Welcome aback to allotment II in this ensemble of techniques with laser-cut Delrin. Thanks for abounding of the abundant insights forth the way in the comments. In this guide, I’d like to go over some of the added actual kinks that arise to apperception back accepting started with this material.
When it comes to shopping, there are a array of suppliers to accept from, but there are a few key words and thoughts to accumulate in mind.
First, Delrin, is the “brand name” that refers to the Acetal homopolymer. Variants may additionally be labeled, acetal or acetal homopolymer. Delrin’s accustomed blush is a bendable white, but dyes can booty it into a ambit of added colors. Black and white are, by far, the best common, though.
In the antecedent guide, all of the examples were cut from a small range of area thicknesses (0.0625[in], 0.09375[in], and .125[in]) sourced from OnlineMetals. As the array of the area increases, the tolerances on the array appraisement will additionally become added loose. You ability buy a .125[in] bowl and acquisition it to be .124[in] in some places and .126[in] in others. If you acquirement a .250[in] sheet, however, you’ll acquisition that it may alter as abundant as .126[in] billowing though!
Despite McMaster-Carr actuality my go-to band-aid for one-off prototypes area accelerated body iterations trump BOM cost, I don’t acclaim purchasing Delrin from them as their bedding don’t accept a apathy appraisement and generally gets alien angled in (oddly sized) boxes. (Seriously, has anyone abroad gotten a few oddly-sized parts in a gigantic McMaster-box before?)
Extruded Delrin has centralized stresses congenital up central of the sheet. There are a array of affidavit why this could be the case, but my bigger anticipation is that the banishment action at the branch after-effects in altered genitalia of the bedding solidifying at altered times as the area cools, possibly causing some genitalia of the area to bind from the cooling afore added gooier sections accept yet to accomplishment cooling. What this agency for you is that as your allotment gets lased out of the sheet, you’re, in a sense, abating that stress. As a result, the allotment that you cut–especially for attenuate sheets–may arise out of the laser cutter hardly warped.
Assuming that the area put into the laser cutter was collapsed in the aboriginal place, again you can agreement that appearance like holes and pockets will be the actual about ambit to anniversary added back the allotment is advance out flat. To abrade out genitalia in their final application, I’ve arise up with two solutions.
Because the about area of the holes is precise, you can bolt plates calm with collision to abrade them out.
This is the adjustment that I acclimated in the GameCube-bot-2’s chassis. With assorted standoffs admitting the amplitude and breadth of anniversary allotment the anatomy as a accomplished pulls all bedding flat.
Alternatively, you can additionally bury holes for bounce pins and sandwich two plates calm such that the pins authority both plates collapsed about to anniversary added and abolish their warping. Bounce pins anchored in Delrin can additionally serve a bifold purpose in that you can “double-up” your Delrin plates for thicker geometry. Below, I doubled-up on some eighth-inch plates to bigger board a flanged bearing.
Alas, for CO2 lasers in the 40-to-60-watt class, we’re pretty-much ashore with this affection actualization on the edges of all our parts. By “taper,” I’m apropos to the askew edges that arise on Delrin (and some other) laser-cut parts. This askew angle is a appropriate of the way the laser cut lases through material.
If we brainstorm the axle absorption into a baby dot in the aforementioned way we focus the sun’s ablaze through a accumulative bottle to bake paper, it’s not too difficult to brainstorm the “coned” appearance that the collimated ablaze takes on as it exits the lens. above the point of focus, this cone admirers out into addition cone. This “double-cone” moves through our allotment acid material. Depending on area we focus the lens above-mentioned to acid will actuate the appearance of the lens–unless we cut our allotment in assorted passes with altered focal credibility per pass. In the spirit of repeatability, I’ll opt for an addition workaround.
Getting about this affair absolutely is about impossible, so it’s usually easier to architecture about it. Press-fit genitalia that blow absolutely central the lased pocket, such as bearings, are usually experiencing a tighter clasp on one end, rather than the other. Hence, they’re acceptable to pop out. To get about this issue, you can either opt for their flanged counterparts or sandwich two Delrin plates calm with opposing askew edges to bigger authority the allotment inside.
Delrin is well-know for actuality chemically-inert–so abundant so that it’s about absurd to acquisition a cement that bonds Delrin to addition surface! While there’s absolutely an befalling to try melting it calm in this case, I’ll say, for now, that gluing Delrin is out-of-the-window of possibilities for reliable techniques–especially in models that charge to action in some way besides looking nice.
Sometimes, holes charge to be just the appropriate admeasurement to board the bound tolerances of metal-to-Delrin press-fits. Back that’s the case, we can capitalize on the laser cutter’s “stronger parts” and blow up the blow manually. In this case, the laser cutter excels at accomplishing bound tolerances amid about dimensions, such as the agreement amid holes. On the flip-side, the laser cutter doesn’t excel at nailing the exact ambit of those holes with bound tolerances. Consequently, we can undersize our holes, lase them out, and ultimately accompany the holes to their final ambit with the appropriately sized assignment bit or reamer. It’s a baby bit of added work, but it’s a agreement that assertive holes can accommodated tighter altruism constraints.
Delrin tends to bastardize beneath its own weight. If stored on end, it will advance a angle over time that makes it actual difficult to cut analogously in a laser cutter back the axle is focused at a anchored ambit from the lens. To accumulate problems with force out of your Delrin side-projects, I’d acclaim autumn bedding flat.
Thanks for affability in for this two-part Delrin special. Don’t balloon that while these techniques ability lay out a foundation, there’s absolutely abounding more undocumented tricks account aggravating with this material–and that’s area you arise in! If you accomplish any discoveries on your own, be abiding to accumulate us acquaint in the comments. As a community, we can accumulate adorning our knowledge-base as we keep rolling out the projects.
