3D Printing Best Practices

Outpost 3D provides ready-to-print files for practical outdoor, EDC, and homesteading gear. Here's how to go from download to finished print:

1. Browse the library or check the latest weekly drop for new releases.
2. Download the file format that matches your workflow — STL for custom slicing, or G-code for plug-and-print.
3. If using an STL, open it in your slicer (Bambu Studio, PrusaSlicer, Creality Print, etc.) and apply the recommended settings included with the download.
4. If using G-code, transfer the file directly to your printer via USB, SD card, or network upload.
5. Print, inspect, and field-test before relying on the part.

You'll encounter several file formats when downloading from Outpost 3D. Here's what each one is and when to use it:

• STL — The universal 3D model format. Works with any slicer and any FDM printer. Use this if you want full control over your print settings.
• G-code — Machine-ready instructions for a specific printer. No slicing needed — just transfer to your printer and start. Settings are already optimized.
• 3MF — A modern project file that bundles the model with orientation, support placement, and slicer settings. Supported by Bambu Studio and PrusaSlicer.
• .bgcode — Compressed binary G-code used by newer Prusa machines. Same as G-code but smaller file size and faster transfer.

Material choice directly affects strength, flexibility, and weather resistance. Here are the three materials you'll see most often at Outpost 3D:

If you're using our pre-sliced G-code files, settings are already baked in. For STL files, here are general starting points:

A solid first layer is the foundation of every successful print. If the first layer fails, the whole print fails. Here's how to get it right:

• Clean your bed before every print with 90% isopropyl alcohol (IPA). Fingerprints and dust cause adhesion failure.
• Run auto-leveling or Z-offset calibration regularly. Even a small offset can ruin adhesion.
• Check bed temperature: PLA+ needs 60–70°C, PETG needs 80–95°C. Too low and nothing sticks.
• Use a brim or raft for parts with small footprints. This adds extra surface area for the first layer to grip.
• Slow your first layer to 15–20mm/s for the best adhesion. Most slicers have a separate first-layer speed setting.

Many Outpost 3D files are designed to print support-free, but some more complex gear requires them. Here's the general rule:

• Overhangs beyond 45° usually need support material underneath.
• Bridges (horizontal spans between two points) up to about 40mm can often print without supports if cooling is adequate.
• Check the file description — we always specify whether supports are needed and where.
• Pre-sliced G-codes already include support placement, so you don't need to configure anything.

When adding your own supports in a slicer, use tree supports for organic shapes and normal supports for flat overhangs. Set support density to 10–15% for easy removal.

Here are the most frequent problems and the fastest path to fixing them:

Every file on Outpost 3D is tested before release, but 3D printing involves variables we can't control — your printer, filament batch, ambient temperature, and settings all affect the final part. Before relying on any printed gear in the field:

• Stress test at home first. Apply force, hang weight, flex it, drop it. Find the failure point before you're in the woods.
• Check layer adhesion. Try to peel layers apart at edges. If layers separate easily, increase nozzle temperature or slow down your print speed.
• Test fit with hardware. If the part interfaces with screws, bolts, or other components, verify the fit before heading out.
• Inspect for gaps or voids. Hold thin-walled parts up to light. Gaps indicate under-extrusion that will weaken the part.

Proper storage extends the life of both your filament and finished prints.

Filament Storage

• Store filament in sealed bags or dry boxes with desiccant packets.
• Wet filament causes stringing, bubbling, and weak layer adhesion. If you hear popping during printing, your filament has absorbed moisture.
• Use a filament dryer before printing with spools that have been sitting out. 4–6 hours at 45–55°C works for most materials.

Finished Prints

• PLA+: Keep away from prolonged heat. Store indoors when not in use.
• PETG: Handles sun and moisture well. Fine for long-term outdoor storage.
• TPU: Flexible and durable. Store flat to avoid permanent deformation.
• Clean printed gear with mild soap and water. Avoid solvents unless the material is rated for it.
