	Effective chip and dust extraction is vital for CNC milling aluminum because it prevents the "recutting" of debris, which causes poor surface finishes and can lead to tool failure. Aluminum is a gummy material that tends to fuse to the cutting bit when heat builds up; by extracting the chips immediately, heat can be carried away from the workpiece rather than trapping it. Beyond protecting the tool, a dedicated extraction system preserves the machine's mechanical integrity by keeping abrasive, conductive particles away from precision linear rails and sensitive electronics. Ultimately, maintaining a clear cutting path ensures dimensional accuracy and creates a significantly safer workspace by eliminating the respiratory risks of airborne metallic dust and the physical hazards of sharp, scattered shards since the machine is not enclosed.

==Creation Steps / Process==
I chose a similar approach to the extraction I did for the BlackBox CNC mill that is being renovated: A two part module that binds together using 10x40x3 mm neodymium magnets and encloses the machining area with brushes and connects to an adapter for the vacuum. This time it's the [[Festool CTM26 E AC (1)|Festool]] adapter.

Another difference is that the module is not mounted to a horizontal metal plate but needs to be directly attached to the spindle. For this the main part is clamped around the spindle using M5 screws. To test the design and since the longevity is not yet tested, most of it was printed in PLA but the main part was made using PETG since it exerts less creep than PLA which should help maintain the clamping force.

			=== Specific PA12 ===
			There are several variations of PA12 powder depending on manufacturer and additives. Important factors would be the mechanical properties, how easy it is to source and the price (/kg).

			From my research, it would be best to choose a material from the same company that the SLS printer is from (SinterIT) since they should have optimal print settings for this powder. Also their offers are quite affordable.

			# '''[https://sinterit.com/product/pa12-smooth-fresh-powder/ SinterIt PA12 Smooth]:''' cheaper kg-price and has a higher refresh rate
			# '''[https://sinterit.com/materials/pa12-industrial/ SinterIt PA12 Industrial]:''' a bit better mechanical properties

			The printer allows the use of 3rd party materials so these could also be considered, but they would definitely need testing to find the right print settings:

SLS Powder

LabCrow — Fri, 08 May 2026 09:49:02 GMT

creation of page

New page

SLS powder consists of thermoplastic micro-particles (45 to 90 microns in diameter). Unlike the resin used in SLA or the filament in FDM, SLS powder serves a dual purpose: it is both the building material and the '''support structure''' since the unsintered powder surrounds and supports the part during the print, allowing for incredible geometric freedom and nested batch printing.

=== General Properties and Characteristics ===
When working with SLS materials, you aren't just looking at a solid plastic part; you are looking at a porous, sintered structure. Key traits include:

* '''Isotropic Mechanical Properties:''' Unlike FDM prints, which are weaker along the Z-axis (layer lines), SLS parts exhibit nearly uniform strength in all directions.
* '''Surface Texture:''' Parts typically have a grainy, "sugar-cube" matte finish. This is due to the nature of fused powder particles.
* '''Porosity:''' SLS parts are naturally slightly porous. While they are structurally sound, they may require sealing if they need to be airtight or watertight.
* '''Thermal Stability:''' Most SLS powders have high heat deflection temperatures, making them suitable for high(er)-temp applications.

=== Refresh Rate ===
In SLS, you don't throw away the unsintered powder but mix it with "virgin" powder to compensate the aging/degradation of the powder beforr the next build.

=== Health and Safety ===
Working with SLS powder requires a bit more discipline than your standard desktop printer. Because the particles are so fine, they behave more like a fluid or a gas than a solid.

==== 1. Respiratory Risks ====
The primary concern is '''inhalation'''. Fine polymer dust can irritate the lungs and, with chronic exposure, lead to more serious respiratory issues. So the use of a protective mask during post-processing and powder recovery is advised.

==== 2. Combustibility ====
Like many organic dusts (including flour or sugar), high concentrations of polymer powder suspended in the air can be '''explosive''' if met with an ignition source. Special equipment (ATEX-certified) for the post processing and minimizing "dust clouds" is essential.

==== 3. Skin and Eye Irritation ====
The powder is a desiccant; it loves to suck moisture out of whatever it touches. Handling it with bare hands can lead to dry, cracked skin, and a stray puff of powder in the eyes is not a pleasant experience. Nitrile gloves and safety goggles are therefore also advised.

== PA12 as the best option for the space ==
If you want to change the material used, the necessary clean up to avoid cross contamination is a tedious task. Therefore it is reasonable to decide only to use a single material for most applications. For this '''Nylon 12 (PA12)''' is the best choice based on it's good fitting properties.

=== Exceptional Versatility ===
PA12 strikes a good balance between '''stiffness and impact resistance'''. It is rigid enough to hold its shape under load but ductile enough to be viable for snap-fits and some living hinges without snapping like brittle resins.

=== Environmental and Chemical Resistance ===
PA12 is remarkably stable:

* '''Low Moisture Absorption:''' Unlike PA6 (standard nylon), PA12 doesn't swell and loses very little mechanical integrity when it gets humid.
* '''Chemical Inertness:''' It is highly resistant to oils, greases, aliphatic hydrocarbons, and alkalies, making it ideal for various environments.

