The Best Software for 3D Printing Businesses
to Precisely Worth for FFF/FDM
By Mike Moceri, founder and CEO, MakerOS
Final month, I talked about how early on in my profession I undersold my 3D printing companies throughout one explicit job and misplaced out on a major quantity of income. It wasn’t lengthy after I spotted that I wasn’t the one one who was experiencing this problem in my business. I constructed an organization to handle the difficulty and along with my workforce, we developed a holistic methodology on learn how to precisely worth 3D printing initiatives that accounts for all facets of a 3D printing and digital fabrication enterprise.
At the moment, I’m taking it a step additional and can speak about how our confirmed methodology works for FFF/FDM 3D printing with PLA materials, however you possibly can apply these rules to another materials you fabricate with. Particularly, I’ll share with you the precise inputs you’ll want in an effort to successfully implement our methodology.
No matter how massive your operation is, there are particular bits of knowledge that you just want readily available to ensure that us to calculate your prices. Right here’s what you’ll want to know:
Let’s start by calculating your whole price per gram. To do this, you’ll want to know the next.
What’s your buy unit? For those who’re utilizing a desktop machine, you’re greater than doubtless shopping for it by the kilogram in your buy unit. However it could be offered by the gram, by the pound, or by the cubic inch, so be sure to double-check and have that data useful.
What’s the unit price in your materials? For those who’re buying your materials from Amazon or another respected reseller, you’ll usually pay between $15 to $45 for a 1-kilogram spool of PLA.
What’s your materials density in grams per cubic centimeter? Usually the density for PLA is 1.24 grams per cubic centimeter. Check with the fabric knowledge sheet offered by the producer.
With these values, you possibly can calculate a complete price per gram.
Subsequent, we have to perceive a couple of issues about your FFF/FDM machine.
What’s the precept price of your machine? For those who’re utilizing a midgrade, prosumer stage machine, you’re most likely within the $5K to $6K vary, however it could be as a lot as $10Ok.
What’s your machine’s lifetime hours? Particularly, you’ll need to know what the utilization time is in your machine. This may increasingly appear onerous to find out however in actuality, it’s not onerous to seek out out. Relying on who the producer is, there ought to be some life testing knowledge accessible to you. That could be within the guide or you might want to succeed in out to the producer. Alternatively, you possibly can estimate this quantity primarily based on expertise or if you count on to interchange it. In my private expertise, I’ve scrapped FFF machines approaching 6,000 hours over a 5 yr interval to both substitute with a brand new mannequin or as a result of the machine wasn’t price sustaining anymore.
What’s your upkeep and repair price in your machine, per yr? With a desktop prosumer machine, you’re prone to spend not less than 40 hours per yr simply sustaining the machine together with further consumables – how a lot do this frolicked and supplies price you? Alternatively, you might have bought a service package deal from the OEM or reseller, which for the instance machine talked about above, can vary between $500 to $1,000 per yr.
With all of those inputs, we are able to calculate the hourly depreciation and upkeep prices for the machine.
Fabricated Materials & Deposition Price
How lengthy does it take you to manufacture 1 cubic centimeter of fabric? Often known as the “materials deposition fee”, this is likely one of the most necessary elements for our calculations. How lengthy does it take to manufacture one cubic centimeter of PLA? There are a number of choices on how one can calculate this. You possibly can slice a 10x10x10mm dice at 100% density together with your typical settings and check with the output values. One other means, which is far more correct, is to take your cellphone or stopwatch and time the print from the very second it begins laying down materials to the second that the machine completes the print.
After all, relying on geometry, firmware, and different elements, the common materials deposition fee will range. Our objective right here is to get to a suitable baseline common. If you wish to be much more exact, then I counsel timing 10 print jobs with various geometries and weighing the ultimate prints. Time in minutes divided by the common weight of the prints in grams will calculate your common materials deposition fee and decide how rapidly you possibly can deposit 1 cubic centimeter of fabric.
With this data, and with what we already know, yow will discover how a lot materials you utilize in an hour and finally how a lot that prices you per hour.
Facility, Human Time, and Software program/Companies
Lastly, let’s incorporate the remaining ancillary knowledge factors to find out your prices.
What’s your lease and what are your month-to-month utilities in your area? That is your facility price.
How many individuals are required to function the machine and what’s their hourly fee? How lengthy does it take them otherwise you to arrange and tear down a machine after a print job? That is your human prices per print job.
How a lot do you pay in your CAD software program, your slicer, and your CAM or ERP system?
How about your accounting software program, your e mail and web suppliers, or another software program you’re utilizing each day? (fast plug: these are the prices that you just’ll consolidate and save on if you consumer MakerOS). When mixed and divided by the full working hours in a yr, you get your calculated prices that are a complete hourly price to your small business for each print job together with your FDM/FFF machine. So take a second and think about how lengthy your common job takes to print. Perhaps it’s 12 to 18 hours? As much as 48 hours for greater jobs? You may get a way of simply how massive that price is to you.
What’s the true price of printing with FFF/FDM?
Now let’s calculate the price to manufacture that total 1-kilogram spool of PLA. Decide a mean quantity for what number of print jobs you will get from all that materials, and multiply that by your human prices. When mixed together with your different calculated prices, you get a complete price to manufacture your whole materials, and I assure that you may be shocked at how giant this quantity is.
If our common deposition fee is 12.5g/hr, then we are able to assume that it’ll take roughly 80 hours to manufacture the complete spool. If on common your prints are 100g per print job, then on common you possibly can match roughly 10 print jobs inside a spool. Multiply your whole hourly prices by the quantity of hours that spool will final together with the human price on the common 10 print jobs per spool.
Don’t really feel discouraged in case your price to manufacture 1 spool is above $500. That’s completely regular and relying in your lease and machine, can exceed even $1,000.
What must you cost for FFF/FDM 3D Printing?
Okay, so what must you cost? What’s your margin? That reply varies relying on who your purchasers are and what your initiatives are for. For instance, in case your purchasers are within the shopper digital business, you most likely ought to cost upwards of an 80%-200% markup. However don’t be hesitant to go even additional. For a lot of of you, your time and work are extra priceless than you suppose.
Now you’ve gotten all of those inputs, yow will discover a minimal hour worth for every hour of printing time. Add your whole hourly price, your human time, and your markup, and collectively you get your worth.
