Form 3 was my 1st printer, the operating cost is insane. $100 for a replacement tray that doesn’t last long, $150 for 1 leader of resin, chipped so you can’t use 3rd party resin. Saturn 4 is under $500, prints at 12k Ai intergraded, cheap to operate and maintain. 5k for a resin printer is insane.

I think a key point that was missed in this video was the cost and leadtime of even a simple plastic injection mold. This technology allows you to have 1000 parts today/tommorow instead of weeks/months. Then take into account that if you have a mold and need to make a change to the part, your back to high cost and downtime to get that change made. If the resin material is sufficient for your needs, I can see the justification behind resin printing plastic parts for end use.

In my opinion the resin parts will be unusable for real world use, they probably won't survive being stored in a shipping truck in summer due to low heat deflection temperature. Maybe if you're going to print them and use them in an office which is always climate controlled (and out of the sun).

Cost per part is going to be wildly different since your resin costs significantly more than, if we also include the cost for the build platform, tanks, etc. price per part will be 4-10x more. Also tooling lead time is true for a full production tool but not a rapid tool made in China which is typically 3 weeks, and can last for 10,000parts typically.

Their new cost per Liter is $99 for general purpose black. If considering each part uses on average 20ml of material it's safe to assume you can get 50 parts per cartridge. 99 dollars divided by 1000ml =$0.09/ml or $1.98/part

What about cleanup? The time/labour required for cleanup of resin parts should be accounted for in such a comparison. So to for injection molding cleanup. I'm an avid 3D printer, so this isn't a knock on printing or your products, more an appeal for clarification, or asserting a requirement of fairness.

@orbitoclast-sq3dw 3 ай бұрын

both injection molding and 3D printing require post processing and cleanup. both post process methods were not included here because the intention of the comparsion is the forging of the part itself. Post processing times vary for both machines depending on type, materials used, etc.

The real win for Formlabs SLA printing is that you can do plastic injection mould production volumes while being able to produce part designs that can't be injection moulded. It is the only way to justify the added cost. Large production volumes of small high value, low material volume, high detail parts is the best niche for this style of manufacturing. It opens design possibilities that were previously unattainable.

Quick clip shows the parts printed directly on the build surface, no supports needed for this design. This is a very specific example, but realistic for a subset of designs. If part designers switch our mindset to designing for additive manufacturing, the subset will grow, possibly including parts that are impossible to mold.

This material is Black Resin V5. Here's the technical data sheet. formlabs-media.formlabs.com/datasheets/2401897-TDS-ENUS-0.pdf. Compared to ABS, it has similar stiffness (2.7 GPa flexural and tensile modulus), higher strength (62 MPa UTS), and much lower toughness (32 J/m notched izod, 13% EAB). We also have other materials (Durable, Tough 1500, Tough 2000) that are closer to the toughness of ABS.

@airborne0x0 3 ай бұрын

@@Formlabs From your datasheet the heat deflection temperature is 54C@1.8MPa/ 61C@0.45MPa, or 57C and 69C post cured. Tough 2000 post cured is similar 53C/63C. For ABS it is approx 88C and up. This makes all the difference for a real world application where someone might have to use it outside on a hot day or store it in a vehicle in the sun (or simply ship it where it might be in those conditions). Also in my experience your Tough 2000 resin has a long term amorphous solid property that tends to distort/warp the part over time at room temperature. As a result both of these are unusable for any of my real world engineering cases. I would really encourage you to develop some better engineering resins.

I see each print makes a bunch of clips but each injection molding only makes 1. Why couldn’t the injection molding machine make 10-20x more by injection molding multiple at once? I assume quality/reliability?

@sambooo07 3 ай бұрын

You would need a much more complex and expensive mould, plus more points where the plastic is injected. The lead time and cost of this would make it so difficult that you could make this to make sense only if you create hundreds of thousands of not millions of parts. If that is the target volume, then yes, that's more efficient... But for shorter batches, it's way better to adopt printing... And depending on the part, you could rotate it, place more per batch and even stack them too, making it even more efficient for the printing case (this is not always an option).

@bloodtastesirony 3 ай бұрын

No; each time the mold fills it's making 2 parts (see 0:34) -- it's 2 parts connected by the sprue and runners which need to be clipped off at the gates to release the 2 parts (plus the scrap plastic that can be reprocessed). This is called a 2-cavity mold.

@darrennew8211 3 ай бұрын

Also assumes the parts line up nicely on the plate. Make something you can't pack them together, and you're not going to go nearly as fast. Add a 10mm rib coming out from both sides of the part, and now the 3d print take 4x as long because you can't fit a bunch in parallel.

Most 3D printing resins will deform over time. They are not made to last long and stay robust. I would argue that even for low production, these printed parts are not suitable for long-term use. (We have several Form 3s in our shop, and they are definitely one of the best tools for prototyping.)

Looks great. I don’t think it’s the right application and comparison to injection. Take LEGO as an example, you can’t have that precision, surface treatment, color variations or volume amortization where you crank out millions of bricks. I mean, you are trying to beat something that gets injected in a second with printing layers? Only way you are achieving that is adding more 3d printers, but your mold can have more parts too. I have 3d printer, but I have it for different applications. It’s getting there but it ain’t there yet. And IPA man, just that alone is pain in my a** 😂

Cool video but you've just cherry picked your cycle time to suit the study. From the video that 2 cavity mould is running a cycle time of 50 seconds. Ive a medical manufacturing backgroup and we have extremely conservative holding times and our cycle times are about half that. I've worked in high volume manufuring where 64 cavity moulds have cycle times of 3.5 seconds. 3D printing is great and has its place but injection moulding is almost always a better process for high volume manufacturing of plastic products.

Hiya! Its to compare prototyping capabilities! I work in injection molding, and getting a unit tool made for prototyping can run you quite a bit of money (in their example I think they said $50k which sounds accurate.) I think they are more speaking to the speed of prototyping here. It can take me 10 weeks to get a tool made and into a press, only to find out we need to adjust certain aspects of the part and send it back to be recut.
