Digital Manufacturing FAQs

What does “L” mean in stainless steel?

The L indicates the low content of carbon in the stainless steel, L grades stainless steel can reduce the possibility of carbide precipitation in welding and other processes. Carbide precipitation may lead to intergranular corrosion, in which the material becomes more sensitive to possible corrosion. Generally, carbon is maintained at 0.03% or less; however, it may vary depending on the referenced code or standard.

Is stainless steel magnetic?

Some stainless steels are magnetic, while others are not. All stainless steel alloys are a type of steel, which contains the element iron. Due to the magnetism of iron, most steels are magnetic, the same for much stainless steel. So, stainless steel grades with iron in their composition are magnetic. All ferrite, martensite, and precipitation hardening grades are magnetic.

The high nickel and chromium content of T300 series austenitic stainless steel makes the alloy initially nonmagnetic. For example, the common austenitic steel 304 contains 18% chromium and 8% nickel. However, these alloys also become magnetic during the cold working process used to harden them.

How do you harden stainless steel?

Some types of stainless steel can be hardened by heat treatment, while other types of stainless steel need to be cold worked. Examples of cold working include swaging or drawing

16. What is the difference between FDM and resin 3D printing?

FDM (Fused Deposition Modeling) uses thermoplastic filament that is melted and extruded through a heated nozzle to build parts layer by layer. It is the most common and affordable type of 3D printing. FDM printers are great for:

  • Structural parts
  • Larger models
  • Printing in multiple colors (with dual extruders)
  • Lower-cost prototyping

Resin printing (like SLA, DLP, or MSLA) uses UV light to cure liquid resin layer by layer. Resin printers provide:

  • Higher resolution and detail
  • Smoother surface finishes
  • Better for miniatures, dental models, and intricate designs

However, resin printing involves:

  • Toxic materials
  • Post-processing (e.g., alcohol washing, UV curing)
  • More safety gear (gloves, masks)
17. What are the parts of an FDM 3D printer I should know?

An FDM 3D printer typically includes:

  • Print Bed: Where the model is printed.
  • Hot End: Heats filament to extrusion temperature.
  • Nozzle: Extrudes melted filament.
  • Extruder: Feeds filament into the hot end.
  • Gantry: Frame that moves the hot end or print bed.
  • Stepper Motors: Control X, Y, Z movement.
  • Screen: UI for controlling the printer.
  • Power Supply: Powers the entire unit.
  • Filament Spool Holder: Holds the filament.
  • SD Card/USB Port: For loading print files.
18. What is slicing and why is it important?

Slicing is the process of converting a 3D model (usually in STL format) into instructions (G-code) that your 3D printer can understand. Slicer software allows you to:

  • Adjust layer height, infill, support, and print speed
  • Set temperatures for bed and nozzle
  • Optimize print orientation for strength and quality
  • Preview each layer before printing

Popular slicers include:

  • Cura (free, open-source)
  • PrusaSlicer
  • Bamboo Studio
  • IdeaMaker
  • Simplify3D (paid)
19. What is the best 3D printing filament for beginners?

Start with PLA or PLA+:

  • Low warping
  • Easy to print
  • No enclosure needed
  • Prints at 180–220°C

Other beginner-friendly filaments:

  • PETG: Stronger and more flexible than PLA; prints at 230–260°C.
  • TPU: Flexible, rubber-like; requires slower speeds and direct drive extruder.

Avoid ABS as a beginner — it requires:

  • High temps (230–260°C)
  • Heated bed and enclosure
  • Ventilation (emits fumes)
20. What are infill, supports, and layer height in 3D slicing?
  • Infill: Determines how solid the inside of your print is.
    • Use 10–20% for decorative prints.
    • Use 50–100% for functional parts.
  • Supports: Temporary structures added to hold up overhangs.
    • Necessary for models with arms, bridges, or steep angles.
  • Layer Height: Defines print resolution.
    • Lower height (0.1 mm) = smoother finish, slower print.
    • Higher height (0.3 mm) = faster print, rougher layers.
21. Why is the first layer so important in 3D printing?

The first layer is critical for adhesion. If it doesn’t stick:

  • Prints may warp or fail entirely.
  • Check bed leveling.
  • Clean the bed with isopropyl alcohol.
  • Use a glue stick or adhesion sheet if needed.
  • Ensure proper Z-offset (distance between nozzle and bed).

Use a skirt or brim to prime the nozzle and ensure good flow.