=== Refresh Rate ===
From a cost perspective, PA12 is also one of/the best choice because it has a very predictable refresh rate (usually around 20%–50% virgin powder), meaning you can run a highly efficient, low-waste production.

			As written in the page for PHA (but not for this project?), there is a need for a stabilizing frame (wood/aluminum). Wouldn't it be possible to produce a suitable aluminum frame with our CNC mill? This would also help with the cooling of the mold compared to wood and reduce the time needed between injections. [[User:LabCrow\|LabCrow]] ([[User talk:LabCrow\|talk]]) 10:05, 4 May 2026 (CEST)

explanation for material: Nylon (PA)

New page

{{MaterialInfoBox|material name=Nylon|synonyms=PA, Polyamide|contains=glass fiber (GF), carbon fiber (CF)|tools=[https://wiki.comakingspace.de/3D_Printers 3D printer]}}

Nylon is the common name for a family of synthetic polymers known as polyamides which were first developed by Wallace Carothers at DuPont in the 1930s as a "synthetic silk". Because of the following characteristics the polymer is still used in various fields and applications:

* '''High Strength and Durability:''' Nylon possesses an excellent strength-to-weight ratio and is incredibly resistant to abrasion.
* '''Elasticity:''' It can be stretched significantly and will return to its original shape, making it ideal for durable fibers.
* '''Thermal Resistance:''' It has a relatively high melting point and glass transition temperature for a plastic, allowing it to function in high-heat environments like engine compartments.
* '''Chemical Resistance:''' It stands up well against oils, greases, and many solvents, though it is notably hygroscopic, meaning it absorbs moisture from the air, which can alter its dimensions and flexibility over time.

----

=== 3D printing ===
In additive manufacturing, nylon (often referred to as '''PA''' for Polyamide) is considered a "prosumer" or industrial-grade material. While it is more difficult to print than standard materials such as PLA or PETG due to warping and moisture sensitivity, it offers functional capabilities that cheaper plastics cannot match. Based on it's different properties there are various variants enabling easier printing:

==== PA6 vs. Pa12 ====
The numbers refer to the number of carbon atoms in the polymer’s molecular chains.
'''PA6''' is generally considered the "standard" industrial nylon.
It has higher impact resistance and better mechanical strength at lower temperatures compared to PA12 and also has a higher melting point (220°C). However, PA6 is highly hygroscopic and absorbs water more aggressively and accommodates about twice as much as PA12.
PA6 is used when you need the '''highest possible strength and stiffness''' at a lower cost, and where the part will not be exposed to high-humidity environments that could cause it to swell or lose dimensional accuracy.

'''PA12''' contains less amide groups changing it's performance:
While the mechanical and thermal performance is slightly reduced, it is more dimensional stable and less hygroscopic compared to PA6 but also a bit more expensive.
PA12 is used for '''precise engineering''' because it doesn't warp as easily and is excellent for long-term outdoor use, chemical storage, or complex assemblies where parts must fit together perfectly regardless of the weather/moisture.

==== -GF / -CF ====
To further enhance the printability and dimensional accuracy glass (-g) or carbon (-c) fibers (f) are added in various amounts. The mechanical properties (besides stiffness) don't benefit from these additives as they reduce the strength of the bond between the lines.

Glass fiber (-gf) parts don't conduct heat and electricity, are heavier, less rigid but also less brittle and cheaper than carbon fiber (-cf) parts. CF-parts are slightly conductive which helps with dissipating static electricity (ESD safe) and almost as rigid as metal (depending on the carbon content percentage) while being very lightweight.
----

=== Annealing ===
Annealing is a post-processing heat treatment used to "relax" a 3D-printed or machined part. During the printing process, nylon is heated and cooled rapidly, which traps '''internal stresses''' and leaves the polymer chains in a disorganized, tangled state. Without annealing, the parts are more prone to warping over time and may fail prematurely under load due to these built-in stresses. Annealing accomplishes three main goals:

* '''Relieves Internal Stress:''' It allows the plastic to "settle," preventing future deformation.
* '''Increases Crystallinity:''' By holding the plastic at a high temperature, the polymer chains rearrange into a more organized, crystalline structure. This significantly increases the part's '''t'''ensile strength and stiffness'''.'''
* '''Improves Heat Resistance:''' An annealed part can often withstand higher operating temperatures than a non-annealed one.
* '''Reduced Effect of Hygroscopy:''' the reduction in performance due to water absorption can be slightly mitigated through the heat treatment.

==== The Process ====

# Place the part in a temperature-controlled oven.
# Gradually raise the temperature to just below the material’s '''Glass Transition Temperature''' or slightly above it, depending on the specific nylon grade (usually between '''70°C and 130°C''' for nylon).
# Hold the part at this temperature for a set duration (typically '''1 hour per millimeter''' of wall thickness) to ensure the core of the part reaches the same state as the surface.
# The oven is turned off and allowed to cool down '''very slowly''' with the part still inside. If the part cools too fast, new stresses will form, defeating the purpose of the process.

<blockquote>'''A Note on Shrinkage:''' Because annealing reorganizes the molecules into a tighter structure, the part will usually shrink slightly</blockquote>
