

Use the slicer recommended for the printer. Obtain it from its official provider. Control names vary between applications and versions.

1. Add or select the exact printer model.
2. Match the configured nozzle or print core to the installed hardware. The nozzle is the tip that deposits plastic.
3. Confirm the filament diameter and the printer's usable build volume: its available width, depth and height.
4. Check that the hot end, heated bed and enclosure can meet the selected ABS product's requirements within their operating limits.

A profile is a saved group of settings. Select the appropriate equipment profile before applying the simulator's requirements.

Expected result: the software configuration matches the machine. If the printer or installed hardware is unknown, consult its operator. Do not select a different machine merely to clear a warning.

ABS needs controlled printing conditions. It can warp as it cools, so follow the manufacturer's enclosure and build-surface instructions.^[7]

1. Check the spool label against the specified ABS product, diameter and colour.
2. Select its compatible material profile. If none exists, obtain the supplier's setup instructions; do not use an unrelated profile.
3. Check nozzle, bed, chamber and cooling settings against the printer and filament instructions. Use chamber heating only if the equipment supports it.
4. Follow the filament maker's storage and drying instructions when required. Prepare the specified build surface and adhesive.

Manufacturers publish product-specific temperature, fan and drying guidance. For example, Bambu's ABS data sheet specifies its own printing conditions; these are not universal settings for ABS.^[8]

Expected result: the actual filament, selected profile and equipment agree. Resolve conflicts before proceeding; changing only the nozzle temperature does not convert another material's setup into an ABS setup.

Use the slicer's Open or Import command. Select the intended STL and confirm its identity. The patterned strip in the following drawings identifies a generic base.

ABS can shrink after cooling. Do not apply an automatic scale increase. Where fit is critical, agree a representative test print with the developer and printer operator. Measure the cooled test before committing to a full build. Fit also depends on geometry, orientation and calibration; there is no universal clearance.^[10] Agree any correction with the developer, especially where anatomical dimensions or mating parts matter.

Expected result: the identified model has the required orientation and dimensions and fits the usable volume. Resolve an unexplained size or fit before continuing.

Use the simulator's requirements within the compatible ABS profile. The drawings explain four features without prescribing their settings.

Adhesion features serve a different purpose. A brim attaches around the base; a raft sits beneath the part; a skirt is separate. Use the specified option and inspect the space it needs.

Expected result: settings match the source and equipment. If a setting is missing or conflicts with manufacturer guidance, resolve it before slicing. Do not substitute a similarly named pattern without confirming equivalence.

Select Slice, then open the layer preview. In Cura, Preview shows the generated paths and provides layer and feature-visibility controls. Inspect your actual output, using the drawings as reminders.

Expected result: each component has the required planned structure and no unresolved warnings. If the preview is wrong, correct Step 5 or 6 and slice again. Share persistent errors with the developer or operator, including the filename, configuration and preview.

1. Use the export format and transfer method specified for your printer.
2. Name the output so its model, revision and target machine remain identifiable.
3. Retain the original STL and record the slicer version, profiles, orientation, scale and settings.
4. Save an editable slicer project separately if required. For Cura, a complete project can preserve the model and configuration; it is distinct from the generated print output.^[12]

Expected result: you can identify the printer-ready output and its target. If the printer rejects it, check the configuration and export method. Renaming an STL extension does not create G-code. Re-slice after relevant equipment or setting changes.

Prepare and operate the printer according to its instructions. Use the specified emission controls, enclosure and build surface. Keep drafts away from the print. Follow the equipment instructions for hot surfaces and moving parts.

Let the component cool as instructed before removal. Avoid forced cooling or opening the enclosure contrary to the printer guidance. Remove supports carefully; fragments can have sharp edges. Use appropriate eye protection. Printing-service users start with these checks:

1. Confirm every required component and its recorded material and revision.
2. Inspect for lifted corners, distortion, cracks, separated layers and incomplete features.
3. Remove required temporary structures. Check that fitting surfaces and channels are accessible and undamaged.
4. Measure specified dimensions after cooling. Check assembly fit and the developer's acceptance criteria.
5. Record deviations. Keep damaged or nonconforming components out of the build until the problem is resolved.

Do not add acetone smoothing as an improvised finishing step. It can alter dimensions and edges or distort thin features, and it introduces solvent hazards.^[13]

Follow the simulator's specified cleaning procedure. Removing visible debris does not establish disinfection or sterilisation; these are different processes.^[14] This guide supplies no validated cleaning or sterilisation process for a simulator.

Expected result: the component meets the supplied build checks before assembly or training. If acceptance criteria are missing, ask the developer. Appearance alone cannot confirm tactile behaviour, mechanical performance or training effectiveness.

• Unexpected size: check units, source dimensions and scale before resizing.
• Model outside the print region: check equipment, orientation and space for supports and adhesion features.
• Lifted corners or split layers: review the ABS profile, build surface, enclosure and cooling with the printer operator.
• Poor fit after cooling: compare measurements with the source and test feature. Resolve the cause before scaling the complete model.
• Missing preview features: check visibility filters and intended cavities, then investigate unexplained gaps.
• Missing or conflicting requirements: identify the exact file, setting and equipment when asking for clarification.