22. What should I do if my 3D print fails? (Beginner Troubleshooting)

Here are common issues and solutions:

Issue Cause Fix
First layer not sticking Dirty bed, unlevel bed Clean bed, re-level
Layer shifting Loose belts, unstable printer Tighten belts, stabilize surface
Under-extrusion Clogged nozzle, low temperature Clean nozzle, check temp
Over-extrusion Incorrect flow settings Adjust flow rate in slicer
Nozzle clogs Old filament, debris Use cleaning filament or cold pull
23. What is automatic bed leveling and do I need it?

Automatic Bed Leveling (ABL) uses sensors to measure the bed’s distance from the nozzle at multiple points. It adjusts the Z-height dynamically during printing to ensure a consistent first layer.

Benefits:

  • Easier setup
  • More reliable first layers
  • Less manual calibration

ABL is recommended for beginners and anyone seeking less maintenance.

24. Can I print multiple colors or materials?

Yes, with:

  • Dual extruder printers – Two nozzles, two filaments
  • Multi-material units – Feed multiple filaments into one nozzle (e.g., Bambu AMS)
  • Manual filament swaps – Pause the print and change filament by hand

You can print different colors, support materials (like PVA), or combine flexible and rigid materials.

25. What is a 3MF file and how is it different from STL?

3MF (3D Manufacturing Format) is a modern file format that includes:

  • Model geometry
  • Color and texture data
  • Material info
  • Author and metadata

Unlike STL (which only stores shape), 3MF is like a PDF for 3D printing — it contains everything needed for printing without extra files. Many slicers now support 3MF.

26. What is bridging in 3D printing?

Bridging is when the printer spans filament over a gap without support. Example: printing a flat roof between two walls.

  • Works best with cooling fans enabled
  • Span should be short (under 25–50 mm)
  • May sag if speed or temp is too high
27. What is the best way to store 3D Printing filament?

Most filaments are hygroscopic — they absorb moisture from the air, which can cause bubbling, stringing, or brittleness.

Store filament in:

  • Airtight containers with desiccants
  • Dry boxes or filament dryers
  • Vacuum-sealed bags

Especially important for: PETG, Nylon, TPU, PC, and PVA

28. Can I print metal at home?

Not easily. True metal 3D printing (like DMLS) requires: Industrial-grade machines, Inert gas chambers, High-power lasers. However, metal-filled filaments exist — PLA blended with metal powders (e.g., bronze, copper). These can be polished to a metallic sheen but are still plastic-based.

29. What safety precautions should I take with 3D printing?

Resin safety:

  • Use gloves and a mask
  • Cure prints fully before handling
  • Ventilate the space

FDM safety:

  • Keep away from flammable materials
  • Supervise prints to prevent fire
  • Use printers in a well-ventilated area (especially with ABS)
30. What is the difference between SLA and DLP resin printing?

Both SLA (Stereolithography) and DLP (Digital Light Processing) use UV light to cure resin layer by layer, but they differ in how that light is projected. SLA uses a laser to trace each layer, offering high precision but slower speeds. DLP uses a projector to flash an entire layer at once, making it faster but with slightly less detail on very small parts. DLP printers are often more compact and affordable, while SLA systems are preferred for industrial-grade accuracy.

31. What is MSLA and how does it compare to SLA/DLP?

MSLA (Masked Stereolithography) is a sub-type of resin printing that uses an LCD screen to mask a UV light source, curing one entire layer at a time. It combines the speed of DLP with the affordability of consumer-grade hardware. MSLA is commonly used in hobbyist and prosumer resin printers and offers excellent detail with lower costs than traditional SLA. It’s ideal for miniatures, dental models, and other high-resolution applications.

32. How does binder jetting differ from DMLS?

Both binder jetting and DMLS are used to create metal parts, but the processes are fundamentally different. Binder jetting uses a print head to deposit a binding agent onto a metal powder bed. The printed part is then sintered in a furnace. It allows for faster printing and lower costs, but the final parts may have slightly lower density. DMLS, on the other hand, directly melts the powder using a laser, producing fully dense, high-strength parts. DMLS is ideal for critical applications, while binder jetting is better for cost-effective production.

33. What is Carbon DLS and what makes it unique?

Carbon DLS (Digital Light Synthesis) is a proprietary technology that uses continuous liquid interface production (CLIP) to cure resin with UV light and oxygen. Unlike traditional resin printing, DLS forms parts in a continuous motion, resulting in stronger, isotropic, and smoother parts with injection-molded quality. It’s ideal for end-use production, including medical devices, consumer products, and automotive components.

34. What is the difference between support materials and support structures?

Support structures are temporary elements printed with the same material as the part to prevent overhangs from collapsing. They are removed manually after the print is complete.

Support materials refer to a secondary material (often water- or solvent-soluble) used in dual-extrusion printers. These supports dissolve away after printing, resulting in cleaner surface finishes and allowing for complex internal geometries that would be impossible to remove manually.

35. What is the role of part orientation in 3D printing?

How you orient your part on the build plate can dramatically impact print quality, strength, and the need for supports. For example:

  • Minimize overhangs to reduce support material.
  • Align stress-bearing features with the layer direction for strength.
  • Position flat surfaces downward for better adhesion and aesthetics.

Proper orientation also affects print time and post-processing effort.

36. What is PLA+ and how is it different from standard PLA?

PLA+ is a modified form of PLA that includes additives to improve its strength, ductility, and temperature resistance. While standard PLA is easy to print and great for decorative items, it can be brittle. PLA+ offers a good balance between PLA’s ease of use and the mechanical strength of materials like PETG or ABS. It’s ideal for beginners who want tougher parts without sacrificing printability.

37. What is TPU and when should I use flexible filament?

TPU (Thermoplastic Polyurethane) is a flexible, rubber-like filament used to print parts that need to bend, stretch, or compress. Use TPU for:

  • Phone cases
  • Wearables
  • Gaskets
  • Shock absorbers

TPU requires a direct-drive extruder for best results, as it’s soft and can jam in Bowden tube setups. Print slowly and ensure good bed adhesion.

38. Can I request a sample or test part?

Yes. If you want to evaluate surface finish, color, material, or resolution, we can provide:

  • Sample parts
  • Benchmark models
  • Test coupons for functional evaluation

Contact us to request a sample kit.

Include any important specifications such as material type, surface finish, quantity, tolerances, and lead time. Once we receive your design, our engineers will analyze the part’s geometry and manufacturing requirements and provide a detailed quote, typically within 12–24 hours. The quote will include pricing, estimated lead time, and recommendations if any design optimizations are suggested.

5. What factors affect the cost of CNC machining?

Several key factors influence the cost of CNC machined parts:

  • Material cost: Some materials are more expensive or harder to machine than others. For example, aluminum is easier and cheaper to process than titanium or stainless steel.
  • Machining time: Complex geometries, tight tolerances, and deeper cuts increase cycle time and cost.
  • Labor and setup: Production setup, tool changes, and quality control contribute to the total cost.
  • Post-processing: Additional finishing like polishing, anodizing, or bead blasting adds cost.
  • Order volume: Larger quantities usually reduce the cost per unit due to economies of scale.
6. How can I reduce the cost of CNC machining?

To minimize costs, consider simplifying your part design by reducing complex features, avoiding deep cavities, and choosing materials that are easier to machine. Increasing wall thickness and lowering tolerance requirements where possible can also shorten machining time. Additionally, consolidating parts into fewer components or increasing order volume helps reduce per-part costs significantly.

7. Does delivery time affect pricing?

Yes, delivery time is a major cost driver. Rush orders usually incur expedited fees due to machine prioritization, extended working hours, and express logistics. If your project allows for a standard or flexible lead time, you can benefit from lower pricing. Always communicate your timeline clearly when requesting a quote so we can provide scheduling options that fit your budget.

8. What materials are available for CNC machining at CNCLATHING.COM?

10. What is the difference between CNC milling and CNC turning?

CNC milling involves rotating cutting tools that move around the stationary workpiece to remove material and create features like slots, holes, pockets, and contours. CNC turning, by contrast, rotates the workpiece while a stationary tool removes material. It is best suited for cylindrical parts such as shafts, sleeves, and bushings. CNCLATHING.COM offers both services, and hybrid machining if your part requires both milling and turning operations.

11. What tolerances can you achieve?

We can achieve tight tolerances of up to ±0.004 mm (±0.0002 inches) depending on the material, machining process, and part complexity. For most general-purpose parts, ±0.05 mm is standard. If your project requires high-precision components, please specify this in your quote request so we can recommend the appropriate process.

12. How does the design process work?

The CNC machining process starts with a 3D CAD file, which is converted into machine-readable code (G-code) using CAM software. This code guides the CNC machine to cut, drill, and shape the raw material into the final part. We recommend designing parts with CNC-friendly features such as uniform wall thickness, accessible geometries, and minimal undercuts to reduce cost and improve manufacturability. Our engineers are available to assist with DFM feedback during the quoting stage.

13. Can CNCLATHING.COM help with prototyping?
